Hi..My question is about the computation of the interpolations..I was reading the other threads and the explanations are confusing..
I believe car5858 followed the example #2.
My question is with the sample from the project booklet.
1.0204081 x 11= 11.22
Where did "11" come from? I just don't quite understand.

Having read and reread Car5858's explanation on how to interpolate contours I can find no fault. Wouldn't the "11" be the distance to the required spot elevation?
