building, editing, and displaying map documents
ArcCatalog
creating, importing, and maintaining map files
ArcToolbox
geoprocessing and spatial analysis tools
Other platforms included in ArcGIS Desktop are ArcScene and ArcGlobe
both enable 3D data viewing and manipulation

4. What we Cover Today? How to Use ArcCatalog 10x Open and Save document
Work with layers
Navigate in document
Measure distance

Work with attribute tables
Label features

5. Tutorial 1-0: How to Use ArcCatalog
Getting Started With ArcCatalog
What is ArcCatalog
ArcCatalog Window
Contents of the selected item on Catalog Tree
Catalog Tree
Together ArcMap, ArcCatalog, ArcScene, and ArcGlobe make up ArcGIS Desktop--- World’s most popular GIS software.
ArcCatalog is a GIS application that allows you to manage (find, preview, document and organize) your spatial data. It is similar to Window Explorer that let you browse the map data, and add data to ArcMap with ArcCatalog.

6. Starting Arc Catalog Click on the Start menu Click on ArcGIS
Click on ArcCatalog
contents, preview and metadata: These three tabs allow you to view more information about the files.
Content: lists the items contained by the selected item in the Catalog tree.
Preview: lets you see the geographic or attribute data it contains.
The Metadata tab lets you see documentation describing the item’s contents.

7. Connecting to a Folder
On the toolbar menu click the ‘Connect to Folder’ button
Navigate to a folder where your data is saved
Click the folder you would like to connect
This connection will remain there until it is disconnected

8. Tutorial 1-1: Open and Save a Map Document
Launch ArcMap
Open an Existing Map Document
Save the map document to a new location
Familiarize with the Tools
MyExercises\Chapter1\Tutorial1-1.mxd
Open ArcMap either from Start menu or through ArcCatalog .
The ArcMap interface includes a map and a table of contents that lists the map’s layers.

9. Summary of Toolbars Main Menu
Open other menu buttons as well and explore their content.

10. Customize

12. Tutorial 1-2: Work with Map Layers
Add and remove map layers
Turn a Layer on and off
Save map sing Relative Paths
Drag and Drop a layer from the Catalog Window
Change a layer’s display order
Change a layer’s color
Change a layer’s outline color
We will also discuss why this is required?
ArcMap displays map layers from a map document but the map document does not contain copies of the map layers. The map layer files remain external to the map document wherever they exist on computer storage media.
TOC : Map layers
Relative Path: When you add a layer to a map, ArcMap stores the paths in the map document. When you open a map, ArcMap locates the layer data using these stored paths. If ArcMap cannot find the data for a layer, the layer will still appear in the TOC, but not in map. Instead, ArcMap places a red exclamation mark (!) next to the layer name to indicate that this path needs repair.
Paths can be absolute or relative. Relative paths in a map specify the location of the layers relative to the current location on disk of the map document (.mxd file). Relative paths do not contain drive letter names, they enable the map and its associated data to point to the same directory structure regardless of the drive or folder in which the map resides.

13. Tutorial 1-3: Navigate in the Map Document
