RHCES Contour Interpolation

Input

Lower contour elevation EL_lo (m)

Upper contour elevation EL_hi (m)

Total horiz. distance lo→hi (m)

Distance from lo to point (m)

Contour interval CI (m)

Slope along line—

Rise to point—

Spot elevation—

Distance left to next contour—

Distance left to lower contour—

Method

Linear interpolation: EL_pt = EL_lo + (D_partial / D_total) · (EL_hi − EL_lo). Slope along the line = CI / D_total. Distance to next upper contour = (1 − fraction) · D_total.
