I have a tiff image and I would like to georeference it, and so create a Geotiff. To do that, I have to use GDAL. I use in particular, the executable store in the QGIS file (gdalwarp.exe, gdaltranslate.exe...).
For now, I use this code in a DOS command (command line), and this doesn't seem to work.
gdal_translate -of GTiff -gcp 33.9983 669.668 -833589 -692.339 -gcp 124.661 1377.97 -833520 -1379.2 -gcp 6788.34 -10.2993 -826876 6.06375 -gcp 6839.33 748.997 -826813 -755.83 -gcp 3014.52 363.682 -830651 -363.339 -gcp 3892.81 1032.32 -829762 -1021.34 "D:/Users/(...)/Desktop/image_projetee_UTM.tiff" "C:/Users/(...)/AppData/Local/Temp/image_projetee_UTM.tiff"gdalwarp -r near -order 1 -co COMPRESS=NONE -dstalpha "C:/Users/(...)/AppData/Local/Temp/image_projetee_UTM.tiff" "D:/Users/(...)/Desktop/image_projetee_UTM_georef.tif"1 - After run this code, the output image is not a GTiff but a Tiff like the input image.
2 - If I try to open the output image in Google Earth for example, it doesn't seems at all georeferenced
I think I missed something in the way to georeferenced a Tiff file...
Can anyone help me ?
