Class Topics Welcome and Introduction What is ArcGIS? What is ArcMap?
Getting around ArcMap Working with Layers Accessing DNR Data Exploring Data Working with Tables Labels, Annotation, and Graphics Building Layouts and Printable Maps Discuss Agenda

What is ArcGIS? ArcGIS is a ‘family’ of software products produced by ESRI. Instead of having all individual products such as Arc/INFO, Arcview, MapObjects, they combined them into one software called ArcGIS.

What is ArcGIS? Licensed at different levels of capabilities ArcView
Cheapest, entry level software. Edit shapefiles and Personal GeoDatabases. ArcEditor Mid-range pricing, increased functionality. Supports multi-user Database editing ArcInfo Expensive, full geoprocessing capabilities, designing and build multi-user databases, establish topologic relationships between datasets ArcView – things like Rectifying Air Photos, Map Topology Editing, Model Building are all part of ArcView license levels. When you purchase ArcGIS, you get all the CD thou you may not be able to use all the functions. e.g. Division, Forestry – managing data which is edited by the multiple users, so they need to get ArcEditor license of the ArcGIS. The key is : What to edit, how it was edited.

What is ArcGIS - Extensions
ArcGIS has “Extensions” that extend the core functionality of the program Spatial Analyst – grid processing 3D Analyst – 3d modeling More… These are the same no matter what level of software licensing you use Can build extensions for ArcGIS with custom functionality for specialized purposes

What is ArcGIS? Program Modules
ArcMap – module for interactive data editing, making maps and analysis. ArcCatalog – module for browsing, accessing, and managing (creating and organizing) data ArcToolBox – an environment for performing geoprocessing operations on spatial data When you build database, you use ArcCatalog. ArcToolBox is an equivalent to the DNR Arcview Toolbox.

What is ArcGIS? – ArcMap Interactive Map-Based Tasks Mapping Editing
Queries Analysis Printing Open ArcMap and show folks the Basic look and feel – real quick tho’…

What is ArcGIS? - ArcCatalog
Browse your data Preview the data and the table Create, define and manage data and projects Create and view metadata Hint: this is where you can create a shapefile or geodatabase from scratch Open ArcCatalog and show folks the Contents, Preview and Metadata Windows.

What is ArcGIS - ArcToolBox
Geoprocessing commands organized and accessed in ArcToolBox Build custom tools and analysis models using ModelBuilder Share models and tools Open the ArcToolBox TOC – this is the ArcGIS 9.0 way of doing things. If users had used ArcMap 8.0 they would have seen something different. Dockable and floating….. It is organized by the Function – Tool Box, Open Tool box, then you see all tools. Show the example of the ModelBuilder? - make an example.

What is ArcGIS? ArcGIS is just one part of a larger line of software available from ESRI, including: Desktop GIS ArcGIS Engine, ArcInfo, ArcEditor, Arcview, ArcReader, ArcGIS Desktop Extensions Server GIS ArcGIS Server, ArcGIS Image Server Mobile GIS ArcGIS Mobile, ArcPad ESRI is the “Microsoft” of GIS… Just a note to let them know that they will hear about other ESRI software products and that ArcMap is part of a larger GIS solution. ArcIMS, ArcServer, and ArcEngine are more enterprise software – usually users don’t need them.

What is ArcGIS? Enterprise ArcGIS License agreement between ESRI and Minnesota State Agencies Two types of licenses: Stand-Alone licenses – for field use and sites with limited/no network connectivity Shared license Licenses checked out from central license server Users must be on a network Make sure that they understand that they can all load and experiment with ArcGIS if they are not a registered user. They need to get a hold of those folks and go through the process. Shared license is most economically. At this point, we assume that 3 users can share one shared license – this requires us to give up one Arcview 3.3 license. Each unit decide who they want in the designated users’ list – not GIS section. Those who wants to join the designated users, talk to your GIS rep.

What is ArcGIS? Stand-Alone Licensing
Users have the ability to Borrow a shared license for stand alone (disconnected) use for up to 30 days at a time. This is simply a graphic that portrays the previous slide Make sure you point out that Extensions are available with all licensing levels. Corporate Geodatabases support multi-user editing and are centralized and use large databases such as Oracle In ArcView you can create temporary topology called “Map topology”. With Arc/Info you can create permanent topological rules and relationships Most users in the DNR will be using ArcView license and that will do everything that Arcview 3.3 would do. Even with Arcview license level, you can still use ArcMap, ArcCatalog, ArctoolBox, Spatial Analysis extension, Network Analyst extension, 3D Analyst, and Geospatial Analyst

What is ArcGIS? Enterprise License Agreement (ELA) includes:
ArcMap Desktop software Stand alone Arc/Info licensing Unlimited shared Arc/Info level licensing Extensions Unlimited Spatial, 3D, Geostatistical, Network, ArcPublisher, Mapplex ArcGIS Server Products This is simply a graphic that portrays the previous slide Make sure you point out that Extensions are available with all licensing levels. Corporate Geodatabases support multi-user editing and are centralized and use large databases such as Oracle In ArcView you can create temporary topology called “Map topology”. With Arc/Info you can create permanent topological rules and relationships Most users in the DNR will be using ArcView license and that will do everything that Arcview 3.3 would do. Even with Arcview license level, you can still use ArcMap, ArcCatalog, ArctoolBox, Spatial Analysis extension, Network Analyst extension, 3D Analyst, and Geospatial Analyst

Introduction to ArcMap
Lesson Overview This lesson covers the core concepts of the ArcMap User Interface (UI) and how to use them to display data ArcMap User Interface components Toolbars and Context Menus Data Frames Layers in ArcMap Just an outline of what we will do for the next lecture….. Terminology differences – there are a few things different between ArcView and ArcMap… We will talk about ArcMap interface components that are common to all programs Data frames – the equivalent of an ArcView 3 View document Layers – the equivalent of an arcview 3 theme

The ArcMap interface is composed of: Table of Contents – displays legends, selection, and source information for layers Display Area – This is where the map is displayed Data View – displays data (View) Map View – displays map layout (Layout) Status Bar – At the bottom of the display showing status, coordinate information, etc. Toolbars – Organized sets of commands and tools Show the ArcMap and show each interface described in this page. TOC – three tabs: Display, Source, and Selection tabs. The concept of “active theme” is gone. Instead of making a theme active, you need to make sure that a layer or layers that you want to select is selected. Note: You can make select multiple layers as selected layers. Show the list of Toolbars available.

Toolbars (can be moved and docked) Table of contents Display Area Status Bar

Commands and buttons for ArcGIS are organized into “Toolbars” Toolbars can be docked or floating and can be turned on and off Lots of toolbars exist – Use the CUSTOMIZE | Toolbars menu option to see toolbars and their display status If you lose a toolbar, look to see if it is checked on in the list

Docked Toolbar Floating Toolbar

Don’t open too many toolbars at any given time Toolbars can clutter the screen and make things hard to find Can be docked all over Commonly used Toolbars: Standard – standard tools New, Open, Save, Print, etc. Tools - tools for interactive display navigation Draw – tools for working with graphics and text Editor - tools for editing data Layout – tools for working on layouts Use Control key while you are trying to move the Tool Bar, but do not want to dock it. - Show this to audiences.

Standard Toolbar Layout Toolbar Tools Toolbar Show – drag out the Tools and show them the name of the tool bars! Draw Toolbar

Toolbar Madness: A condition brought on by the inability to find toolbars The ability of Toolbars to be moved around provides a challenge to user support Toolbars can hide behind things and can get pushed off screen People like to move things around to fit their personality or organizational structure Closed – Open – Left/top/bottom/right

ArcMap uses “Context Menus” to organize options and commands Context Menus are accessed by clicking the right mouse-button Shows those options that are valid within the context of the item the mouse pointer is over When you right-click on a Layer, only those options valid for layers are displayed Almost every item in ArcGIS has a Context Menu Get into the habit of right-clicking on things you see, you’ll be surprised at what you can find! Arcview 3.3 also had context menus – right click Show them we can get different context menus depending on where we click on the page – difference between View Document and Layout Document, TOC, Map area. Tell them use context menus by always right-click. They are very handy.

For instance, the Context Menu for a layer in ArcMap has only those options that relate to what you can do with a layer

As we go through this class you will be introduced to some of these toolbars and context menus There are just too many to go through them all – you have to explore The use of Context Menus will be stressed during the exercises and demonstrations

In ArcMap work is saved in a file called a Map Document (MXD extension) Create new, open existing, and save documents from the File menu and/or the Standard Toolbar Map documents store references to data but not the data itself Map Document is equivalent to Arcview 3.3 Project window. Map documents stores references to data just like Arcview 3.3’s Project window did. It does store graphics and labels will be stored in here. You do have option to save Annotation as well – later more about annotation. You can read Arcview 3.3 project file via software like Microsoft Word, Word, Notepad program since it is just a text file, but you can not read ArcMap mxd document. As you see File menu looks like the File menu in Microsoft Suites.

Map Documents have a Property Sheet that can be set by the user File | Map Document Properties Used mostly for documentation purposes Good for storing helpful info regarding Map Document Can define how paths are store Absolute (save drive letter) Relative (don’t save drive letter) If you are creating a lot of ArcMap and creating ArcMap Document (mxd) and diligent about documenting your Map Document property, you can do search on Map Document. You do document File: Map Properties. You can create thumb nail – create a jpg. Why do you want to create a thumb nail? If you do, you can see the thumb nail sketch in Arc Catalog. Using relative drive when you wan to give the Map Document to somebody. Arcview 3.3 also had Project Properties sheet.

Data Frames Within the Table of Contents data layers are organized into Data Frames Displays a collection of layers drawn in a particular order for a given map extent and map projection Can have multiple frames but only one can be active Alt-Click to activate Data Frames have their own property sheet Data Frame is an equivalent to Arcview 3.3 View. You can have multiple data frames, but can have only one active data frame. The active data frame has bold text in the TOC in the Data View and in Layout View, you see the item highlighted – surrounded by doted lined box. How do we make a data frame active? Alt-Click OR right-click to get the context menu, then Select Activate. You can only modify an active data frame.

Layers: Spatial Data in ArcMap Layers are the graphic representation of spatial data in ArcMap In ArcMap, data displayed in a Data Frame are called LAYERS Layers are generated from vector and raster data sources (and others we’ll talk about later)

The Table of Contents (TOC) Layers draw in their TOC order from bottom up As you add data, ArcMap will automatically place rasters on the bottom, followed by polygons, then lines, then points Reorder the layers by selecting and dragging You can show, hide, rename, or remove layers Familiar checkbox for displaying data Multiple Layers can be Grouped Legends can be expanded and contracted The TOC is moveable/dockable In Arcview 3.3, when you add a theme, it automatically placed on top of the existing themes, but in ArcGIS, it is different. Use Control key to collapse and open the grouped layers & folders.

TOC Display Options Drawing Order Source Visiblity Selection

ArcMap has many tools for navigating and exploring data Most are found on the Tools Toolbar Interactive Zoom-in Interactive Zoom-Out Pan Zoom to Full-Extent Fixed Zoom-in Fixed Zoom-out Previous Extent Next Extent Select Feature Clear Selected Features Select Elements (Graphics) In Arcview, you can go back/forward to 5 previous views ( go back to the previous view) Identify Hyperlink HTML popup Measure Find Find Route Open Time Slider Window Go to XY Create Viewer Window

Exercise 1 – Introduction to ArcMap
Get familiar with the ArcMap Interface Tools, Buttons, Toolbars, Context sensitive help Learn the basic layer navigation tools Zoom, pan, previous, next Table of Contents display Collapse and expand legends

Data Frames: displays a collection of layers drawn in a particular order for a given map extent and map projection Create new Data Frames Insert | Data Frame Active Data Frame shows in Display Window Active Frame name is in bold Activate Frames Alt-Click Context Menu - Activate Open ArcMap and show students a blank Map Project. The default layers are Layers.

Data Frame Properties The Data Frame property sheet has a number of tabs that contain settings/ properties to define General Tab – used to define general characteristics of data frame Name and Description Map and Display Units Reference Scale (for labels) Rotation (of view) Label Engine Typically, data from counties, they tend to use the County Projection system, but ArcMap will reproject the on the fly. The data is not really project the data from county. Show Rotation function. Also show what changing the Display unit affect the scale.

The Data Frame Tab Defines the extent and scale of what is to be displayed Extent Automatic Fixed Scale – can’t zoom in or out, only pan Fixed Extent – Can’t pan or zoom Other Data Frame Extent used by Full Extent Command Define your own extent “Clip” to Shape Display data within the extent of an existing layer Great alternative to physically clipping data

The Coordinate System Tab Defines the coordinate system of this data frame All data (regardless of native coordinate system) will be projected to this coordinate system before display Normally should be set to NAD83 UTM Zone 15N (MN DNR standard projection) Most of you, this should be set for you by your GIS Coordinator who setup ArcMap. Important: If this is not set, ArcMap will take the coordinate of the first layer that you add to the data frame of ArcMap.

Can manually define the Data Frame coordinate system within the Coordinate Tab OR Get in the habit of adding one of the layers from DNR QuickLayers when you start a new ArcMap document. Data Frame will assume the projection of the first data added to a data frame!

Extra: Data Frame So, why is it so important to have the data frame’s coordinate system set? Assuming all the data layers you want to display have projection files (.prj), or you know their native projections and can define them, ArcMap will project the layers on-the-fly. For example, you’ve acquired some data from a county but their data is in a county coordinate system…ArcMap can recognize this and will project the county data on top of ours.

Grids Grids are drawn around Map Frames on a Layout for referencing purposes Three types of grids Reference (Indexing) Graticules (Lat/Long) Measured (Map Units - UTM)

Frames Frames are used to put borders around data Frames on a Layout Border Styles Background Fills Drop Shadows

Extent Indicators Point out where other Data Frames are Normally used in Locator maps Shows project areas in context within larger geographic areas “Main Map” Data Frame Extent

Working with Layers Layers Form the basis for work in ArcMap
Layers come in a variety of forms Feature Layers – Vector Raster Layers – Raster Datasets (images and grids) ArcMap can work with numerous data types Geodatabases Shapefiles Arc/Info Coverages Web Mapping Services Many image formats Layer is created from the data and has particular color and style assigned to it.

Working with Layers To add Layers From ArcMap (manually):
Add Data button File | Add Data menu option Context menu on the Table of Contents or on the display window From QuickLayers You can also Add Data from ArcCatalog by dragging and dropping… Click this to open ArcCatalog window

Working with Layers The Add Data dialog box
Has the Windows Explorer look and feel Shows “Connected Folders” If you don’t see a folder, you need to click on Connect to a folder button and “connect” the folder you want Only shows geographic data - Vector and Raster Uses icons to indicate data type (Raster, Poly, Point, Line) Slow when searching folders with lots of data Connect to a folder Connect Folder button is used to connect to the folder. Once the folder is connected via this tool, the next time you try to Add data, ArcMap will remember that connection/connected folder.

Working with Layers Add Data dialog box – Hints:
Use the “Connect to Folder” option for places you navigate to often You can disconnect the connection Folder and data are not deleted! Try to avoid browsing with this window– can be slow Use Connect to Folder instead

Working with Layers Icons are used to identify different data types
Polygons Points Rasters Lines Tables

Working with Layers Drag a Layer from ArcCatalog Windows to Table of Contents

Working with Layers Layers in the TOC:
Legends can be collapsed and expanded CTRL-Click expands or collapsed all layer legends Layers can be moved up and down the TOC Layers can be copied, pasted and removed

Working with Layers Layers can be merged into Group Layers

Working with Layers The Layer Context Menu Copy and remove layers
Open a layer’s attribute table Join and Link (relate) tables Zoom to the active layer Zoom to Make the layer visible Set the visible scale range Work with Feature Selections Label features Convert Labels to Annotation Convert Features to Graphics Export and manage Data (Convert to Shapefile) Save as a layer file Set Layer Properties Right-click on any of the layers in the TOC. Zoom in – covers smaller area Zoom out – covers larger area. Example: 1/ /100,000 Larger scale smaller scale Minimum scale for a layer is set to 1/100,000, then when the view document is 1/500,000, you don’t see that particular layer. Max scale for a layer s set to 1/24,000, then when the View document is zoomed into 1/20,000, you don’t see that particular layer. In Group Layer setting, group layer setting overwrite individual layer.

Working with Layers Layer Properties
In ArcGIS Layers have a number of properties that you can define Access Properties by: Double-clicking the layer of interest, or Right-click and then select Properties The General Tab contains basic information including the name and visible scale range

Working with Layers The Source Tab
Shows you the base data location and allows you to change it if needed If you see a red exclamation point next to a layer in Data Frame, this is where you can fix the problem. Also displays data extent Show students! Create a new project, add a theme, then save and close ArcMap. Start Explorer and move the theme that you added. Start ArcMap and show students what a red exclamation mark next to the layer in the TOC. Tip! We can go into the project and do search and replace the path in the map document. Start Arc Catalog. Highlight mxd file and right-click and select Set Data Sources option. In the Search and replace window, the path to the data. F5 - - REFRESH

Working with Layers The Selection Tab
Each layer can now have its own selection color or symbol Default is to outline the feature in Aqua Helpful in differentiating between selected features from multiple layers

Working with Layers The Display Tab
Allows you to control the way the layer is displayed MapTips show attribute values when you hover the mouse over a feature Control Layer transparency Setup Hyperlinks Exclude certain features from displaying If you can't see MapTips even after you've enabled them, make sure that the layer is turned on and the features in the layer are not hidden by features in overlapping layers. Setting Transparency – Makes your layer transparent – a bit different from the transparency of Arcview 3.3 e.g. Make Land Cover (raster) to transparent so that you can see the shaded relief as a background. Also work with Vector layer In ArcMap, you can halt redraw process by pressing any key or click on the screen.

Working with Layers The Symbology Tab Define legend symbology
Fiddle factor is quite high Can import legends from ArcView 3.x

Working with Layers Defining Symbology
In ArcMap there are tons of predefined symbology Select one or create your own Change the fill color Outline color More Symbols available The Symbol Selector is used for all symbol operations Defining Symbology Easy to create custom symbols Symbol Manager is extensive…

Working with Layers Legends Single Symbol Categories Quantities
Unique Values Quantities Used primarily on numeric fields

Working with Layers Category Legends
Select the Value field Use the Add All Values button to add all unique values to the legend Use Add Values button to add selected values to the legend Select a color scheme, or Select each color patch individually, or Select multiple symbols by holding down [Shift] or [Ctrl] When you change the Value field, you need to click on Add All Values. Usually you want to turn off <all other values>

Working with Layers Styles
ArcMap has very strong legend and symbolization capabilities for Raster and Feature Themes Many more canned symbols and colors available contained in Styles A style is a theme based collection of colors and symbols that help enable consistent cartography Tools – Styles – Style Managers

Working with Layers Styles – click on Style References in the layer symbol selector Tools – Styles – Style Managers

Working with Layers The Fields Tab
This property allows you to view the layers fields and their definitions Set the primary display field used for MapTips Set aliases Make visible or invisible Set the display format of numeric field data

Working with Layers Definition Query Tab
Set a query to define which features will be accessible/visible Uses a Query Builder (SQL - Structured Query Builder Language) <Field_name> <Operator> <Value or String> Try not to type in.

Working with Layers The Labels Tab
ArcMap has a robust labeling environment Specify the label parameters here Lots of options, ways of placing labels Labels are dynamic redrawn every time you zoom or pan You cannot move labels - ArcMap decides where all the labels are placed…

Working with Layers The Joins & Relates Tab
Join tables and define relationships between them

Working with Layers Image Layer Properties
Control how Raster layers are displayed Includes air photos, scanned maps and raster data sets No labeling option Tabs vary based on the data source Most tab content is the same Is it photo image or raster data? Will not see this if not working with raster data

ArcMap – Working with Layers
Can spend much time defining layer properties Labels, symbols, definitions etc. Layer Properties can be saved as a layer file and shared with other users (i.e. Quick Layers) .lyr extension Contains all of the instructions to reconstitute this layer Does not store data – only the definitions

Exercise 2 – Working with Layers
Create Data Frames and set properties Add Layers and set Layer Properties Create a Layer legend Set a Layer’s label properties Create a Layer file

Accessing DNR Data The DNR’s GIS data is stored in a structured fashion called a Geospatial Data Resource Site (GDRS) ArcMap users can access all DNR GIS data through DNR QuickLayers. Landview users can access same data catalog when swapping in layers

Accessing DNR Data The goal of QuickLayers is a single portal to DNR GIS data. ArcMap users should never have to hunt around for DNR data. DNR QuickLayers: Organize content by thematic class Provide metadata and status maps Achieve a standard look “right out of the starting gate” – most data is classified, labeled, and symbolized Access to Landview to quickly search/locate a place, then bounce back to that place in ArcMap

Accessing DNR Data Quick Layers for ArcMap is accessible from Customize | Toolbars Turn on the toolbar using the checkbox

Accessing DNR Data Quick Layers toolbar appears
You can dock the toolbar

Accessing DNR Data Topic Categories:
MNDNR Basic– organized by thematic class <USERNAME> Custom Allows you to create your own category/layer structure Use Copy/Paste buttons to copy layers from main catalog into your custom catalog

Accessing DNR Data Show metadata window Add selected data
Data Source Updater Copy Paste Delete Insert Layer File Insert New Folder Edit Selected Folder Report Bug

Accessing DNR Data View Metadata for Layers by expanding the QuickLayers window Links to the full metadata record Press the expand button to show or hide the metadata

Accessing DNR Data Thematic Categories are represented as folders
Each folder contains a number of Layers Layers are represented with a blue icon Double click layer to add it to ArcMap or use the add data button on right

Accessing DNR Data To Create a Category Insert New Folder
Give new folder a name

Accessing DNR Data To Insert New Layer Create new Layer button

Accessing DNR Data Can copy and paste from DRS Layers into Custom Layers: Use the Copy and Paste Layers tool, or … Context menu! Once you create a layer, that layer should not be moved. So, first establish a folder in your hard drive to store all your custom layers.

Accessing DNR Data Change or add GDRS locations
This is where QuickLayers will look for data Great for field work Once you create a layer, that layer should not be moved. So, first establish a folder in your hard drive to store all your custom layers. Prioritize GDRS Locations

Accessing DNR Data Data source Updater
For updating 9.3x (DRS) Map Document data sources to ArcMap 10 (GDRS) Automatically redirects your data sources for you Once you create a layer, that layer should not be moved. So, first establish a folder in your hard drive to store all your custom layers.

Accessing DNR Data QuickLayers Bug Reporter

Exploring Your Data Selected Feature Statistics
Linked to feature selection As selection changes, so do statistics

Exploring Your Data Selectable Layers Defined in TOC
Default = Everything is selectable Having every layer selectable can be messy and slow Click selection icon to toggle selectable

Exploring Your Data Selection options
Use these to help control selection tool behavior Selection color Selection tolerance Interactive selection characteristics

Exploring Your Data Can save the selected set of records to a new layer or shapefile Layer Context Menu Data –Export Data... Save All Features or selected features

Exploring Your Data ArcGIS has several cool tools for exploring your data: Spatial Bookmarks – a bookmark that is tied to coordinates rather than a URL New Viewer Window – Open additional display window at user defined extent and scale Overview Window – a window that allows you to view where you are zoomed into (like a locator map) Magnifier – a window that magnifies the area under the cursor without having to actually zoom in

Exploring Your Data Spatial Bookmarks keep track of where you’ve been – and want to go back to Create, Name, Edit and Zoom-To bookmarks Like a web bookmark, only location in nature Zoom to a place of interest and then use Bookmarks | create option

Exploring Your Data Overview window: use the Window |Overview menu option Red outline indicates where you are Uses the bottom layer in TOC for background so can be a little flaky

Exploring Your data Magnifier Window
Toggle between Magnifier and Viewer windows by right-clicking the triangle Viewer option shows a snapshot - can move a Viewer window the Viewer image stays the same

Exercise 4 – Exploring Your Data
Using the Find tool Creating and using Bookmarks Creating an Overview window Using the Magnifier window Using the Identify tool Using the Select tool

Working with Tables All Feature datasets have attribute tables
Every feature you see has an associated attribute record in a table Open a table by right-clicking on the layer of interest and selecting the Open Attribute Table option

Working with Tables Name of active table Fields and field names
# of records selected Show all or selected records

Working with Tables Select records with the mouse pointer along the left edge (on grey boxes) Active table. Other opened tables show as greyed-out tabs

Working with Tables Table Options Related Tables Select by Attributes
Switch Selection Clear Selection Zoom to Selected Delete Selected

Working with Tables Display Tips:
To hide a column, drag the right edge of the column to the left To make it visible again, double-click on the bold column edge, or go to Options | Restore Default Column Widths Double clicking any column edge will restore the default width

Working with Tables Options Button Find and replace values
Attribute Query Clear selected records Switch selection Select all records Add a field to the table Arrange table windows Turn All Fields On Restore Default Column Widths Related Tables tasks Create a graph Add a table to a layout Print Reports Export Table Set appearance of table

Working with Tables Field Context Menu: Sort fields Summarize Fields
ascending or descending Summarize Fields New table created Generate Statistics No table created Calculate field Values Calculate Geometry Freeze/Unfreeze Column Holds column in display while scrolling Delete Field – yes delete field! Properties..

Working with Tables Adding new fields: For numeric fields
Specify Field Name Specify Field Type Short Integer – Up to 4 digits Long Integer - Up to 9 digits (Use Double for longer than 9 digits integer) Float - 7 significant digits (use for field calculations) Double - 15 significant digits (use for field calculations) Text Date Blob – Binary Large Object GUID For numeric fields Precision = length of field Scale = number of places to the right of the decimal Note: Add/Delete New field outside of an edit session

Working with Tables To calculate distance/ area:
Add a new field to the layer’s attribute table (float or double) Right-click on field name and choose Calculate Geometry Select type and units of calculation preferred Click OK to appending table without being in edit mode Field will be calculated

Working with Tables Must repeat calculation once features are edited
Calculations can be performed on all or selected records (get into the habit of calculating all ) Process works for other desired calculations

Working with Tables Retrieving “Snapshots” of attribute data:
Statistics for numerical fields

Working with Tables Want an easier way to update general calculations for shapefiles? Use ArcToolbox! DNRtoolbox has General tools | Calculate area/perimeter/length Double-click the tool, then drag a layer from TOC into dialog (or click browse folder)

Working with Tables Summarize for text/date fields and to create synopses of large data sets Decide which field to summarize, and by what Adds a summary table to your TOC (i.e. Cause of fire by total acres)

Working with Tables Graphs easily changed
Incorporate into layouts and other applications

Working with Tables New table placed in Source tab of TOC
Opening new table shows synopsis Use summary tables to create graphs

Exercise 5 - Working with Tables
Sorting/resizing Statistics Selecting records Select by attribute (querying) Graphing Calculating geometry

Labels, Annotation and Graphics
ArcMap has powerful map graphic tools Placement of text, symbols and graphics is much improved – but there is much more to learn Need to know how these are applied in ArcMap to become proficient with them First, some terminology…

Labels, Annotations and Graphics
Labels: text that displays some field of an attribute table dynamically As you pan and zoom they are regenerated Labels are placed based on layer properties you cannot modify a single label Label placement properties travel with a layer file Linked to a feature If a features attribute value changes, so does the label You can set certain restriction of where to place labels, but overall, ArcMap DECIDES where labels are placed All the property was assigned to each layer.

Annotation: storing text as graphics Often converted from the existing labels, but can create a new ones Can manually change the properties for each label Once placed, they don’t move unless you move them Two storage options In you map document as map document annotation Best option if not much text and text used in one map In a geodatabase as geodatabase annotation Stored in special types of feature classes inside the geodatabase – good for text used in multiple maps Best option if text is numerous

Dynamically placed by ArcMap – no moving them Managed as a group Created for features in the Data View Linked to features For on-screen viewing or creating map books Save in a map document Annotation Static Managed individually May or may not be linked to feature Use to create high quality map output Save in a map document or geodatabase

Accessing Label Properties Layer Properties Individual layer properties Label Manager Icon on Labeling Toolbar Display and set all labeling properties for Layers in the Data Frame

The Labeling Toolbar Label Priority Ranking Label Weight Ranking Label Manager Lock Labels View Unplaced Labels Pause Labeling

Setting Label Properties Numerous methods for controlling label drawing behavior/conflict detection Label Priority Defines the hierarchy for drawing order of labels between layers Specify if labels overlap features

Label Weight Ranking Used to assign relative importance to labels and features. Only used when there is a conflict such as an overlap between a label and feature. By Default, features have a feature weight of None for label classes

Point Label Placement Predefined placement scheme Many schemes available Custom placement options Locations Angles Duplicate Labels options

Predefined point label placement schemes Place labels in one of eight standard positions 0 = off limits 1 = preferred placement 2 = medium 3 = lowest

Line label placement Orientation Horizontal = always placed atop line at a best fit location Parallel = straight and placed parallel to direction of feature Curved = follows orientation of the line at a best fit location Perpendicular = straight but perpendicular Position Above Line, On the line, or Below, Orientation and Offset Location – Start point of a line Duplicate Labels

Polygon label placement Placement options: Horizontal (try first) Straight Only place inside polygon Duplicate labels

Label visibility Controls label drawing at various scales If not defined, label visibility defined by layer visibility Labels are displayed between these scales

Locking Labels Locks size and position of labels in the current extent How? Label Toolbar | Lock Labels button Why? Redraws faster because label placement is not calculated No label movement when zooming in or out (remember that labels are placed dynamically) Labels are only created in the View extent

Converting Labels to Annotation Automatic Placement doesn’t always work When individual labels need to be moved or have individual properties Annotation is choice for high quality maps where label placement is critical (“fine –tuning”) Automatically place labels, then convert to Annotation and adjust what you need to

Converting Labels Store annotation In a database In the map Create Annotation All Features Features in Current Extent Selected Features Unplaced Labels By default, unplaced labels are not converted to the annotations.

Control Annotation in the Data Frame Properties Convert to map document annotation: Where to store? All features or Features in current extent? Name the annotation group or take the default Click “Convert”

Annotation converted to geodatabase Locate or create a geodatabase to store geodatabase annotation To Create a File Geodatabase: Start ArcCatalog Create a file geodatabase and name it (gets a .GDB extension) in ArcCatalog Right-click Layer name and choose Convert to Annotation in ArcMap’s TOC.

Geodatabases are: A file type in ArcGIS Collection of geographic datasets of various types all under one folder such as Tables Feature Classes (points, lines, polygons, annotations, dimension, multi-patches, multi-points) Raster datasets Non-spatial data

Several types of geodatabases: File Geodatabases = stored as folders in a file system. Each dataset is held as a file that can scale up to 1 TB in size. Recommended over personal geodatabases. Personal Geodatabases = all datasets are stored within a Microsoft Access data file, limited to 2 GB. ArcSDE Geodatabases = stored in a relational database using Oracle, Microsoft SQL Server, IBM DB2, or IBM Informix. These multi-user geodatabases require use of ArcSDE. Unlimited in size and numbers of users.

More information about geodatabases in ArcMap Help system (type “overview of geodatabase”)

Once annotation is created, it can be edited Use Select Element tool, double-click text to edit

Graphics = shapes you draw on Data or Layout View(s) using the tools in the Drawing tool bar: Not spatial data Can be cut/copied/pasted to and from ArcGIS Like graphics in most windows programs: Nudged Aligned Distributed Flipped Can place text using the Text tool

Many of similar operations used to create spatial data (shapefiles, geodatabases) may apply: Union Intersect Remove Overlap (aka Erase) Subtract Like annotation, silimar tools and principles may apply

To create graphics: Draw graphic using the drop-down Drawing button of tools Use Text tool for text graphic Use Select Elements tool to move, resize, otherwise edit the graphic If drawing a freehand line or polygon, use edit line or polygon buttons to show vertices and move/add/delete them

Exercise 6 – Labels, Annotation, and Graphics
Labeling Setting a scale range Create a labeling expression Changing label symbology Converting labels to annotation Selecting elements Editing elements Challenge – Geodatabase annotation

Working with Layouts ArcMap has two presentations:
Data View = ad-hoc data exploration Equivalent to a View document in ArcView 3 Can have multiple data frames within the Data View Layout View = map creation Equivalent to a Layout document in ArcView 3 Unlike ArcView 3, can’t have multiple Layouts (but can have different Data Frames you drag in and out of the paper margins) Switch Views using the buttons on the lower part of the view window; otherwise use View: Data View/Layout View

Working with Layouts Two Data Frames
Layout View: A piece of paper with Data Frames Two Data Frames

Working with Layouts Setting Page characteristics:
File | Page and Print Setup option

Working with Layouts Layout View has two navigation toolbars:
One for the map (Tools tool bar) – work on a data frame: One for the data (Layout tool bar) – works on a page You can zoom and pan data in the layout to get it positioned just right A great feature - allows fine-tuning the Data View placement on the map

These work on the Data Frame, not the page
Working with Layouts These work on the Data Frame, not the page These work on the Page, not on the data

Working with Layouts Cartographic Elements
Inserted into the Layout View using Insert | menu In ArcView these were tools and in a menu . . . Titles Text Neatlines Legends North Arrows Scale Bars – Graphic Scale Bars Scale Text – 1:24,000 Pictures – bitmap, jpeg, gif, etc.. Objects – (Word Documents, Excel Spreadsheets)

Working with Layouts Cartographic Elements
Inserted Cartographic Elements are placed in map center Move/resize it to be where you want Text when placed can be hard to see!

Working with Layouts All elements placed have properties (right-click with a select element tool) Use Select Elements tool to select, resize, or move objects Delete using [del] key Double-clicking or right clicking on the objects to access their properties

Working with Layouts Graphic Element Context Menu
Many familiar options related to graphic operations Use for the cartographic elements that are selected light blue)

Working with Layouts Legends have myriad options, and they can be edited after they are created

Working with Layouts Legend Properties to change: Title Symbology
Spacing Frames, backgrounds Items to include Columns Classes Patch/label order Grouping Double click legend to change any property

Working with Layouts Want to change what shows up in the legend?
Go to Layer Properties

Working with Layouts but can also change how classes are displayed in Legend Properties using Style button

Working with Layouts Printing Layouts Just like other programs:
FILE | Print Print button Print Preview option PDF - For quick portable, scaleable, “GIS-like” maps where layers can be turned on and off, choose Export Map | Save as PDF

Exercise 7 – Building a Basic Layout
Printer and page setup Inserting map elements Creating a legend Adding additional Data Frames Navigating in the Data View and the Layout View Exporting maps
