Question

how do i calculate contour line? here is one triangle of the contour map

Answer 1

yes

Answer 2

how did you get 42.5 below 40.5?

Answer 3

it was written down on my map

Answer 4

hmm doesnt make sense...
i find the scale factor

Answer 5

126 is the true height difference?

Answer 6

and i had to measure the triangle to find the elevation which i measured out to be 126

Answer 7

@chemENGINEER do you know how to do this?

Answer 8

the thing is i dont really understand your question...
maybe if i had the original question then i can do it

Answer 9

i measure the triangles 1:20" scale

Answer 10

i'll try and upload it tomorrow because its huge

Answer 11

it is contour interpolation @AbhimanyuPudi

Answer 12

the elevation from 42.5 to 40.5 is correct in w/c you got elevation=2

Answer 13

average slope = rise / run

Answer 14

what do i do next?

Answer 15

do i multiply the 2 by 126 and divide by 2?

Answer 16

hmm i think you need to give all the info or the whole prob and pictures here, look like theyre incomplete
