Photogrammetry Survey Capabilities
Photogrammetric methods can now be used to produce survey maps that meet the standards of the American Land Title Association (ALTA). An example of such a service that Sidwell performed is Scott Air Force Base in Southern Illinois. As part of a plan to privatize the military housing there, Sidwell was contracted to secure aerial photography and collect planimetric data for an ALTA survey of the subject property immediately following construction of new housing units. Sidwell continues to utilize this technology to assist surveying of properties and other features on the earth’s surface.
