METADATA FOR WRDAMS SHAPEFILE

Revised: July 21, 2004

The shapefile coordinate system is UTM zone 12. Many of the origional positions were scaled as latitude/longitude values from 1:24000 USGS Quadrangle series maps. They were later converted to UTM locations. Locations for recent additions to the database are either scaled from USGS Quadrangle maps, collected from GPS observations or converted from Public Land Survey descriptions to UTM coordinates.
