Calculating bounding box a certain distance away from a lat/long coordinate in Java

Question

Given a coordinate (lat, long), I am trying to calculate a square bounding box that is a given distance (e.g. 50km) away from the coordinate. So as input I have lat, long a

Answer 1

I wrote an article about finding the bounding coordinates:

The article explains the formulae and also provides a Java implementation. (It also shows why IronMan's formula for the min/max longitude is inaccurate.)
