to fix the data you will need to measure the x and y error in many locations across the country. You can do this by moving the data until it aligns with known features, for example using the Elbe River in Dresden, or the Grosser Garten in Dresden. I've measured the (dx,dy) error for Dresden, Flensburg, Kassel, Düsseldorf, Stuttgart and München. http://www.geocities.com/william.gmap/adjust.htm There's a different error for each location. You will need to measure the error at many more locations, then form an interpolated surface for dx as a function of (x,y) and another surface for dy as a function of (x,y), and apply the interpolated error functions to each vertex in the original data. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
