I'm part of a group making global visualization software. I need to find earth imagery (visual range and hopefully IR as well) between 500 m/pixel and 75 m/pixel.
The blue marble next generation data doesn't get high enough resolution.
There seem to be some pay services for this like Planet Observer, TruEarth , and Digital Globe. I'd like to avoid paying if I could.
I see that there is Sentinel 2 data which I think might meet my needs but I'm having trouble finding how to download it. Even on the ESO website I can't find a good way to do it en masse (or at least more than one image at a time.
In the end I need the data tiled so that my project can zoom. I could probably do that myself if the data is an a reasonable form to begin with.
