One other maddening quirk I forgot to mention: address always count up from the baselines, so if a road is U-shaped, with two legs heading north, and an eqast-west connector, addresses will count upward along both N-S legs *simultaneously* - xNyy0 and xNyy5 might be on one leg, xNyy4 and xNyy4 might be on the other - so you get the absurdly hilarious situation of seemingly adjacent buildings actually being a "block" apart in parallel, where that block might 1/4 or 1/2 mile. Lake County, IL uses a similar system, but with the directional letter removed. Parts of Wisconsin use *two* directionals, of the form NxxWyyy, on similar grids. -- Kristian Zoerhoff kristian.zoerh...@gmail.com _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
