thanks Pegasus. Really appreciated.

Can people keep an eye out for a Green Scurion on a Green Petzl Vertex helmet with pen style backup light on the helmet. The battery pack of the scurion has reflecctive tape on the back also. I either (like a right muppet) left it on the roof of the car in Pindale near Castelton and drove back...

I'm new to all this surveying and mapping. I've got a centreline on survex and am currently drawing up the passage detail. Is there an easy way to overlay the centre line onto google earth or google maps? Preferably if there is a free option, even better. jess
