From the developer:
CorrMap is a program that can calibrate and rectify any type of map available as a raster image file. It assigns real map coordinates, rectifies the orientation to the North and transforms from pixels to real measurement units. It also corrects randomly deformed maps with reference to new maps provided with a grid of control points.
