Let me clarify,
I didnt mean just doing the formula
in script, I meant to process the array and sort it within server side
_javascript_.

Alan,

Have you thought of
sever side scripting?
I did a similar test
a while back where the array was passed into server side _javascript_ and it did
the calcs very fast

Distance Calculation is no problem, that works.

Hi Richard,
How is the list of locations generated and what
do they represent? how are you using them in your
program?
Just wondering, why is it you want to store
iving away "proprietary secrets" or
not to do so :P

Hey Daniel!
What database are you using? I know MySQL can do the trigonometric
functions in a select statement and you could order your result from
the database...
Doing trig functions is pretty gross efficiency wise. You might want
to store some of the functions that aren't going to change in
Thats a neat idea having the lookup tables, very very cool idea (:
