Would be nice to have a place to share the most important relations in the world... asked 25 Sep '10, 21:59 Kozuch |
It might be important to note that "category" relations are discouraged in osm - if something can be derived from the data itself, it is usually suggested not to create a relation of it (like "all rivers in a country" or "top 10 longest rivers"), so either this data would be retrieved from osm api (once implemented), or kept separately. As noted, separate lists have the problem of reference ID becoming stale over time. answered 27 Sep '10, 12:19 Richlv Okay, that makes sence. However, I was replied with "API" several times already, but I can not really handle those andwers. I need a simple service that plots the tag searches right into the map.

People do keep such lists of relations on the Wiki sometimes, but this is difficult since there is no guarantee whatsoever that relation IDs are constant. Thus, you cannot really link to them by ID - someone might at any time delete and re-create the relation, or split it in half, or do something else with it. answered 25 Sep '10, 23:07 Frederik Ramm ♦ Jochen Topf Why should the IDs change?

Because any OSM element can be deleted and recreated with a new ID at any time.

Additionally, a node or way could be moved elsewhere and have all its tags changed while keeping the same ID.

There is a list of osm relations. It is includet in the planet.osm file. All you need to do is extract the relations from the XML and sort them by your personal importance order. answered 07 Jan '11, 15:36 Kartograefin |
