Elevation API

Elevation proxies to ELEVATION_URL, which Docker Compose points at the local SRTM HGT service.

Routes

GET /elevation/v1/{lon,lat}
GET /elevation/v1/{lon,lat;lon,lat}
GET /elevation/v1/along/{lon,lat;lon,lat}?samples=100

Point lookups accept up to 100 points. Along-route profiles require at least two points and sample up to 500 interpolated locations.

Requests require API key or session auth.
