API

geojson(geom, limits)

Given a geometry, create cells and return them in a format easily readable by any software that reads GeoJSON.

* geom (Object): GeoJSON geometry
* limits (Object): an object with min_zoom and max_zoom properties specifying the minimum and maximum level to be tiled.

Returns Object, FeatureCollection of cells formatted as GeoJSON Features


tiles(geom, limits)

Given a geometry, create cells and return them in their raw form, as an array of cell identifiers.

* geom (Object): GeoJSON geometry
* limits (Object): an object with min_zoom and max_zoom properties specifying the minimum and maximum level to be tiled.

Returns Array.>, An array of tiles given as [x, y, z] arrays


indexes(geom, limits)

Given a geometry, create cells and return them as quadkey indexes.

* geom (Object): GeoJSON geometry
* limits (Object): an object with min_zoom and max_zoom properties specifying the minimum and maximum level to be tiled.

Returns Array., An array of tiles given as quadkeys.
