points2gcp
Convert ground control points for georeferencing raster files from an exported QGIS points file to the format required for the GDAL command line interface (for use with the -gcp flags).
At the moment, the pointsfile is simply hard-coded into the pythion script, though this could easily be made to be an argument if needed. For example, the provided points file is therefore converted as shown below:
$ python points2gcp.py Which outputs:
