use pythagoras theorem to get the latitude change distance.
one degree of latitude is approximately 69 miles (111 kilometers)

Complexity of the algorithm will depend on what type of surface is assumed and to what degree inaccuracies are acceptable.

On a plane the solution is fairly simple and requires only classical geometry and basic trigonometry.

On a sphere, spherical trigonometry is required to find an exact solution.  However, if the area of interest is limited to a shell fragment bounded by the horizon visible from a 100 foot structure - then the area of interest is a very slightly curved circular shell fragment with a radius of 19.6 Km, and a planar approximation will probably suffice.
