as far as I understand from your original post you want to add a raster
layer to QGIS whose projection information is +proj=lcc +lat_1=49.5
+lat_0=49.5 +lon_0=0 +k_0=0.99987734
+x_0=600000 +y_0=200000 +a=6378249.2 +b=6356514.999978254
+nadgrids=ntf_r93.gsb,null +pm=2.337229167 +units=m +no_defs +to
+proj=lcc +lat_1=44 +lat_2=49 +lat_0=46.5 +lon_0=3 +x_0=700000
+y_0=6600000 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs
so you have to edit this information in the file (gdal_edit or gdal_warp
will probably do) adding the path to the gsb file. Alternativly it
_might_ work to copy the gsb file at the same location as the raster
file (never tried, though).
