I am trying to work out how to convert between distances to lat lons.

The user selects a point on the map, and I want to find out the lat/lon that
is a certain distance North,
South, East or West of that point.

The distance may be specified in feet/ metres or miles, although I could do
these conversions programmatically...

I have had a look through the API, and the only way I can see to achive this
is to use the Geo class to do kmToAngle(double km), then
Geo.degrees(<result>) However, I'm not sure if this actually does what I
need or not...

Any suggestions would be great!
