Georeferencing is the process of assigning realworld coordinates to each pixel of the raster. Many times these coordinates are obtained by doing field surveys collecting coordinates with a GPS device for few easily identifiable features in the image or map. We use three free, opensource software libraries: Quantum GIS (These instructions are based off of QGIS version Lisboa), GDAL, and TileMill.

The pixels could be from a scanned map or from a screen image.
Scanned maps can sometimes be a little distorted, but QGISs georeferencer can handle that, within User guideManual PDFs; PyQGIS cookbook; The usual procedure for georeferencing an image involves selecting multiple points on the raster, specifying their coordinates, and choosing a relevant transformation type. which appears in the QGIS menu bar.
