Geo Elevation

An exploration of adding elevation (altitude) information to geo data.

The Problem

Publishers of elevation information on the web could make additional use of this information (e.g. in Google Earth) with a standard format.

Aviation data in waypoints is particularly used in aviation.

Participants

• Alexander Graf, DERI Innsbruck
