WP7 Code: Geofencing with the GeoLocation API and Rx

  Besides providing geographical coordinates, computing distances, and making reverse geocoding service requests Windows Phone 7 can also signal when it is moved outside of a perimeter. The buzzword for this scenario is Geofencing, and this post shows how to implement it (when the geofence is circular) with the WP7 GeoLocation API and Rx. An…

WP7 Code: Reverse GeoCoding with the Bing Maps Service

  My previous blog posts showed how to obtain location as an event stream from the Windows Phone 7 GeoLocation API, and how to translate lat/long position readings into distances. Here I show how to build an application that combines data from the phone’s geolocation subsystem with data from the cloud. In effect it is…

WP7 Code: Distance Computations with the GeoLocation API

  In my previous post I showed the most interesting code fragments for a location-aware Windows Phone 7 application. The code generates an event stream corresponding to location readings from the phone’s location subsystem. However, there are many applications that instead of lat/long readings need to compute the traveled distance (for example, when driving, biking,…

WP7 Code: Using the GeoLocation API

  I’m kicking off a series of blog posts focused on writing Windows Phone 7 code with one of the APIs that will probably attract many developers interested in getting their feet wet: GeoLocation. Building this code requires: The Windows Phone Developer Tools, fresh off the press as of September 16. The Windows Phone Development…
