资源简介:

Digital Terrain Model geomorphometry derivatives based on the DTM for Continental Europe using the EPSG:3035 projection system. Processed using SAGA GIS, GRASS 7 GIS and GDAL at 3 standard spatial resolutions: 30-m, 100-m and 250-m. Derivatives include: devmean = deviation from mean value derived using SAGA GIS, downlocal / down = downslope local and general curvature derived using SAGA GIS, hillshade = hillshading derived using using GDAL gdaldem functions, mnr = Module Melton Ruggedness Number derived using SAGA GIS, northerness/easterness = derived using GRASS 7 GIS, openp / openn = openness positive negative derived using SAGA GIS, slope = slope in percent derived using GDAL gdaldem functions, topidx = a topographic index (wetness index) derived using GRASS 7 GIS, tpi = Topographic Wetness Index derived using SAGA GIS, vbf = Multiresolution Index of Valley Bottom Flatness derived using SAGA GIS, Detailed processing steps can be found <strong>here</strong>. Read more about the processing steps <strong>here</strong>. Derivatives were chosen aiming to support soil and vegetation mapping projects. The slope.percent map at 30-m has been converted from 0-100% scale to 0-200% (Byte format) to help decrease the file size.
