Web mapping distance determination using cache

A computing system comprising:

• a processor configured to
• receive a processing request from a software application for a route distance between a source location and a target location on a geographical web map,
• identify a sub-area of the geographical web map in which the source location is geographically located and identify a sub-area of the geographical web map in which the target location is geographically located, and
• identify, via a cache, a distance determination between a similarly-located source location included in the sub-area of the source location and a similarly-located target location included in the sub-area of the target location, which is previously determined by a web mapping service;
• and
• an output configured to output route guidance to the software application based on the previous distance determination between the similarly-located source location and the similarly-located target location determined by the web mapping service in response to the processing request.

A non-transitory computer readable medium having stored therein instructions that when executed cause a computer to perform a method comprising:

• receiving a processing request from a software application for a route distance between a source location and a target location on a geographical web map;
• identifying a sub-area of the geographical web map in which the source location is geographically located and a sub-area of the geographical web map in which the target location is geographically located;
• identifying, via a cache, a distance determination between a similarly-located source location included in the sub-area of the source location and a similarly-located target location included in the sub-area of the target location, which is previously determined by a web mapping service;
• and
• outputting route guidance to the field service software application based on the previous distance determination between the similarly-located source location and the similarly-located target location determined by the web mapping service in response to the processing request.
