U.S. Bureau of Reclamation's Remotes Sensing and GIS Group, Denver, Colorado Unpublished Material vector digital data CD-ROM 1999 2003 ground condition Accuracy Assessment Points Unknown Points were located using a stratified random sampling method. Portions of the methodology were derived from the USGS/NPS Vegetation Mapping Program's Accuracy Assessment Procedures. Vegetation data at each point was recorded by qualified ecologists using a standard NVC Point data collection form. Data was manually transferred to a MS Access database. Point coverage was created by importing the database into ArcView as an event theme. Unknown Dan Cogan Bureau of Reclamation Physical Scientist mailing and physica address
