PronghornPerennialWater is an ESRI SDE Feature Class showing Perennial
Water Sources for Pronghorn Antelope. Perennial Water is defined as
sources of water known to be important to antelope survival in late
summer or other drought periods. A four-mile radius should be described
around a point source and four mile band be drawn along a river or stream.
This information was derived from field personnel. A variety of data
capture techniques were used including drawing on mylar overlays at
1:50,000 scale USGS county mapsheets and implementation of the
SmartBoard Interactive Whiteboard using stand-up, real-time digitizing
at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing
Mapping Resources. GeoWorld 16(3):32-35).
Dataset was acquired from a third party distributor who obtained it from CDOW in January 2011. The authoritative data source is available on ArcGIS.com (http://www.arcgis.com/home/item.html?id=658ca28f48d4451f9eb4d60e3e9b573d) and will be updated from that location.
