Digital Land Grid
Supported by on-the-ground monumentation, is the most
accurate product of its type available today. Available in most geologic and mapping formats.
- Many sources are used for Topographic's Digital Land Grid
development including USGS 1:24,000 topographic quads, aerial photography
and documentation on thousands of corners found from over 35 years of
surveying in Texas.
- Specific procedures are followed in building the
land grid such as establishing and researching monumented control points,
having our registered surveyors and cartographers draw the section, block
and survey lines on the geodetically accurate USGS quads, verifying section,
block and survey names of each tract, and digitizing and assigning a control
quality level to each point.
- Updates and revisions are always available. When
differences or discrepancies between the digital land grid and the on-the-ground
control are found by our field crews, the correct information is noted and
updated in our database. The building of a correct and accurate
base map of Texas sections, blocks, and surveys is a long term continuous
process.
