TL;DR: Cadastre in the US is untidy. (1) Boundaries through buildings are not at all uncommon. Typically, the landowner owes some apportionment of property tax to both jurisdictions. The people I know who live in property that lies in multiple school districts have the choice of which public

Some of the US boundary data gives "USGS DRG" as a source. This seems to stand for "Digital Raster Graphic" files. It is my suspicion that this raster was vectorized as part of an import process, but I have no documentation to support that. Still, I consider it a convenient explanation for why the

Both of those are different from the boundaries in TX GIS systems (mainly TxDOT). The T-17 is closer than the ancient Tiger, but still slightly different. http://gis-txdot.opendata.arcgis.com/datasets/09cd5b6811c54857bd3856b5549e34f0_0?geometry=-97.702%2C32.666%2C-97.619%2C32.721&mapSize=map-maxi

Yikes! In that case, I typically open the relation for the boundary, delete the old geometry from the relation, save, check if I can remove any unneeded ways, add the new data as tag-less ways, and then reconfigure the inner/outer roles. This has the benefit of preserving the boundary relation whil

Frederik, These boundaries are often very outdated. I don't know which TIGER vintage they were imported from. I have been replacing them piecemeal from current TIGER as I work, but we should probably replace them altogether and have a plan to keep them updated. I don't think they interfere with

Hi, I've recently traced a little bit of stuff in Annetta, TX. The area I looked at had a lot of potential for someone interested in mapping from aerial imagery (houses, tracks, driveways, parking missing; some driveways tagged as highway=residential etc.) and I did what I could in the small area
