Since V29879 the plugin is able to read elevation data from external SRTM files Observed images, research and application examples using ALOS (Prism, Avnir-2 and Palsar) and ALOS-2 (Palsar-2). Srtmfill reads and writes the .hgt file format that SRTM DEMs are currently supplied in. Any software currently able to read these HGT files (such as World Construction Set, Visual Nature Studio or any GIS software) should be able to read… In our case, we will download the file that covers the region from latitude 37-38 degrees North and longitude 122-123 degrees West. 1 Vysoké Učení Technické V BRNĚ BRNO University OF Technology Fakulta Informačních Technologií Ústav Intelig
