Abstract
Methods, systems and apparatus are described to render a map according to hybrid map data. A map may be generated by a map service and sent to a client device. Hybrid map data composed of raster graphics data and vector graphics data may be generated by a map service to be sent to and rendered on a client device. A client device obtains hybrid map data, renders the vector graphics data using vector graphics, renders the raster graphics data using raster graphics, and displays the map view. A client device may receive input modifying the zoom level of the displayed map. In response a client device may render the vector graphics data at the modified zoom level and scale the raster graphics data to the zoom level. Some embodiments may obtain update raster graphics data.
