I was going to look at the buildings too. I’ve used a tool in ArcGIS to correct some pretty awful buildings, but I couldn’t download them either. If there is no hurry, I’d check in again with the contact on Monday. It would be nice to have the buildings with addresses on them.

I let the CT point of contact (Scott) know about the problem -- he mentioned in our communication that he forwarded the issue to the tech support team, but I haven't heard from them since then and I'm still unable to download it.

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!
