Get the answers you need quickly with WhiteStar's comprehensive Lot, Tract and Special Survey Data.

Data Source
WhiteStar's Digital Sub-section survey data is digitized from the Bureau of Land Management's Official Surveys and then georeferenced to WhiteStar's Public Land Survey Database. These Data adhere to the National Map Accuracy Standard for a 1:24,000 scale quadrangle of +/- forty feet.

Enhancement
Using ESRI GIS technology, WhiteStar has created polygonal coverages with attributes and map-friendly annotation. All Lots, Tracts, and Special Surveys are attributed with official BLM acreages where available and geometry honors the official survey of record. The resulting data are seamless across state and county boundaries and have clean polygons, layers, and annotation. The data can be displayed as annotated polygons, but are also optimized for well spotting, land management, and GIS queries.

Content
Data layers include Township, Section, Lot, Quarter Quarter, and Tract Boundaries. Tabular attributes include meridian, township, range, section number, survey type, survey number, survey name, aliquot part, BLM acreage, and patentee name.
