Type Alias GeoJSONVTOptions

Tile buffer on each side

Enable Supercluster for point features. Each position of a MultiPoint feature is clustered as a point of its own. Other geometry types are left out.

Options for the Supercluster point clustering algorithm. coordinates and wrap come from the options above.

The space the positions are in. 'lngLat' is longitude and latitude, which web mercator puts in the square from 0 to 1 that tile 0/0/0 covers, with latitudes beyond ~85.05 degrees clamped onto its top and bottom. 'unitSquare' is x and y in that square already, y growing downward, taken as they are, for data in another projection. getData and the cluster methods return positions in the same space.

Logging level (0, 1 or 2)

Tile extent

Whether to generate feature ids. Cannot be used with promoteId

Max number of points per tile in the tile index

Max zoom in the tile index

Whether to calculate line metrics

Max zoom to preserve detail on

Name of a feature property to be promoted to feature.id

Simplification tolerance (higher means simpler)

Whether geojson can be updated (with caveat of a stored simplified copy)

Whether the world wraps around the antimeridian. With true, features near the left or right edge are copied across it, and the tiles at either edge include what lies past it. With false, the world is the square and ends at its edges. Features are cut at the tile buffer around it, points outside it are left out of the clusters, and getTile returns null outside it. geoJSONToTile doesn't wrap unless this is true.
