GEO UTILITIES

This repository contains some code that can be used on iOS for some basic stuff not currently available in Apple's CoreLocation framework.

CLHeading+Text

This category on CLHeading can convert a heading to its textual equivalent, e.g. 0 degrees -> 'N', 90 degrees -> 'E', etc. There are 4 levels which you can use to indicate the desired precision (N vs. NNE).

CLLocation+Navigation

This category on CLLocation adds method to do distance calculations, as well as calculations to determine the direction (bearing) to follow to go from A to B. The methods are based on the info found at www.movable-type.co.uk/scripts/latlong.html.
