Normally, how fast a land surveyor can do it? Traditionally method, we need to look for boundary marks at the lot or neighbor lot to prove the datum and perhaps some details survey before declare the position. I think it may take 1-2 hours if the marks easily found at the lot. Most of the time, boundary marks are missing and cause the land surveyor need to find more boundary marks for datum. It is time consuming.
In this case, TSM (Title Survey Module) with the handheld GPS is the cheaper solution to identity the position without searching for the datum. We just enter the PA data into TSM and this program has capability to convert the WGS long/lat into cassini-solder coordinate system.
When you reach at the site, on the GPS system and a Red Cross will appeal in TSM system. The Red Cross will follow where we walk and it is tracking us. The system is easily to operate without much knowledge in transformation coordinate.
The tracking system is no accurate as normal survey ( maybe up to 2-3 meters) and it depends on the total of satellite receive during that particular periods. However, this application is good enough to serve this purpose.
Thus, land surveyor must smart in choosing the tools to meet the client requirement.
