Surveying is important for those with an interest in obtaining the specifications of land or property. All governments require surveying. Private interests include those who want to purchase or sell land. Surveying companies now use gps land surveying equipment to ease the task of surveying. SurveyorCentral.com has specific software packages, similar to other companies, for improving the process of surveying.
Land surveying software connects with the triangulation process provided by GPS coordinates. Signals from a certain point are sent up to a GPS location satellite. The internal computer or calculating software is able to receive signals from the satellite that has also received signals from at least two other satellites in the communication chain. The internal computer is able to use the information from the feedback signals to provide a read-out of the exact longitudinal and latitudinal positions.
Many varieties of land surveying software use real time kinematic navigation from satellites. RTK GPS involves the real time lining up of signals between two satellites to get the exact match-up that would reveal a location. A base location, used by the surveying company, provides a carrier or correction signal that mobile units can match to determine their locations. Some companies use dual frequency GPS. They receive signals with a Glonass RTK receiver.
Surveying software helps land owners solve problems dealing with easement lines needed for utilities. Prospective buyers of land would want to know if the property exists on a floodplain. These are some of the many uses for RTK GPS.
