NOTE: GPS Visualizer can now add elevation data through the normal map and conversion forms, making this page mostly superfluous; click here for more information on elevation data. The only reason to use this JavaScript-based remote lookup utility would be if you have points between 60° and 90° latitude, and therefore need access to the GTOPO30 data.

GPS Visualizer's JavaScript Elevation Lookup Utility

Assign "missing" elevations to a batch of GPS coordinates

Your input must be in the form of a tab-delimited or comma-separated (CSV) table with a header row, and there must be columns defined as "latitude" and "longitude" (or "lat" and "lon"). If your data already contains some non-zero elevation values (under an "altitude" or "elevation" heading), they will be preserved.

Examples: lat,lon
- or - name,latitude,longitude,altitude
Berlin, 52.51852, 13.40463,
Madrid, 40.41676, -3.70347, 0
Paris, 48.85355, 2.34813, 35.6
Vienna, 48.20957, 16.37169,


Output separator:    Elevation units:    No lookups (why?)
