Altitude explorer

Altitude Explorer
Explore the terrain beneath your routes with precise elevation data powered by the Copernicus DEM GLO-90 — a global Digital Elevation Model derived from TanDEM-X radar imagery, operated by DLR and Airbus Defence and Space under the European Union's Copernicus Programme.
Global coverage of all land areas (approximately 90S to 84N latitude, 180W to 180E longitude).
What you can do
• Point query — tap anywhere on the map to get the exact elevation at that location
• Line profile — place two markers and instantly generate a cross-section of the terrain between them
• Road profile — follow a real driving or walking route and see how elevation changes along the way
• Track import — load GPX, KML, KMZ, or GeoJSON files and visualise the elevation of your own tracks
• Interactive chart — drag a scrubber along the profile chart to read elevation and distance at any point
• Saved profiles — store your profiles in a personal library and revisit them anytime
• PDF export — export any profile as a PDF with map snapshot, chart, stats and full data table
Data & accuracy
The dataset is hosted on proprietary servers for fast, direct access across all supported regions. Accuracy varies with terrain complexity — dense vegetation, steep slopes, and urban areas may introduce artefacts. Full attribution and the Copernicus Data Policy are available directly within the app under Settings → About.
Customisation
Choose your units (km/miles, m/ft), map style, interpolation algorithm, chart colour and line weight. Available in English, Italian, French, German and Spanish.
