Abstract:
A method for efficiently fetching map tiles for digital maps includes receiving, at a client device such as a mapping user interface device, a request to display a digital map and identifying a plurality of map tiles for the request, each map tile representing a portion of the digital map. The user interface device generates a single map content request including multiple identifiers corresponding to the plurality of map tiles. The user interface device then sends the map content request to a map content server as a single request requesting multiple map tiles. In response to the map content request, the map content server retrieves the plurality of map tiles from a content database and sends the plurality of map tiles to the client device. The client device can then display the digital map based on the plurality of map tiles.
Abstract:
A map data server may provide metadata about available indoor map data that accompanies map data for drawing a base map. For example, map data may include vector data for drawing a footprint of a building, and the metadata may include information about the physical properties of the building (e.g., an indication of how many floors the building has and if detailed map data is available for the indicated floors, etc.). A mapping application running on the client can use this metadata to display an interface that allows a user to select floors or otherwise interact with the floor data. Further, the metadata accompanying map data can include a bounding box, or a bounding polygon, for one or more floors. The mapping application can use these bounding shapes to properly reposition the viewport as map data for a new floor is being loaded, for example.
Abstract:
To identify important access roads for a geographic location, multiple previous requests for directions between a multiplicity of sources and one or more destinations identical, or proximate, to the geographic location are identified. Further, routes between the multiplicity of sources and the one or more destinations are determined. Still further, common road segments shared by at least some of the determined routes are identified, and a set of important access roads for the geographic location are selected from among the identified road segments based on how frequently the identified road segments are used.

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:
Systems and methods for applying one or more route-based modifications to a map are provided. In some aspects, a system includes a pathfinder module configured to determine a primary route from a beginning point to a destination point on the map. The pathfinder module is further configured to generate one or more primary modifications to the map based on the primary route. The system also includes a restyling module configured to apply the primary route and the one or more primary modifications to the map. The one or more primary modifications include at least one of a) adding a first object to the map that would otherwise be excluded from the map if the primary route is not applied to the map and b) excluding a second object from the map that would otherwise be added to the map if the primary route is not applied to the map.
Abstract:
A map data server may provide map data to a client device by generating a description of a geographic area that includes outdoor map features including a multi-story building. The multi-story building includes a “default” floor. The map data server may also provide data to the client device to graphically represent the indoor features of the default floor in the description of the geographic area. The indoor map features may be annotated to allow the client device to selectively activate or deactivate the display of the indoor map features.
