1. Introduction to ArcGIS

2. Goals Become familiar with ArcGIS ▫Locating and running the program ▫Introduction to the 3 ArcGIS interfaces ▫Experience with some of the basic tools in each interface Become familiar with GIS data ▫Data available on campus ▫Data available on the web ▫Accessing data in AFS and other network locations Introduce help resources ▫ATN GIS support ▫Davis Library ▫Other on campus resources ▫On-line resources

3. Agenda ArcGIS: What is a GIS? ArcCatalog ▫ArcCatalog Exercise ArcMap ▫ArcMap Exercise ArcToolbox ▫ArcToolbox Demo

4. ArcGIS GIS is the combination of tabular data with a geographic representation ESRI’s Premiere GIS software A scalable GIS system which includes ArcView, ArcEditor, and ArcInfo Provides a wide range of GIS tools for needs which range from Desktop mapping to Geostatistical Analysis

5. ArcGIS has a 3 part interface ArcCatalog ▫Navigating spatial data ArcMap ▫Creating presentation graphics ArcToolbox ▫Powerful geoprocessing tools

6. Data for ArcGIS Vector Data ▫ArcView shapefiles ▫ArcInfo coverages ▫Geodatase ▫CAD drawing Raster Data ▫Most common imagery formats can be read ▫ArcInfo GRIDs, MRSID

7. ArcCatalog ArcCatalog is similar to the Windows “explorer”, or the “My Computer” icon on your windows desktop. It is a tool for navigating through your GIS datasets. The benefit of using ArcCatalog is that it has been specially designed for use with spatial data.

8. ArcCatalog: Previews Using ArcCatalog you can easily preview both your spatial datasets, and the attribute data associated with them \\AFS\isis.unc.edu\data\gis\tutorial\beginner_exercise s for example.\\AFS\isis.unc.edu\data\gis\tutorial\beginner_exercise s

9. ArcCatalog: Spatial Search Within ArcCatalog you can easily search for data based on location and attributes stored in its metadata

10. ArcCatalog: Data Management ArcCatalog is provides an environment to cut and paste spatial data into new directories and geodatabases. Additionally, several common conversion routines are available from ArcCatalog.

11. ArcCatalog: Metadata (exercise 1) ArcCatalog includes tools for viewing and editing Metadata.

12. ArcMap ArcMap is like a virtual drafting table. It contains a canvas where GIS data layers are drawn, and a Table of Contents (TOC) which helps keep track of the data in the canvas. For desktop mapping, this is the interface which you will spend most of your time. The canvas can be viewed in two states: data view and layout view. There are several toolbars available in ArcMap. The standard toolbar contains basic file management tools. The tools toolbar contains simple navigation, identification, and selection tools. The draw toolbar is a basic windows style drawing toolbar. There are several other special need toolbars available from the View menu. Among other things, there is an edit toolbar and there are special toolbars for extensions available. In addition to the toolbars, there are several menus available in ArcMap. The menus contain some of the commonly used items from the toolbars as well as a few common functions from ArcCatalog and ArcToolbox.

14. Saving your work in ArcGIS (exercise 2) Map Documents (.mxd) ▫Saves your progress in ArcMap. Does not save GIS data, just references its location on disk. Layer Files (.lyr) ▫Saves symbology and other display properties for a data source. Again, the data source itself is not copied, but instead referenced by the layer file Map Templaces (.mxt) ▫If you are going to create several maps with a similar layout, the template can be a time-saving tool.

15. ArcToolbox For heavy duty processing, ArcToolbox contains analysis, conversion, and data management tools. One can construct custom tools. You may set up most tools using wizards to better understand otherwise complicated options.
