Abstract
To provide map data to a client device for rendering a raster map image including map elements corresponding to various physical entities, map data is generated in a non-raster format. A method includes generating a description of a map feature that includes two or more of the map elements and does not include at least one of the map elements, where the map elements included in the map feature correspond to related physical entities or portions of a same physical entity. Generating a description of the map feature includes providing an indication of a portion of the map data corresponding to the map feature providing a map feature identifier that uniquely identifies the map feature. The method further includes causing the map data and the description of the map feature to be transmitted to the client device via a communication network.
