ArcGIS is a geographic information system (GIS) for working with maps and geographic information.

It is used for:
  • Creating and using maps.
  • Compiling geographic data.
  • Analyzing mapped information.
  • Sharing and discovering geographic information.
  • Using maps and geographic information in a range of applications.
  • Managing geographic information in a database.
The system provides an infrastructure for making maps and geographic information available throughout an organization, across a community, and openly on the Web.

ArcGIS includes the following Windows desktop software:
  • ArcReader, which allows one to view and query maps created with the other ArcGIS products;
  • ArcGIS for Desktop, which is licensed under three functionality levels:
    • ArcGIS for Desktop Basic (formerly known as ArcView), which allows one to view spatial data, create layered maps, and perform basic spatial analysis;
    • ArcGIS for Desktop Standard (formerly known as ArcEditor), which in addition to the functionality of ArcView, includes more advanced tools for manipulation of shapefiles and geodatabases;
    • ArcGIS for Desktop Advanced (formerly known as ArcInfo), which includes capabilities for data manipulation, editing, and analysis.
