Sentinel-2

Sentinel-2's Multi-spectral Instrument (MSI) is a wide-swath, high-resolution, sensor supporting Copernicus Land Monitoring studies. It is used for the the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.

The visible and near-infrared bands on the MSI are available at 10 meter resolution, while the short-wave infrared bands are at 20 meters. There are two Sentinel-2 satellites (Sentinel-2A and Sentinel-2B), both with an MSI and orbiting in sync providing a scene every 5 days, with near-global coverage. Sentinel-2A was launched in mid 2013, and Sentinel-2B in mid 2016, so it does not have as long of a historical archive as is available with the Landsat data.

The Sentinel data was used for mapping large commercial farms. By using a false color image that enhances vegetation (Blue, Shortwave-IR and Near-IR), it was easier to see the large farms. The scenes were used to create a single mosaic, clipped to the boundaries of the Ethiopia lowlands and imported into the JOSM OpenStreetMap editor to map the farms.
