Satellite datasets

Imagery: The Copernicus Sentinel-2 provides free access to satellite data. "The revisit frequency of each single SENTINEL-2 satellite is 10 days and the combined constellation revisit is 5 days," according to the website. The satellite carries an "optical payload with visible, near infrared and shortwave infrared sensors comprising 13 spectral bands: 4 bands at 10 m, 6 bands at 20 m and 3 bands at 60 m spatial resolution (the latter is dedicated to atmospheric corrections and cloud screening), with a swath width of 290 km."
Elevation Data: USGS Earth Explorer
