In an earlier blog post titled "Develop location-aware, Metro style apps when your development system doesn’t have GPS", one option I presented for those wishing to develop high-precision location-based Windows Store apps is to hook up an external GPS to your computer.
Welcome to the RTFB (Reaching For Technology From Blogs) Episode 5 Blog. Guests on RTFB are given an opportunity to talk about their blogs. For this video, I interviewed John Mechalas about writing location aware apps:
Recently one of my colleagues interviewed me in a short video segment on the geolocation sensor in Windows 8, and one of the questions I was asked was whether there was an app that could tell the developer or the user if their system has a GPS or GNSS receiver in it.
Earlier this week I wrote about how to calculate the distance between two points in a location-aware app. Today, I am going to discuss a related topic: how to calculate the bearing between two points.
The HTML5 section within the Intel Developer Zone was updated just before the US Thanksgiving Holiday to release the new Intel® HTML5 Development Environment Beta and I tried out a few of the sample apps. It took me about fifteen minutes to get one of the samples packaged into an .apk file and running on my Android tablet.
If you are developing a location-aware application, you may reach a point where you need to know the distance between two geographic locations, such as the user's current position and some destination point like a city, airport, or attraction. The Location API in Windows 8 and the LocationManager class in Android, however, report positions in latitude and longitude as do most global services that map geographic names to a position on the earth.

“Right there,” he thinks, “across from the pizza shop.”
