has performed GPA
and GIS surveys
throughout the country for over 12 years. We presently have ten GPS receivers
and can routinely do very precise static control, Real Time Kinematic
(RTK), and Geographic Information System
. We have performed this kind of work for federal
and local governments
, private developers
, utility companies
, and many other surveying
and engineering firms
We have spent considerable time in developing procedures and techniques to allow us to collect large amounts of very accurate mapping information at very low costs - so much so that our mapping acquisition results are often cheaper than present day photogrammetric and digitizing methods and are 10 to 30 times more accurate. We stay current with the changes in how GPS/GIS information can and should be used.
In our present contract with Prince William County, VA, we are establishing a High Accuracy Primary System of Monuments with six mile spacing, instead of a much denser, less accurate and much more expensive network. Additional documentation will be added when needed and can be partially funded by developer fees.
