Abstract
A computer-implemented method and system for pre-fetching remote resource data from a remote mapping system for display on a client computing device is disclosed. Data received at a client device from an online mapping system in response to a query from the client device includes vector and remote resource data. Vector data is rasterized by the client device to depict graphical elements that are easily described by mathematical formulas. Remote resource data includes digital map elements that are not easily described by vectors, but instead, must be relayed to the client device as either bitmaps or references (e.g., URLs) to remote resources that are resolved at the backend or the client device. This remote resource data is prefetched to a client device so that it will be available for subsequent mapping application searches without resolving a corresponding reference to the remote resource data for each search.
