[scikit-image] Techniques for Aligning images to GIS data

[Joe Kington]

You'll need to use geospatial software or libraries for this.  GDAL is your
best choice. gdal_translate with the -gcp option is what you want in this
case. You can do the equivalent from gdal's Python interface, but it's a
bit more involved. There's also a QGIS plugin to interactively build the
GDAL command, if you'd like to interactively select the coregistration
points.
