Elevation - SRTM3

Shuttle Radar Topography Mission (SRTM) elevation data. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000. The dataset covers land areas between 60 degrees north and 56 degrees south. This web service is using SRTM3 data with data points located every 3-arc-second (approximately 90 meters) on a latitude/longitude grid.

Parameters : lat,lng; sample area: ca 90m x 90m Result : a single number giving the elevation in meters according to srtm3, ocean areas have been masked as “no data” and have been assigned a value of -32768.

Example:

api.srtm3(lat: 50.01, lng: 10.2)

# File 'lib/geonames.rb', line 359
