Abstract: Multiple individually renderable map elements, each representing a respective physical entity in a geographic area, are rendered to generate a digital map of the geographic area. A description of an aggregate map feature that includes several but not all of the multiple map elements is received. The several map elements represent physical entities that form a common administrative unit. A selection of one of the several map elements is received via the user interface. In response to receiving the selection, the several map elements included in the aggregate map feature are automatically selected, and an indication that the aggregate map feature has been selected is provided on the user interface.

Abstract: A map server generates a set of base map tiles having vector descriptors, each indicating a geometry of a respective map element, in accordance with a non-raster format for rendering a first map image. The map server provides the base map tiles to the client device. Upon receiving an indication that a specific map image for the selected geographic region is to be rendered at the client device, the map server generates a set of difference map tiles that indicate changes to be made to the set of base map tiles and sends the difference map tiles to the client device for use, along with the set of base map tiles, in rendering the requested specific map image. The client device renders the new map view defined by the difference map tiles without needing to again pre-process all of the features or elements defined in the base map tiles.

Abstract: To provide map data for rendering map images corresponding to a selected geographic region at a client device, a map server generates a set of base map tiles having vector descriptors, each of which indicates a geometry of a respective map element, in accordance with a non-raster format for rendering a first map image. The map server, at some point, provides the base map tiles to the client device. Upon receiving an indication that a specific map image for the selected geographic region is to be rendered at the client device, the map server further generates a set of difference map tiles that indicate changes to be made to the set of base map tiles and sends the difference map tiles to the client device for use, along with the set of base map tiles, in rendering the requested specific map image.

Abstract: A mapping system allows a user to interact with any location on a digital map and present the user with location related information associated with the selected location. The location related information may be in the form or a card, pop-up, image, or other graphic and may be displayed on the map at or near the selected location, around the map, etc. The displayed location related information may include predetermined or pre-stored data about the location or may include location related information collected and generated on the fly in response to the user interaction with the digital map. The displayed location related information may be displayed in the same graphical format on the digital map regardless of whether location related information is predetermined information about the location that already exists or information that is collected and generated on the fly in response to the user interaction.

Abstract: A viewing window of a map surface is determined, at a certain zoom level corresponding to the magnification of the map surface. A first set of style parameters for applying to a feature of the map surface, where the feature is described in a vector format using several interconnected vertices, is determined. The first set of style parameters corresponds to a first zoom level of the viewing window, and the first zoom level corresponds to a first magnification. A second set of style parameters for the feature is also determined, where the second set of style parameters corresponds to a second zoom level of the viewing window, and where the second zoom level corresponds to a second magnification. A third set of style parameters for displaying the feature is determined by interpolating between the first set of style parameters and the second set of style parameters.

Abstract: A graphics or image rendering system, such as a map image rendering system, may receive map data associated with a set of zoom levels, where the map data includes style attribute data corresponding to various features of a map surface at corresponding zoom levels. The system may interpolate at least some of the style parameter values from the received map data to provide style parameter values over a range of zoom levels.
