Cadastral Survey
 

Data Services  Land Survey 

  

Cadastral survey requires high accuracy over relatively short baselines.  We have implemented an RTK (Real Time Kinematic) system, based on three of Ashtech Z-Surveyor dual frequency, 12 channel, differential mode GPS receivers.  

The GPS receivers are joined via a VHF data link and in this mode, we regularly obtain sub-centimetre accuracy with observation times of less than 30 seconds.

For urban areas where the GPS coverage can be interrupted (with the need to re-gain phase-lock), we supplement observations with SOKKIA Total Stations.
