While direct measurements between positions in a network or boundary contribute to establish redundancy, it is not always possible.  Enter relative positional precision, set forth by the National Society of Professional Surveyors (NSPS) and adopted by the American Land Title Association (ALTA) for land boundary surveys.  Join this month’s TBC Power Hour to learn how to use the network adjustment routine in TBC alongside the NSPS/ALTA Relative Precision Report to compute relative precisions between measurements.  The primary application is for official ALTA boundary surveys in the United States and many State Standards for using GNSS in the course of boundary surveys, but this routine also provides a quality check between any set of measurements across GNSS, total station, and level sensors for TBC’s global users.
