<pre>Hello,<br>i tried to reproject a set of raster data from originally Gauss-Krueger<br>EPSG:31467 to latlong EPSG:4326 using gdalwarp.<br><br>gdalwarp -co TILED=YES -co BLOCKXSIZE=512 -co BLOCKYSIZE=512 -co<br>COMPRESS=LZW -s_srs '+proj=tmerc +lat_0=0 +lon_0=9 +k=
1.000000<br>+x_0=3500000 +y_0=0 +ellps=bessel +datum=potsdam +units=m +no_defs '<br>-t_srs '+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs '<br>z2_45_18_l0.tif z2_45_18_l0_wgs84.tif<br><br>i also tried <br><br>
gdalwarp -co TILED=YES -co BLOCKXSIZE=512 -co BLOCKYSIZE=512 -co<br>COMPRESS=LZW -s_srs EPSG:31467 -t_srs EPSG:4326 z2_45_18_l0.tif<br>z2_45_18_l0_wgs84.tif<br><br>But doing so i get the following error.<br><br>Copying color table from z2_45_18_l0.tif to new file.
<br>ERROR 1: geocentric transformation missing z or ellps<br>ERROR 1: GDALSuggestedWarpOutput() failed because the passed<br>transformer failed.<br><br>Does anyone have an idea how to solve this problem.<br><br>Kind regards
