Umbra Synthetic Aperture Radar Public Data
The Umbra satellite produces SAR images of the highest resolution (better than 25 cm/10 inches) ever commercially available. Synthetic aperture radar satellites can capture images at night, through clouds, smoke and rain. SAR is unique in its ability to detect changes. The Open Data Project (ODP) monitors ten different locations around the world. Frequently updated with new images. ODP enables users to analyze time series data to detect changes at each location.

Data Subset¶
Since GEC data are already encoded as geotiffs, only GEC data were selected from existing datasets. The SAR GEC data is a geocoded product that is tiled to a single altitude to reduce visual artifacts. It is analyzable, although it also involves pauses and advances. SAR GEC data is usually obtained as a product of radar image processing from slope or ground ranging. It only contains amplitude information.
