Hi all, As mentioned a few weeks ago, I have almost completed the development of a clean-up tool for the data to be imported. So far, it removes nonessential vertices, orthogonalizes building corners when reasonable and ensures walls' alignment within given tolerances. Building footprints that can't be processed completely are flagged accordingly, so they could be examined thoroughly at import time. Eventually, It should be easy to remove overlapping buildings (potentially generated from a 3d mapping), but I doubt that splitting terrace into individual buildings can be done automatically. The tool uses some parameters that need to be adjusted. I would like that those who are interested in this aspect of the import send me benchmark data that could be problematic. I will process them to adjust parameters and/or the tool, and I will send back the results to the sender for a thorough examination. I should soon document the process in the "Canada Building Import" wiki page (in a pre-processing section).
Thought? Comments? Daniel
