Re: [gdal-dev] decimal rounding issue when re-projecting

Hi, Thanks a lot for the quick answer. Indeed, adding the -tr 20 20 solved the problem. As you pointed out, it should be possible to do the transformation in one step, however I want to keep an intermediate .tif file for visualization. The 20/21m per pixel resolution I had at first, even if

[gdal-dev] decimal rounding issue when re-projecting

Hi, I'm re-projecting (from stereographic to gnomonic) the PDS LOLA 20m/pix DTMS from the lunar south pole. Im using gdalwarp like this: 'gdalwarp -t_srs '+proj=gnom +lat_0=-90 +lat_ts=-90 +lon_0=0 +k=1 +x_0=0 +y_0=0 +a=1737400 +b=1737400 +units=m +no_defs' topo_stereo.tif topo_gnom.tif' .
