Are maps created by the OpenDroneMap community catalogued anywhere? I may have missed the obvious answer, but only found docs about creating maps (which is, of course, extremely cool!).
I haven't seen a list, but here's a set of well known datasets: https://www.opendronemap.org/odm/datasets/ Some of them include the resulting imagery.
What motivated the choice of AGPL license? OpenDroneMap has dependencies on GDAL, Proj4J, GeoPackage, SciPy, Python, Nginx, and Django, among other packages. Those foundational libraries tend to have more permissive licenses (PSF, MIT, BSD 3-Clause, Apache 2.0 etc.).

I've been trying to get my organization to use ODM, but finding it difficult. The problem is analogous to the issues that Gimp has to Photoshop or Linux to Windows -- ease of use. Additionally, even if you properly configure the software the quality still is not comparable to the big proprietary players in the photogrammetry field: Bentley Systems; Pix4D; Drone Deploy. A major reason for the quality issues is that th…
By coincidence I tried this last week; it really is pretty impressive. The one thing I missed is some intros/guidance on how best to take photos to feed it; which angle, how much spacing, any tools to use in flight etc. I got pretty good results with my first run but was going to blindly experiment to see if I could improve it. Any tips?

I use the pix4d capture app for setting the flight path. It can be used to just do the capture part for free, where as their paid product can also do the stitching for you but seems prohibitively expensive for a non-professional who just wants to make a small number of maps.
I wanted to annotate a map of my property to keep track of the fruit trees I am planting. Google maps resolution for the area is extremely low, but a basic DJI drone, pix4d capture (free for capture) and ODM can give you a nice detailed imagery with very little work. The difference was being able to see a stand of trees vs individuals.

i highly highly recommend trying Colmap if you like ODM. it's not suitable for drone footage by itself (it works but why), but it has amazing performance for just handheld video walkthroughs or if you have a lot of geotagged photos. basically the next generation / natural extension of the original Bundler that brought open source unstructured SfM to the mainstream. not photo realistic or anything but very usable for…
That said, I made our drone photogrammetry pipeline with ODM and I wouldn't use colmap.
There's still some annoying things that no software can seem to do: with a single camera, I'd love to create a 3D map of a road. But no matter how much overlap of photos I get, (I mounted a stabilized GoPro to a truck and took video, than pulled together geotagged stills) for some reason I could never get a good point cloud out of that data. Even colmap. Colmap does it's absolute best if you walk around in a circle with a common central point of focus. It's frustrating because I KNOW the 3D information is there. I can see it. Plenty of features to match. But for some reason this seems to be a hard task for current SFM libraries.
