Capturing geographic position

PowerApps has the fantastic ability to integrate with the location services that are provided by a mobile device using GPS or cellular information. With this service, we can determine the position of the device using latitude and longitude, as well as the direction the device is facing.

We determine the GPS location using the position that's relative to two imaginary lines running around the Earth. The first is the equator, which signifies 0° latitude, and gives us the division between the Northern and Southern hemispheres. The latitude value increases as you progress further north and decreases as you go further south, to a maximum value of 90. Therefore, the north pole has +90° latitude, and the south pole has -90° latitude.

The second imaginary line is at 0° longitude and is known as the prime meridian. This line dissects the Earth into the Western and Eastern hemispheres. The longitude values increase and decrease as you move...
