Adding to what Martin said, some of our reasons: 1. From the belief that individual contributions are more valuable as a whole than contributions from an automated import process. We are trying to grow a local OSM community in Austin, and I feel that throwing away the work of past contributors works against that. 2. The data we are importing was collected about 3 years ago at this point, so OSM data will be more relevant and up to date in some cases. 3. Efficiency. There are enough buildings in OSM already and as Martin pointed out, comparing them individually and properly merging tags, etc would be time consuming.
