Cloud removal from Satellite Imagery in GeoTrellis

by Anuj Pahuja for The Eclipse Foundation

Clouds and cloud shadows often obscure parts of images acquired by satellites or other sensors. However, useful image data could be extracted from other non-cloudy images of the same geographical location that can be used to fill these obscure parts. When combined together with the right algorithms, these images can offer a cloud-free view of that area. Adding this functionality to GeoTrellis would enable users to run this process over any amount of imagery, in a scalable way.
