GENERATING AND SERVING TILES IN A DIGITAL MAPPING SYSTEM

摘要

Digital tile-based mapping techniques are disclosed that enable efficient online serving of aesthetically pleasing maps. In one particular embodiment, an image tile-based digital mapping system is configured for generating map tiles during an offline session, and serving selected sets of those tiles to a client when requested. Also provided are solutions for handling map labels and other such features in a tile-based mapping system, such as when a map label crosses map file boundaries. Various processing environments (e.g., servers or other computing devices) can be employed in the system.
