Appropriate for use in local and regional thematic analysis. Data are not accurate enough to be used as a geodetic or engineering base.
not available
Digitized boundaries have not been verified. Boundaries from county plat books were digitized on screen against 1:100,000 coverages (e.g.roads, section lines, etc.)
Data set represents best attempt in a short time frame to include federal lands that were found in county plat books, known holdings by USFWS, and other general sources. This data set requires further work.
Polygon data are topologically complete polygons.
