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.
•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
