ArcGIS Desktop

• ArcMap – explore and edit geographic data, analysis, create maps/reports (map document files .mxd)

• ArcCatalog – browsing, managing, documenting geographic data

• ArcToolbox – tools used for GIS analysis, data management, data conversion

• Metadata –info that describes or documents a geographic dataset (data about data)

Scale• Scale is the relationship between the size of features on

a map and the size of the corresponding objects in the real world. Scale is commonly expressed as a ratio, or representative fraction, such as 1:24,000. This scale means one unit on the map is equal to 24,000 units on the earth. Another way of thinking about it is that the objects on the earth are 24,000 times larger than the features on the map which represent them.

• Large-scale map such as a map of city streets or a building plan, covers a small area in more detail.

• A small-scale map, such as a world map, covers a

large area in less detail.

• GIS maps are dynamic—you can change the scale to see more or less detail as desired.

Buffer

• Creates Buffer polygons to a specified distance around the Input Features

Buffer

Union

• Creates a geometric intersections of the Input Features.

• All features will be written to the Output Feature Class with the attributes from the Input Features, which it overlaps.

• In terms of a table, want both irrigated area and county name.
