how to merge rasters with different projections with correct transforn? For example EPSG:32636 and EPSG:32637

if i do it with gdal_retile command, i have correct view for EPSG:32637 rasters and uncorrect for EPSG:32636

    Welcome to GIS.SE. Can you please extend your question (just click edit below the question) with a bit more context, such as what format the rasters are, how you intend to combine them (join, overlap, merge), and what you've already tried (e.g. exact command line). – BradHards Jan 14 '14 at 6:58

you can use gdalwarp to reproject one of your raster into the projection of your second raster.

EDIT : as mentioned by BradHart, this may cause severe distortions if you have a large E-W swath. In this case you should project both raster to a third projection (e.g. EPSG 3857 at low latitude, conic at mid latitude or azimuthal near the pole). See here for more details.

  • projecting information outside its UTM zone may produce strange results. In this case they are adjacent, but another projection may be better. – BradHards Jan 14 '14 at 7:40
