You are grouping transmitters/transponders to a tower, and while it may not be 100% appropriate from the original intent of relations, until or unless something better comes along this is the best option that I can see to tag a single node with multiple types of the same types of information. > I think the proposal to use a node for each transponder is right.

This information isn't just useful for rendering, it can be useful to know to plan trips among other things, but before either can happen the information needs to be encoded in such a way to make this sort of thing easy to deal with and at present there isn't any easy way to do it other than using multiple relations linked to a single node. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
