Hey, I wrote GeoDeep, what a cool writeup! Glad someone tried to run these on satellite imagery. I did most of my testing on drone derived orthophotos, so was curious to see how it would perform with lower resolution images. Some models like the car model seem like they did poorly. I suspect it's probably because the ground sampling distance (GSD) was in the 35-56 cm/px range, whereas the car model was trained for 10 cm/px. GeoDeep can downscale the input to match the model's input resolution, but can't (currently) upscale it.
Very cool project! It works about as well as I would expect if you naively take a drone derived model and apply it to satellite images, but I am sure a bit of fine-tuning would improve performance.
Good job on the ease of use front: it does look really easy to use.
Thankfully this is also right in the window of much of what's being captured from aircraft in many places, too. It's not uncommon to find 7.5 - 15cm / px imagery from public agencies around the globe. Even some more philanthropic acquisitions are acquiring within this envelope.
