Character scalar containing openrouteservice API key
Output format. By default the response is being parsed to a list-based R object
3D point or line geometry structured according to output:
for "text", a character vector of length 1 re-encoded to UTF-8.
for "parsed", a parsed R object.
for "sf", a simple features sf object.
A GeoJSON based service to query SRTM elevation for Point or LineString 2D geometries and return 3D geometries in various formats.
