Abstract:
1. A computer-implemented method for updating map tiles, the method comprising: receiving, by one or more computing devices, an update to a feature in geospatial information that describes a map, wherein the map is represented by multiple tiles rendered from the geospatial information, and wherein the update to a feature in geospatial information that describes a map is represented by a temporary display object overlayed on the multiple tiles representing the map; rerendering, by the one or more computing devices, at least one tile from the tiles based on the update to generate an individual rerendered instance of the tile; storing, by the one or more computing devices, a tile version identifier and an association between the tile version identifier and the individual rerendered instance of the tile, wherein the tile version identifier uniquely identifies the individual rerendered instance of the tile; and providing, by the one or more computing devices, the tile version identifier, instructions for using the tile version identifier to send a request for the individual rerendered instance of the tile, instructions for replacing an existing instance of the tile with the individual rerendered instance of the tile, and instructions for ceasing overlaying of the temporary display object on the map in response to receiving the individual rerendered instance of the tile, wherein the temporary display object represents the update to the tile.
