At least 80% of all information being collected by enterprises includes geolocation data. The Bing Maps V8 library is a very large collection of JavaScript code that allows web developers to place a map on a webpage, query for data, and manipulate objects on a map, creating a geo-application. In Bing Maps V8 Succinctly, James McCaffrey takes readers through utilizing this library, from creating the simplest application that uses it, to mastering more advanced functions like creating color-gradient legends and custom-styled Infobox objects.
