Sometimes they are not very accurate geocoded or sometimes out of date, especialy in different zoom levels (eg http://de.maps.yahoo.com/#mvt=s&lat=39.153668&lon=-94.537782&zoom=18 vs. http://de.maps.yahoo.com/#mvt=s&lat=39.153668&lon=-94.537782&zoom=17 ). Of course, if you don't have a better source (like GPS-Traces) Yahoo is better than nothing. > But before I do to much damage it would be nice if someone could give > me "constructive criticism" if and what I am missing and if I am > doing things correctly. see this area > http://www.openstreetmap.org/?lat=37.6777&lon=-97.3922&zoom=14&layers=B000FTF Just with a quick look: You forgot a few bridges at the intersection of HW 54 and I 235 (the railwaybridge and the bridge over the river of HW 54). Also take care of the layer tag (http://wiki.openstreetmap.org/wiki/Layer) to describe which way is above / underneath. Also the begin and end of the current bridges doesn't match the Yahoo images. I normaly compare with Google street view and the bird's eye view from http://www.bing.com/maps/ if unsure where objects start or end. > and > http://www.openstreetmap.org/?lat=38.0556&lon=-97.3127&zoom=14&layers=B000FTF Notice that railway nodes are not connected to highways nodes even if it looks like they have a common node. > we have dirt and/or sand or gravel roads every mile - I think I'll > put surface=unpaved and surface=dirt, is there a preferred way to > designate , like the UPS and Fedex men have maps, of which roads are > not passable when wet? Giving an information about the surface is not a bad idear. Esp. if you live in an area where you can't assume that a residential highway will always be paved and have boardwalks on every side. Unfortunately we don't have a tag describing the way atdifferent weather conditions. People living in areas where dry riverbeads are used as roads except in rainy season when it should be tagged as a river... :) > so help me make sure I understand these levels ... Have a look at http://wiki.openstreetmap.org/wiki/United_States_roads_tagging There is a discussion at the moment (or better since openstreetmap comes more popular) if we should tag highways according to their official classification or their physical charakteristics. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
