I'm following the outline here, to load a DEM: http://sourceforge.net/apps/mediawiki/qlandkartegt/index.php?title=Use_SRTM_data_as_Digital_Elevation_Model_(DEM)
I'm using the OpenCycleMap, the 1st time thru I got an error when I loaded the DEM, so I modified the gdalwarp cmd to use the correct parameters: gdalwarp -t_srs "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs" -r cubic $file $file.tif; Then after stitching the files together and optimizing as shown here, http://sourceforge.net/apps/mediawiki/qlandkartegt/index.php?title=Use_SRTM_data_as_Digital_Elevation_Model_(DEM) I still get an error when trying to load the DEM: "DEM projection does not match the projection of the basemap. Map: +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs DEM: +proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=6378137 +b=6378137 +units=m +no_defs" Sure enuf this matches the output from gdalrsinfo localhost:gdalsrsinfo j12.tif PROJ.4 : '+proj=merc +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=6378137 +b=6378137 +units=m +no_defs ' Some of the parameters (lat_ts=0, +nadgrids=@null) are not being applied I'm new at this and don't know what I'm doing :) Can someone tell me what's wrong? Is possible that I could just ignore the error message? ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
