Hey yall, I have a question regarding a new warning.
I do a good bit of flights for a university I work for. I've been helping monitor construction progress in a specific area, obtaining new imagery ~once a week. The drone is a Mavic3E, and I use flighthub 2 to setup and run all the flights, if that's relevant. I then process these images in Drone2Map. I have flown this particular area twice before and successfully produced orthophotos for those flights.
I recently updated Drone2Map to 2024.1. Upon attempting to process my newly collected imagery, I am met with the error: "flight altitude accuracy below expected threshold," when I attempt to start processing.
Upon checking my images, the altitudes collected are all as they should be, with the maximum variation in range coming out at ~2.0 meters or less. I believe this to be reasonable for my project. Images were all successfully taken with RTK, connected to the university's NTRIP profile.
I believe this to be a new aspect of Drone2Map 2024.10, but I was unable to locate the relevant changes in Esri's release notes, found here: https://doc.arcgis.com/en/drone2map/latest/get-started/whats-new.htm
I also see a new option under Options--Adjust Images to create an elevation surface, which I don't see mentioned in the release notes either, though this could be from a previous update I had not yet installed. I have this disabled for this project.
I am curious as to why I am receiving this error, when I would personally deem my obtained altitude values as both precise and accurate, relevant to my theoretical value. Is there a specific range that Drone2Map considers excessive for variance in altitude between images, or another reason unbeknownst to me that results in this error? I am only seeking to produce an orthophoto, so this shouldn't even be a big deal as far as I know, but I am aware that I have much to learn.
Thanks in advance for the help.
