So, it's been a week since that last message. Do you think we should import addresses and buildings at the same time? Should we import the buildings first and care about addresses later?
Yury, what are your thoughts about the data source quality? Do you think it's a good idea to import from WestCOG and maybe rely on CT data for the rest of CT? I tried playing with the data and I didn't see any difference between drawing the buildings from scratch and having to simplify and correct CT's data. Thanks!
