getTile

• getTile(
      z: string | number,
      x: string | number,
      y: string | number,
  ): GeoJSONVTTile

  Given z, x, and y tile coordinates, returns the corresponding tile with geometries in tile coordinates, much like MVT data is stored.

  Parameters

  • z: string | number

    tile zoom level

  • x: string | number

    tile x coordinate

  • y: string | number

    tile y coordinate

  Returns GeoJSONVTTile

  the transformed tile or null if not found

invalidateTiles

• invalidateTiles(features: GeoJSONVTInternalFeature[]): void
  Internal

  Invalidates (removes) tiles affected by the provided features

  Parameters

  • features: GeoJSONVTInternalFeature[]

  Returns void

splitTile

• splitTile(
      features: GeoJSONVTInternalFeature[],
      z: number,
      x: number,
      y: number,
      cz?: number,
      cx?: number,
      cy?: number,
  ): void
  Internal

  splits features from a parent tile to sub-tiles. z, x, and y are the coordinates of the parent tile cz, cx, and cy are the coordinates of the target tile

  If no target tile is specified, splitting stops when we reach the maximum zoom or the number of points is low as specified in the options.

  Parameters

  • features: GeoJSONVTInternalFeature[]

    features to split

  • z: number

    tile zoom level

  • x: number

    tile x coordinate

  • y: number

    tile y coordinate

  • Optionalcz: number

    target tile zoom level

  • Optionalcx: number

    target tile x coordinate

  • Optionalcy: number

    target tile y coordinate

  Returns void

updateData

• updateData(diff: GeoJSONVTSourceDiff): void

  Updates the tile index by adding and/or removing geojson features invalidates tiles that are affected by the update for regeneration on next getTile call.

  Parameters

  • diff: GeoJSONVTSourceDiff

    the source diff object

  Returns void
