Serving Terrain Tiles
|
||||
--------------
|
||||
|
||||
If you serve terrain tiles, it is possible to configure an ``encoding`` with ``mapbox`` or ``terrarium`` to enable a terrain preview mode and the ``elevation`` api for the ``data`` endpoint.
|
||||
|
||||
For example::
|
||||
|
||||
"data": {
|
||||
"terrain1": {
|
||||
"mbtiles": "terrain1.mbtiles",
|
||||
"encoding": "mapbox"
|
||||
},
|
||||
"terrain2": {
|
||||
"pmtiles": "terrain2.pmtiles"
|
||||
"encoding": "terrarium"
|
||||
}
|
||||
}

Alternatively, you can use ``pmtiles://{source2}`` to reference existing data object from the config.
