Derivation of Façade Equations The equations that the spreadsheet uses to reduce the data are easily derived. Starting with the three original taped measurements, c = Horizontal distance between theodolite locations. d A and d B are the horizontal perpendicular distances from base line to theodolite locations. = Vertical offset between theodolites From these we get δ = Horizontal offset =

Unformatted text preview: d B- d A = Angular offset = arcsin ( /c) L = distance AA' between A & B parallel to baseline = c 2- 2 For each target P we have, = horizontal angle at A from B to target = vertical angle at A from horizontal to target = horizontal angle at B from A to target = vertical angle at B from horizontal to target....
