ArcGIS is an integrated collection of GIS software products that provides a standards-based platform for spatial analysis, data management, and mapping. It is made by Environmental Systems Research Institute, Inc. (ESRI) a company based out of Redlands, California. ESRI is one of the global leaders in the GIS software industry. "ArcGIS technology is a platform for building a complete geographic information system (GIS) that lets you easily author data, maps, globes, and models on the desktop; publish them to a GIS server and/or share them online; and use them on the desktop, on the Web, or in the field." . ArcGIS enables a person or corporation to perform spatial analysis in a more effective way than has been seen in the past. ArcGIS combines multiple elements of ESRI’s GIS software in order to allow users to create and distribute GIS. "The ArcGIS desktop products include ArcReader, which allows one to view and query maps created with the other Arc products; ArcView, which allows one to view spatial data, create layered maps, and perform basic spatial analysis; ArcEditor which, in addition to the functionality of ArcView, includes more advanced tools for manipulation of shapefiles and geodatabases; or ArcInfo which includes capabilities for data manipulation, editing, and analysis." .
