I recently went back and looked at an area of Hillsboro, Oregon, USA that I had mapped before, and found all the street names changed in the development. In the county's GIS the names were all new (which I confirmed on a subsequent reconnaissance mission), but in Google the names were old.

After a few minutes' thinking, I realized that the development had been a trailer park (i.e. a lot for "manufactured homes"), but the trailers had been evicted several years ago and permanent housing is now being built. Although this area was still empty lots, all the street names had been changed from the old days, and Google Maps had not caught up.

I've just gotten into OSM in the last couple of weeks. Since I live in Hillsboro I've been working on streets around Hillsboro: making corrections from TIGER data and adding new construction. I've been using Potlatch, but played around a little bit with JOSM.

I've been using Washington County's GIS system for info: street names and routes, as well as eliminating private streets. I would really like to find a way to overlay arbitrary images from this or other GIS systems onto the editor. Anyone know a way to do this?

Thanks
