A registration process is necessary because image edges and cadastre edges do not correspond, since farmers need not strictly follow fiscal divisions. The problem of registering a cadastre graph onto an image is formalized as a graph matching problem, which is solved by simulated annealing. Additionally, a score for each cadastre edge is obtained, which shows which edges can be found in the image and which cannot. Minor geometrical deformations and acquisition errors can also be corrected.

The system has been tested on 2.5m per pixel and 1m per pixel aerial images processed to have the characteristics of SPOT 5 and Ikonos output. A system using simple geometric models gives good results for bridges over roads and railroads, and very bad results for bridges over larger regions such as rivers. In contrast, a system using a texture-based classification and hand-made rules applied to that classification gives good results for bridges over rivers and railroads, and bad results for bridges over roads.
