It is really hard, to setup in particular a long route relation. You need excellent knowledges of all places in detail. Because this is not possible i.e for an e-road with about 5000 km length, people set up projects in the wiki in order to establish this relation within month' and years as teamwork. The same applies i.e. to the public transport net, which is collected in many towns nearly complete, the relations of motorways, national- and other referenced roads, the borders of towns and suburbs, by relation splitted lanes of multilane roads with left-turn, right-turn-function etc etc. One of the most important advantages of the cycle- and hiking-map are the routes, which are long in many cases as well. With destroyed routes these maps lose much of their sense of exist. And all these routes can be destroyed within seconds by "harmless editings" and shoot down this long lasting work within seconds. Cause it is really hard, i.e. to insert a short OSM-way (misleaded by the editor-software) at the correct position of the relation, if you do not have excellent knowledge 1) of the object and 2) of every place in detail. Try it and you know, what I mean. That means, you have to wait for a person that has both and finds this dispersed way. And that could last very long. If the one, who established the route possibly in a rurely area, does not come back, the chances are good lasting years. If one founds this mistake in his home-area, he has no chance to heal it, if he has no clue i.e. from this bycycle-route or the public-transport. In the case of navigation systems, their users could be misguided because of such "harmless editings". I.e. in case of a destroyed left-turn-lane-relation you have to "Go straight ahead!" Thus I am the opinion, I should have to hnow "this". _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
