Which got me wondering what the largest area is on a UK OS (25/50) map
with no contours printed.
This was done in The Angry Corrie, abeit they were looking for a blank
terrestrial grid square. It then made it onto the BBC website and
other places. I think the blankest square found on OS 1:50k had a
drainage ditch and a contour.
