- 14. ArcGIS Software • ArcGIS is composed of applications and extensions at three license levels. The applications include ArcMap, ArcCatalog, ArcScene, and ArcGlobe, and the extensions include 3D Analyst, Network Analyst, Spatial Analyst, Geostatistical Analyst, and others. The license levels of Basic, Standard, and Advanced determine the number of tools a user can have for data analysis, data editing, and data management. The core applications for ArcGIS are ArcMap and ArcGIS Pro.
- 15. Components of Arc GIS • ArcMap: ArcMap is the primary application used in ArcGIS and is used to perform a wide range of common GIS tasks • ArcCatalog: The ArcCatalog application provides a catalog window that is used to organize and manage various types of geographic information for ArcGIS for Desktop. • ArcScene: ArcScene is a 3D visualization application that allows you to view your GIS data in three dimensions. • ArcGlobe: ArcGlobe is a 3D visualization application that allows you to view large amounts of GIS data on a globe surface.
