Some replies to comments below and perhaps I will have to find a way to clarify

comment on our topographical maps, we expect our contour lines to be at 10
or 20 metre (33 or 66 foot) intervals. Intervals of 122 metres would make
navigation that much more difficult.
-- The contour lines are actually at 80 foot intervals, with the numeric contour indication every 400 feet) The contour line interval is captured in the product description, but I'll see if I can make this read better.

and you mention 1:24,000 here. Are both correct?
---map is to 1:73,530; NG TOPO software will go down to 1:24,000 - it is meant to indicate that when using TOPO! software to estimate mileage, it is only as good as the software's capability.
