Hi, I've been rereading the wiki entry. Is it proposing a structure in which each transponder is first created as a node labeled "man_made=communications_transponder" each with all their details. Than they are grouped as a relation with the "type=communication_tower_group". Presumably the group could also have height for the mast and other information? regards Gary _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
