Back in 2007 or so, I spent hundreds of hours aligning TIGER data to the satellite imagery in OSM, usually in cities I never had been before. If I remember correctly, I did most of Fresno. :-)
I’m totally fine with my edits being used commercially too.
- maxerickson 5y agoThe status of the initial Tiger data varies by county. Many counties were poorly aligned, but many counties were also pretty good, depending on whether the county had been updated in a quality improvement project that Census was doing when the OSM import happened.
