Can anybody describe the Method of Demarcation of lease Pillar From FRP By commonly Used garmin GPS 72H
I study a Mine Lease map and practically do this Job by GPS 72H.
For example FRP to A pillar 250 meter and 25 degree with north.
i go field and start the GPS and record the latlong of FRP ,like back bearing is 25+180=205 deg .
we go the menu option and see the record frp number .and go to the Existing A pillar along see the FRP Number .the degree is match and length is also match ,ok
but i found that this location is pillar is mid center of 205 degree( 204 to 205 -205 to 206)
204 to 205 i.e. is that where 204 is over and 205 deg is start
205 ti 206 i.e.is that where 205 deg is end and 206 is start
for figure show
..............................................205 End
..............................................Pillar A location
..............................................205 start
My Question is that Firstly that it is right method or BUt common sense is that Pillar A location is 205 deg 30minute
how can judge 205 degree and 205.5 degree
