WhiteStar's
Public Land Survey is a
seamless, high-resolution database of Congressional Survey townships and
sections that is ideal for base maps and plotting land ownership and leases.
The Public Land Survey (also known as PLSS, Digital Land Grid, or Digitized
Section, Township and Range) precisely overlays USGS Digital Orthophotos,
Digital Raster Graphs, and Digital Elevation Data, making it useful for
indexing and analysis.
Data
Source
WhiteStar's Public Land Survey is digitized from USGS 1:24,000 series
topographic maps using a highly accurate spatial
averaging digitizing technique, which captures corner boundaries to
+/- 40 foot accuracies. The Wyoming resurveys are included and Carter
townships are used for Kentucky and Tennessee.
Enhancement
Using
ESRI
GIS
technology,
WhiteStar has created
polygonal
coverages
with attributes and map-friendly annotation. 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 and GIS queries.
Content
Data layers include Township and Section Boundaries. Tabular attributes
include meridian, township, range, and section numbers.
