Brilliant Alistair, many thanks.
It seems churlish to suggest improvements, but you did ask:
Some way of relating time/height with position on the map ?


Thanks, I'm glad you like it.

In terms of improvements, I had been thinking much the same thing - maybe a
time slider that would move markers on the map and the graph?

It also really needs a way to read accurate values off the graph - "Does
this qualify for Silver Height or not?"

Alistair
