Gigafactory 3 Video and Satellite Pictures
The satellite pictures from Sentinal 2 show some new roads and a white pad. The white pad could be cement.
Sentinel-2 is an Earth observation mission from the EU Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 meter to 60 meter) over land and coastal waters. The mission is a constellation with two twin satellites (Sentinel-2A and Sentinel-2B).
There is weekly to daily tracking of all SpaceX sites with drones, satellite and public videos. Satellites and drones can provide this monthly monitoring for almost location on earth.
Planet Labs has 150 satellites in orbit including their Dove, SkySat, and RapidEye constellations and are collecting over 300 million sq km of imagery daily. Planet Labs has global, daily 3-5 meter per pixel resolution imagery and global, high temporal cadence sub-1 meter pixel resolution imagery.
There was drone video taken by Vincent.
