I have problem to reproject a raster file in BNG British National Grid to WGS84.
gdalwarp -s_srs EPSG:27700 -tps -t_srs EPSG:4326 -co TFW=YES -r near input.tif geo_output.tif
I have some questions:
Must be the input file a GeoTiff file?
Which requirements must be met by the input file?
If the input file is a GeoTiff, do I need ground controlpoints?
Thanks for help.
