Hi all, I am using PHP 5.3.9 and I am trying to figure out how to calculate the size of a bounding box based on the passed in coordinates of the 4 corners of a geographical map. The reason for this is that I need to check that the size/area of the bounding box is not larger than 20 Kilometres. The bounding box format is defined as:
$southwest_lat = $_GET['swlat']; $southwest_lng = $_GET['swlng']; $northeast_lat = $_GET['nelat']; $northeast_lng = $_GET['nelng']; Your help is much appreciated.
