I am trying to georeference a tif image with the QGIS GUI, and then I load and save the Gdal script. With the QGIS GUI, I managed to get a decent picture, then I exports it in Geotif.
I would like to use the gdal executable store in the qgis file (bin file) for the same operation. So, I try to do the same operation with a DOS command with gdal_translate and gdalwarp. But it doesn't work. The operation with the DOS command gives me a black image. With the same gdal script, under QGIS, the image is correct. I only make a copy paste under the DOS command. The first part, the gdal_translate seems to work, and I think it is the gdalwarp the problem.
These are my command lines :
gdal_translate -of GTiff -gcp 18.4111 34.3009 *(... a lot of GCP ...)* "S:/image/geotiff/TrueMarble.tif" "C:/Users/userme/AppData/Local/Temp/TrueMarble.tif" gdalwarp -r cubicspline -order 3 -co COMPRESS=NONE -dstalpha "C:/Users/userme/AppData/Local/Temp/TrueMarble.tif" "S:/image/geotiff/Poly3"
