Geodolite Network Measurements.
The red lines in the above map show lines measured between
two stations using the Geodolite. The blue dots represent stations in the network.
Clicking on a station will take you to a
list of all line lengths measured in this network.
The Geodolite is a single color laser used for
electronic distance measurements (EDM). Geodolite measurements
were conducted by the USGS from the early 70's through the early 90's
when crustal deformation began to be measured using the
Global Positioning System (GPS).
See Savage, J. C., and W. H., Prescott, Precision of Geodolite
measurements, J. Geophys. Res., 78, 6001-6007, 1973, for more
information about the Geodolite.
Disclaimer:
Be advised that these station positions are unchecked.
The station positions and line lengths are unchecked
and should not be used for any engineering applications.
Caveat emptor.
