tck_17 Posted May 13, 2012 Posted May 13, 2012 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. 93.8-88.9=4.9 50/49=1.0204081 1.0204081 x 11= 11.22 Where did "11" come from? I just don't quite understand. Quote
ReMark Posted May 13, 2012 Posted May 13, 2012 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? Quote
