OSM is not whole language but a smaller tagging vocabulary for a database. In OSM schema, it turns out Viaduct was rejected as a *tag* and accepted as a *value*. http://wiki.openstreetmap.org/wiki/*Proposed*_features/*Viaduct* > *Status: > Obsoleted<http://wiki.openstreetmap.org/wiki/Category:Proposed_features_%22Obsoleted%22>( > inactive <http://wiki.openstreetmap.org/wiki/Category:Inactive_features>)* > *This proposal has been obsoleted by the approved > "Bridge<http://wiki.openstreetmap.org/wiki/Proposed_features/Bridge>" > proposal.* > http://wiki.openstreetmap.org/wiki/*Bridge* > There is a single "bridge=<type>" tag: > *bridge*=yes > *bridge*=aqueduct > *bridge*=viaduct > *bridge*=swing > *bridge*=... > so i suggest * highway=footway, bridge=viaduct,* and at least in the WDW case where we will be adding footway and service ways beneath, * layer=1 *although* *the squirrels and hedgehogs won't have layer=0 paths to conflict in the treetop case*, *there might be a ground level nature trail as well. * * (Why not tag with best word from wikipedia even if not otherwise used in OSM? While we don't tag for one render, we also don't tag to make the renderes' job impossible either; a custom tag usevid nowhere else will NEVER render unless the author provides patches to each renderer, and other database uses won't know what to make of it either.) -- Bill [email protected] [email protected]
