Cocoa touch class to create airspace boundary images

We have a requirement for a cocoa class to do two things;

1. Create UIImage's of airspace boundaries. A method will return an image, plus the lat/long of the image origin.

2. 'hit test' a point (lat,long,altitude) to see if a point is contained within, and which boundaries it is contained within. This method will return an NSArray objects which contain the point.

These images will comprise of a sequence of straight lines and arc segments which when joined joined together form a shape. This shapes needs to be colour coded depending on its type, and partially shaded on the inside. A method will be provided which will map between the map projection and coordinate space (lat/long to x,y).

These images will then be overlaid on an existing map in an existing application. These maps have different projections, but the method to map x,y to lat/long (and the reverse) will take this into account.

The input data will be comprised of a series of CoreData objects. The source data for these objects is attached. The completed product does not need to import or create the objects (but you will need to do this in some way to test probably). The part of the applicable object model will be provided.

The code needs to be thread safe - the images will be generated on a background thread. The hit test code needs to be thread safe - it will be called on a background thread.

The input data & specification to create the objects is attached.
