Gapless-REMA100: A gapless 100-m Reference Elevation Model of Antarctica with voids filled by multi-source DEMs
Here we generate a gapless 100-m reference elevation model of Antarctica (Gapless-REMA100) with the voids filled by combining multi-source DEMs. All the voids in original REMA mosaic were automatically filled from multi-source DEMs e.g., TanDEM-X PolarDEM and other freely available DEM products cove...
