[gdal-dev] Proper algorithms for computing slopes for global/polar DEMs?

2015-02-20 Thread Jonathan Greenberg
GDALers: We're trying to figure out a good algorithm for computing topographic slope for Alaska, which is both huge and near the pole. Our DEM is currently in geographic coordinates, but we need slope over a fixed distance (change in elevation vs. horizontal meters). The issue is, there is no pr

Hi, Some time ago I opened this bug report (http://hub.qgis.org/issues/11428), because I thought it was a problem of the implementation of gdaltindex in QGIS, but now I see that it isn't, because it also happens at the command line. If I put the command line in the folder where the raster files a
