Abstract: First map data is generated in a vector format for displaying a first map image at a client device. The first map image corresponds to a perspective of a camera panned to a certain location at a certain zoom level. The first map data is provided to the client device via a communication network. Modification data is generated at a map server in a vector format, the modification data specifying a difference between the first map data and a second map data, where the second map data is for displaying a second map image corresponding to the same perspective of the camera panned to the same location at the same zoom level. The modification data is provided to the client device via the communication network for generating the second map image using the first map data and the modification data.

Abstract: To generate a description of a raster map image that includes a representation of a body of water having a color gradient that appears constant in response to a zoom operation, a description of geometry of the body of water is generated for a selected geographic area. Using a raster representation of the body of water having a color gradient, at least two blur raster images are generated: a first blur raster image is generated using a first blur radius, and a second blur raster image is generated using a second blur radius different from the first blur radius. The description of the geometry of the body of water, the first blur raster image, and the second blur raster image are provided to a client device for generating raster map images of the selected geographic area.

Abstract: A computing device receives, via a communication network, map data including (i) a description of geometries of map features and (ii) a first description of visual characteristics defined separately and independently of the description of the geometries. The computing device applies the visual characteristics to the geometries to render a first digital map. The computing device then receives, via the communication network, a second description of visual characteristics for application to the geometries previously provided to the computing device as part of the map data, and applies the second visual characteristics to the previously received geometries of the plurality of map features to render a second digital map.

Abstract: To organize configuration parameters for rendering map features on digital maps, a data structure storing multiple nodes is generated. Respective sets of map feature attributes and configuration parameters are assigned to the nodes. The configuration parameters specify visual attributes for rendering map features. Indications of relationships between the nodes are generated, where at least several of the nodes include several child nodes. An indication of one or more map feature attributes to which a certain map feature belongs is received, and the data structure is traversed according to the indicated relationships between the nodes to generate a set of configuration parameters for rendering the map feature. Traversing the data structure includes comparing the indicated map feature attribute or map feature attributes to sets of map feature attributes at some of the nodes, such that the generated set of configuration parameters includes configuration parameters from at least two of the nodes.
