Based on the provided EDM data:

$3\mathrm{.}1.$ Reduce the EDM data, accounting for atmospheric effects, prism$/$instrument indexes and instrument scale factor to calculate the reduced slope distance to each location

$4.$ Based on the provided zenith angle data and EDM data:

$4\mathrm{.}1.$ Calculate the trigonometric height data for locations B and J

$4\mathrm{.}2.$ Calculate the height $($vertical length$)$ of the camera poles at locations B and J Zenith angle for station B is $305\mathrm{.}2416$ degrees and station j is $215\mathrm{.}2875$
