Division 4 (Gunnison Basin) GIS data sets are available for download and can be used directly in ArcGIS. Map Viewer
is a free web-based tool available to users and does not require ArcGIS.
GIS data layers are available as ESRI file geodatabases, compatible with version 10.1 and later. Point features have been generated from the most recent HydroBase database by division and major data type. Data coordinates are in the UTM Zone 13 (NAD 83) projection. Polygon and other layers in some cases have been collected from other sources. Features generated from HydroBase contain only the minimum attributes for the data type.
