I am working with OSM data, and would like to be able to spec out 5 mile bounding boxes from certain GPS points.
After research into this problem, I am to understand that each degree of latitude is approximately 69 miles (111 kilometers) apart with a slight variance (68.703 - 69.407 miles) between the equator and the poles, and that each degree of longitude is widest at the equator @ 69.172 miles (111.321 kilometers) and gradually shrinks to zero at the poles. : ) :) So what does this mean? If I want to take a input point, like lets say, 167.9 lat -29.1 lon or -63.1 18.1 Can someone say with authority, what the 'calculus' would be to definitivly construct a NSWE bounding box with a 5 mile radius around those points?.... that would be basically close enough or accurate? :) -- Be Yourself @ mail.com!
