I'm working on the import of land-use data into Openstreetmap. Unfortunately I've encountered a problem that has delayed my time table.
Take a look at the picture below: the red line is the main road (it is correctly mapped using GPS devices). The white area is the region that indicated the presence of the road: it should be placed exactly above the red line. Unfortunately, this region wasn't aquired with GPS data, but it was constructed mainly with aerial imaginery (so there are projection errors and also problems with the contrast and definition of the images): this explain the matching problem with the red line.
Since I possess a limited knowledge in this particular geometric problem, I was looking for any algorithms that could help me solve this. My thought was to handle the borders of the white region as two different lines and to apply some sort of matching algorithm. Ideally, the algorithm I'm looking for should be able to compare the features of two lines, and adjust one of them accordingly to the other.
Is there something similar that could help me? Or do you have any other possible solutions?
Thank you for your help and time.
