This is my first experience with GPS surveying and I don’t think it’s gone well. I used 2 Reach units (base & rover) to collect the location of GCP’s for a drone survey of an area, went back a month later and did the same thing.
I am looking to find elevation difference in the DEM’s but they are 5-10m in height and I should only be seeing centimeters of change (although they seem to be laterally accurate).
Obviously I must have done something pretty wrong, as I said I was navigating this process rather blindly, I am hoping that someone could help me start from the beginning and salvage some usable data.
-I did not have the correct settings for the first survey and no longer have access to the units, are they recorded in any of the output files?
-Using RTKpost I entered the .obs files for the base & rover and the .nav for the base. I have what looks to be an accurate Ground Track when plotted as a KML in Google Earth, but how do I find only the data for Points I collected during the survey?
I would really appreciate any input or constructive scolding…
