Jedd,

i haven't written them by any means... i actually don't know anything about them! The purpose of my post was to try and get some suggestions as to things i should be looking at with regard to planning how i am going to achieve my aims.

Can you provide some further info about the MySQL geometry type and i will do some further reading for definate, even if i don't end up using them its worth being aware they exist... i'm quite new to php / mysql side of webdesign and don't get to do as much of it as i do static xhtml / css so i have holes in my knowledge!

Often its not actually knowing how to do something that matters but more knowing that something is possible because then at least you know you can go and research it!
