Hi, Does the altitude attribute represents a relative altitude? If I have a tunnel below a railroad, should I set altitude to -1? Thanks! |

The tunnel under the railroad should probably be marked as layer=-1. Sometimes it will be a different value for the layer, but the usual tunnel will be Altitude is usually stored in the ele key (short for elevation). It should probably only be used on a limited set of objects where the elevation is well determined (things like mountain peaks). In general combining OSM data with separate elevation data is a better approach than adding elevations of various accuracies and sources to objects. Thanks, Vincent and Max!

What altitude attribute are you talking about exactly? Can you give us the name of the tag key?
The name in spanish is "altitud"
