Use of Open Source Projects

This section highlights some of the open source projects that make Wegaw products possible.

Special mention goes to the Let-It-Snow module by CESBIO. Wegaw technology works with its custom extension of this module for the processing of Sentinel-2 scenes for snow detection.
