The objective for Walk Through a GNSS Survey is simple – walk through the steps to do a survey with TPC and a GNSS RTK receiver.
•each step has a short video – some are a little longer
•we used an emlid Reach RS2+ GNSS receiver - see Emlid (CSV).
•see how TPC does common tasks like recalling points
We selected a simple GNSS survey where we find and mark the property corners and set a few points on line so the owner can build a dog fence. We chose this example because it’s simple to understand, letting us focus instead, on some of TPC’s key concepts.
Introduction (1:51)
•Find existing property corners and set points on line so owner can build a dog fence.
•Est $500 to $700 depending on corner search time
1: Research (3:20)
•Address – Google Maps
•Visual – Google Earth via address
•Tax lot map – verify location
•Surveys – get all lot dimensions
2: Record Data / Corners (12:11)
•Enter block into TPC to get record locations for all lot corners
•Create one traverse
•Use Space Bar to repeat direction
•Edit Traverse View as needed until it closes – look for mistakes
3: Corner Search / Ties (8:46)
•Talk to neighbors – start at lot 20 pin
•Tie them as I find them
•North side pins – several disturbed
•East side pin – neighbor showed me where it was
•South side pins – GNSS issues
4: Survey Calibration (7:25)
•Default – use only fixed
•Evaluate – RMS float vs fixed
•Calibrate and check via stakeout report
5: Survey Decision (4:07)
•Use found monuments not record corners
6: Export Lines via DXF (5:06)
•Emlid flow needs lines to stakeout points online, but doesn’t have a tool to create the lines
•So we export the lines as a DXF from TPC to emlid
