This tool aims to (a) provide a continuous raster of Digital Elevation Raster over an area of interest and (b) perform some standard transformations for processing. Such transformations include: + converting the vertical datum from a reference geoid to the WGS84 ellipsoidal + ensuring a coordinate reference system centered at either the upper-left corner (Area tag) or center of the pixel (Point tag).

We utilize the GIS formats from rasterio. This tool was developed to support cloud SAR processing using ISCE2 and various research. The early work of this repository was done by Charlie Marshak, David Bekaert, Michael Denbina, and Marc Simard.
