The USGS grid was scanned from a wall map. Good alternate if there is a gap
in the BLM data, but with less accuracy. Provides full coverage of all townships,
but does not have sections or quarter-quarter sections. Calculates area, centroid,
and corner points. You must zoom into the central or western United States
to see the data.
Hint
In mountainous areas it might be helpful to turn off the terrain layer in Google
Earth. Otherwise, the survey grid can look distorted as it shapes itself to
the earth's surface.
