Ouch == bitten by a bug in Trimble Access
Bugger
Got caught by a subtle bug in Access today.
Adjusting the pole height of a gps observation will change the height for that observation,
But it does not alter the height of an averaged point derived from that observation.
I changed both shots on a control point, but a later resection used the unchanged averaged position
The net effect is that the house foundation is now 400mm too high
Sigh 🙁
