Abstract: The memory of a user device stores map data for rendering a digital map of a geographic area. The memory also stores searchable geospatial data organized into tiles. Each tile corresponds to a respective portion of the geographic area of a substantially same size. The geospatial data includes, for each of the tiles, descriptions of one or more geographic entities and a location of the one or more geographic entities, within the corresponding portion of the geographic area. The processing hardware of the user device is configured to (i) display the digital map via the user interface, (ii) receive the map data and the searchable geospatial data from the map data server, in the online mode, (iii) receive a geographic query pertaining to the geographic area, and (iv) execute the geographic query using the geospatial data stored in the computer-readable memory.

Abstract translation: 用户设备的存储器存储用于渲染地理区域的数字地图的地图数据。 记忆体还将可搜索的地理空间数据存储到瓦片中。 每个瓦片对应于基本相同尺寸的地理区域的相应部分。 对于每个瓦片，地理空间数据在地理区域的相应部分内包括一个或多个地理实体的描述和一个或多个地理实体的位置。 用户设备的处理硬件被配置为（i）经由用户界面显示数字地图，（ii）以在线模式从地图数据服务器接收地图数据和可搜索的地理空间数据，（iii）接收 涉及地理区域的地理查询，以及（iv）使用存储在计算机可读存储器中的地理空间数据执行地理查询。
