   function process_segment(profile, segment)
       io.write(segment.source.lat .. ',' .. segment.source.lon, '\n')
       io.write(segment.target.lat .. ',' .. segment.target.lon, '\n')
       os.exit()
   end

2. Run

   node ./scripts/build_osrm_data.js uruguay.bicycle/uruguay-latest.osm.pbf bicycle.chivia > ./data/osrm/uruguay.bicycle/latlng/uruguay-latest.txt

3. Restore process_segment function to it's original

4. Run

   node ./scripts/fetch_elevation_data.js uruguay.bicycle/uruguay-latest.osm.pbf bicycle.chivia
