We recently demo'ed a Topcon image station.
Don't think we will purchase it but one thing I loved was the ability to outline an poygonal area and scan within the polygon at a predetermined Hor. and Ver. interval.
If this was a routine that could be added to Surv CE it would allow any LR robotic instrument to be able to do a grid scan.
I feel this would be a valuable function and on the face of it would not seem to be too difficult for someone who is familiar with these things.
