Local data import opportunities


Much of the existing data comes from the TIGER and GNIS imports. Both datasets suffer from being significantly out-of-alignment from reality. If you see an object that doesn't match up with where it should be, feel free to adjust it into line or redraw it in a more accurate location. The Yahoo imagery and GPS tracks tend to be accurate. TIGER data in the outer metropolitan areas is better aligned than that in the inner city.

Cleaning Up Area

I few notes on some large scale changes I have been doing:

  1. I have reclassified many of the Salt Lake City roads so they make sense. See: User:Kevina/Salt Lake City Highway Classification. Many areas can still use some work. Please help but first read: United States Road Classification Guidelines
  2. I ran a script to clean up the street names. See: User:Kevina/Salt Lake Grid Cleanup Script. There is still more work to do here.
