Drones with precise positioning such as RTK/PPK are becoming common with those using them for mapping purposes. This leads to the question: how precise does positioning need to be to create accurate maps from photogrammetry? With options such as RTK and PPK, image location can be determined within centimeters. So, do these actually help to produce better maps? And how do you verify the accuracy of maps produced using this technology? Is there ever a time where GCP’s are not necessary? And can maps made without RTK/PPK enabled systems be as accurate as those with? Join David Alamillo and Eric Andelin as they discuss these options and go over the processing workflows for each.
Specifically, attendees will learn about the following:
- What is the difference between RTK and PPK
- How RTK/PPKs affect aerial triangulation
- When are GCPs needed
- How accuracy is validated
