Online Maps Documentation

The Online Maps web services suite offers the following APIs:

Raster
The Online Maps Raster API renders map data that is divided into gridded sections called tiles. Tiles are square images (png or jpg format) in various sizes which are available at 19 different zoom levels, ranging from 0 to 20. For zoom level 0, the entire earth is displayed on one single tile, while at zoom level 20, the world is divided into 240 tiles.
 
Vector
Similar to Online Maps Raster, the Online Maps Vector serves data on different zoom level ranging from 0 to 22. For zoom level 0, the entire earth is displayed on one single tile, while at zoom level 22, the world is divided into 244 tiles.
The Online Maps Vector Service delivers geographic map data packaged in a vector representation of squared sections called vector tiles. Each tile includes pre-defined collections of map features (points, lines, road shapes, water polygons, building footprints, ect.) delivered in one of the specified vector formats. Format of the tile is formally described using protobuf schema.
