Important notes

GTM PRO® is not a substitute for the work of a surveying professional. The program was developed to work with hand-held GPS receivers that have an accuracy of 5 to 10 meters after the removal of the Selective Availability (SA) by the USA government.

To obtain accuracy in area calculation, the hand-held GPS receiver is not the most appropriate instrument to use. That kind of accuracy will only be obtained by contracting a professional who uses equipment which is more precise (and more expensive!) than a hand-held GPS receiver, such as Total Stations and Differential GPS.

The program is not intended for those works that demand accuracy less than 10 meters or 3 meters where WAAS/EGNOS is available, as land demarcations and appraisal of small urban areas. Topographical works with altitude must be accomplished with caution, because the altitude error of the hand-held GPS receiver is up to 3 times the horizontal error.
