    I have a bunch of locations (of chapels across the US) and I need to make it so the user can "find the nearest location" of a chapel. I'm not sure how I should go about doing this. The website uses Joomla (I'm not the one who thought of using it... I hate it!), so if there are any extensions you know of that would let me do that I would appreciate it. If there are any other ways of doing it, I'll take those too. Little to no cost would be great, too.

    You could use the google maps geocode function, pass the addresses and get a latitude and longitude for each address.... then compute the hypotenuse of the differences and select the lowest value of the set... that would be your closest chapel. Across a small enough area polar coordinates can be used to approximate a rectangular coordinate system.

    This will take some learning, but I'll see what I can do. I'll probably try angelwatt's idea first.

    Thanks for the great graphic :)
