1. A computer-implemented method for pre-fetching data from a remote mapping system to client computing devices for use by mapping applications, the method comprising:
determining, by one or more processors, a map location for which a user of a client computing device is likely to request data via a mapping application, prior to receiving an explicit request corresponding to the one map location from the user;
obtaining, by one or more processors:
(i) map data in a vector format for rendering an interactive digital map of the map location, at a first zoom level, and
(ii) place page data for a larger geographic area than covered by the map data, the place page data corresponding to one or more places at the map location, wherein the place page data includes one or more of text, graphics, and data feed data describing the corresponding place, wherein at least some of the place page data corresponds to a zoom level other than the certain zoom level of the map data; and wherein the map data and the place page data correspond to a same geographic region,
in response to receiving a request from the client computing device, specifying the first zoom level, sending the map data and the matched place page data from the remote mapping system to the client computing device, including sending the map data separately from the place page data, so that the place page data is available independent of all or some of the memory burden of the corresponding map data;
storing the map data and the matched place page data in a cache memory of the client computing device; and
subsequently retrieving the map data and the matched place page data from the cache memory of the client computing device without further communication between the remote mapping system and the client computing device.
