JOSM Elevation Plugin

Elevation is a plugin for the OpenStreetMap editor JOSM. It displays terrain elevation at the mouse pointer location on the map as well as elevation contour lines and hillshade. It is designed to use publicly available elevation data from NASA's Shuttle Radar Topography Mission (SRTM). It can be configured to automatically download SRTM elevation data as needed.
