1. ArcGIS ArcCatalog, ArcMap and ArcToolbox

2. ArcCatalog • ArcCatalog let you • Find • Preview • Document • Organize geographical data • Create personal geodatabase to store that data • Create and import feature classes and tables • View and update metadata • Drag and drop data onto an existing map in ArcMap

3. ArcMap • Create and interact with maps • View, edit and analyze geographic data • Query spatial data • Symbolize your data • Create charts and reports • Map layouts • Support wide variety of data format (shapefile, coverages, tables, CAD drawings, images, grids, and triangular irregular network)

4. ArcToolbox • GIS geoprocessing tools

5. ArcGIS Feature Classes, Data File Formats in ArcGIS

6. Feature Class • A single geographic feature type (having the same spatial representation) corresponds to a feature class • Feature classes in geodatabase are: • Point feature class • Line feature class • Polygon feature class • Annotation

7. Feature Classes

8. Data File Formats and ArcGIS • Shapefile - legacy ESRI (ArcView 3.x) • Coverage - legacy ESRI (ArcInfo 7.x) • Geodatabase - most recent (ArcGIS 8.x onwards) • Layer Source: http://www.indiana.edu/~gisci/courses/g338/lectures/introduction-to-gis-2.html

10. Shapefile (.shp) • Each shapefile corresponds to a feature class • A complete shapefile comprises of at least 3 files with the same prefix name( *.shp, *.shx and *.dbf) (should be saved in a same folder) • Geometric information displayed in ArcCatalog's "Preview” • Attribute information displayed in ArcCatalog's "Table Preview" http://www.geog.ucsb.edu/~jeff/gis/data_models1.html

11. ArcInfo Coverages • A coverage is a collection of files in a subdirectory • Contains multiple geographic feature types • Folder that contains all of these feature classes is the actual coverage • Two folders within a workspace (one with the name of the coverage and another named ‘info’) • Geometric information displayed in ArcCatalog's"Preview” • Attribute information displayed in ArcCatalog's "Table Preview" http://www.geog.ucsb.edu/~jeff/gis/data_models1.html

12. ArcInfo Coverages

13. ArcInfo Coverages In Class Exercise • Question:1- Use ArcGIS Help to find "coverages" to answer the following questions. • List any 3 feature classes that a coverage can contain. • What are tic points?

14. Geodatabase (.mdb) • Primary mechanism used to organize and use geographic information in ArcGIS • Geodatabase is a collection of geographic datasets of various types (vector, raster, and tabular data) • Can be created, accessed, managed through standard menus and ArcCatalog, ArcToolbox and ArcMap

15. Geodatabase http://www.geog.ucsb.edu/~jeff/gis/data_models1.html

16. Layer File (.lyr) • Readable directly by ArcGIS • Does not contain actual geographic data • Specifications for the presentation of other datasets • color • label properties (font, color, placements, etc.)
