A few questions.
How big do you foresee your constellation being?
How fair is the comparison in your Google Photos link? The image on the right seems to have significant artifacting that looks more a side effect of compression.
We used a drone to capture this image at our representative resolution (10cm), but it only captures in JPEG so there could be compression artifacts from that. The image on the right is a 1/3 downsampled version to show 30cm resolution.
Which reminds me, wouldn’t drones always be able to capture better imagery due to lower altitude? It’s my understanding Google maps is all done from aircraft on the higher resolutions.
