Crop MLT :: tilegroxy docs

Description

This is the MLT equivalent of the cropmvt provider. A child known to produce MVT is rejected when the configuration is loaded.

Tiles entirely inside the bounds are returned unchanged. To guard against malicious tiles, a layer is also removed if decoding it would take the tile past roughly 50 MiB of memory, and any feature over roughly 10 MiB is removed from its layer.

Example

provider:
  name: cropmlt
  bounds:
    south: 51
    north: 63
    west: -7
    east: 0.1
  primary:
    name: pmtiles
    file: /data/basemap.pmtiles

{
  "provider": {
    "name": "cropmlt",
    "bounds": {
      "south": 51,
      "north": 63,
      "west": -7,
      "east": 0.1
    },
    "primary": {
      "name": "pmtiles",

    }
  }
}

Configuration options
Parameter	Description	Type	Required	Default
`primary`	The provider of the vector tile to crop	Provider	Yes	None
`bounds`	Any geometry that falls outside these geographic bounds (in WGS-84/EPSG:4326) will be removed.	Object with north, south, east, west	No	Whole world
`boundsFromAuth`	If true, use the bounds supplied via the auth context such as the geohash claim in JWT auth. If no bounds are specified via auth context then it falls back on the bounds parameter.	bool	No	No
