Vector tiles for web or mobile maps
We offer the map POI's service in the Mapbox vector tiles format.
Currently two dynamic layers are supported:
pois - all API objects. Each object contains a Point type geometry and a unique object identifier (id). Most objects also contain a name field. You can use the id as a parameter of the /{lang}/places/xid/{id} function to get information about an object.
heat - groups of points corresponding to API objects intended for creating heatmaps. Each layer object contains a Point type geometry and the number of points n that are included in the object geometry. The heat layer object with n=1 corresponds to one object from the pois layer.
