ArcGIS 9 Desktop (ArcView, ArcEditor, and ArcInfo) includes a completely new environment for geographic data processing and analysis (geoprocessing). The new geoprocessing framework includes ModelBuilder, an interactive and visual application for creating and executing process models; a sophisticated scripting environment; and an intelligent command line interface. The combination of powerful tools and flexible working environments enables users to select the technology that best supports their natural work flows and application requirements.
