Despite the author's criticisms, it seems like there's lots of opportunity for UAV-generated open source imagery, but I can't really find an active community for sharing it.
Open Aerial Mapp[1] seems like a good start, but doesn't seem to be particularly active.
Seems like we could use a "Mapillary[2] but from Above" type of project - only one that doesn't end up getting acquired by Facebook.

- arthur2e5 3y agoODM is a way to preprocess data before sending it to OAM, but it does not itself provide a sharing platform. One barrier for OAM seems to be that it requires the image to be already orthorectified. To be more like Mapillary you'd need a service that takes georefed pictures and does its own processing. In the case of airplane window photos where georef is not going to be good enough, you might need existing photos to correlate with -- ADS-B track combined with time can help provide a starting guess, but not much else.
- fxtentacle 3y agoI tried to run the numbers on a similar idea some years back and our conclusion was that the processing power needed to do the photogrammetry ends up being more expensive than just renting long-term read access to the downlink from a high-resolution satellite.
