Anyone have experience using this technology? i.e. field verifications of structures where you need to capture the lat / long of a house that is 1000 feet from the road with limited access.
Actually a pretty simplistic application of offset that was implemented early in the commercial GPS era by Trimble and Laser Atlanta.
Check out Laser Atlanta's "Advantage" line, or LTI's TruePulse line. The resulting az/elev/slope distance string provides "offset" from the GPS position collected at the laser head. Using offset the sample point position can be calculated in near real time with a hand held data logger. Or, the "offset" and GPS position can be combined and corrected after collection for more precise results.
Trimble's Pathfinder Office and TerraSync software packages excel at this processing flow.
This is a cheap alternative:
