Hello, I try to make simple (in theory) shaded relief based on SRTM data and blend it with Landsat7 RGB composite. I have converted SRTM WRS2 (p187r025) tile from LatLong to UTM z34 to match my Landsat data. The thing is that the landsat image is somewhat rotated/skewed, which I guess is specific to ETM imagery rather than to UTM projection. When I try to combine rasters using r.blend I get an misaligned image.
Here is the shaded relief I want to use: http://alrc.justdied.com/gis/srtm_shaded_small.png and r.info: http://alrc.justdied.com/gis/srtm_r.info_.png Landsat raster: http://alrc.justdied.com/gis/lsat_rgb_not_good_small.png and info: http://alrc.justdied.com/gis/lsat_rgb_r.info_1.png r.blend result (d.rgb used to display color channels): http://alrc.justdied.com/gis/blend_wrong_small.png What can I do to make terrain on landsat image actually face north as is on the srtm relief? I spend much too many hours on this issue, any help will be appreciated.
