WhiteStar's Texas Land Survey is a seamless, high-resolution database of county boundaries, blocks, surveys, abstracts, subdivisions, lots, and tracts that is ideal for base maps and plotting land ownership and leases. The Texas Land Survey precisely overlays USGS Digital Orthophotos and Digital Raster Graphs, making it useful for indexing and analysis.

Data Source
WhiteStar's Texas Land Survey is based on official, researchable state records from the Railroad Commission of Texas. The original General Land Office surveys for 254 Texas counties were drafted onto USGS 1:24,000 series maps by the Texas Railroad Commission.

Enhancement
Using ESRI GIS technology, WhiteStar has digitized the survey lines and created polygonal coverages with attributes and map-friendly annotation. The resulting data are seamless across state and county boundaries and have cleaner lines, layers, and annotation than the original Railroad Commission data.

We offer two versions of the Texas Land Survey data: vector - clean lines with annotation optimized for display and polygonal - attributed polygons optimized for well spotting and GIS queries.

Content
Data layers include County Boundary, Block, Survey, Abstract, Subdivision, Lot, Tract, Overlap Block, Overlap Survey, Overlap Abstract, Overlap Subdivision, and Overlap Lot. Subdivisions, lots, and tracts are available in attributed polygonal format only from WhiteStar. Tabular attributes include block, survey, abstract, subdivision, lot, and tract name and number.

Format
The Texas Land Survey is currently available in the following formats:

Coverage
Complete State of Texas coverage, available by county or state.

Application
Land mapping, oil and gas exploration, pipeline mapping, agriculture, forestry, parcel mapping.
