OR/WA BLM 05/2008 vector digital data This theme shows the Wilderness Study Area boundaries as inventoried in the mid-1980's and precisely defined in the Oct.1991 "Wilderness Study Report" and/or on USGS 7.5 minute quad maps. There have also been a few changes to WSAs since the 1991 report. WSAs are essentially roadless areas under BLM jurisdiction. WSAs have special management restrictions and priorities.

There are several factors to consider in GIS error: scale and accuracy of map-based sources, accuracy of GPS equipment, and the skill level of the data manipulators. A value of '0' indicates no entry was made. This is the correct value when the COORD_SRC is another GIS theme (DLG, GCD, DEM) because the accuracy is determined by that theme. If COORD_SRC is MAP or GPS, however, a value of '0' indicates a missing value that should be filled in either with a non-zero number or '-1'. A value of '-1' indicates that the accuracy is unknown and no reliable estimate can be made. Bureau of Land Management Attributes are provided that give basic information about source, type, and accuracy of the line data.
