Improving drone map alignment using OPUS

One of the biggest challenges with drone data is getting imagery from multiple dates to line up correctly, or in other words to get it coregistered. Coregistration is relatively straightforward if you have some permanent ground control points or recognizable and unmoving objects in the scenes. But, in many situations, that's not the case. So, we need strategies for coregistering drone data from different dates that either uses only temporary ground control points or doesn't need any ground control points at all. In this video, we'll look at using NOAA's Online Positioning User Service (OPUS) to post-process our local GNSS base station data to get better positioning and, ultimately, better coregistration of drone map products. You can find OPUS and learn more about it at https://www.ngs.noaa.gov/OPUS/about.jsp OPUS is only one tool for correcting GNSS base station location estimates. Here's a list of some of the other tools: OPUS (US NOAA) - https://www.ngs.noaa.gov/OPUS/index.jsp CSRS-PPP (Natural Resources Canada) - https://webapp.csrs-scrs.nrcan-rncan.... AUSPos (Geoscience Australia) - https://gnss.ga.gov.au/auspos CenterPoint RTX (Trimble) - https://trimblertx.com/ Get detailed instructions for how to prep and use OPUS to process data from Emlid Reach GNSS receivers at https://uidronelab.org/2024/11/12/pos...
