d) All measurements have been made and a diagram produced that shows the location of all the computers as well as the minimum spanning tree network. This will prove the cheapest path for the cables to be placed.

This diagram or network could show the foot paths around a large zoo, with the nodes of the network being the exhibits and the lines being the paths. This diagram is an overhead or aerial view of the zoo and can be used as a map that can be supplied for visitors. The numbers on the diagram show the distance in meters between the exhibits, by the paths.

Surveying is an important part of everyday life, as without it nothing could have been built in the correct place, and no one would know who owned what land, it can also be used to answer questions

Northing (target) = Northing (set up) + (1(cos ¦È))

To plot the points of a selected area, for example a football field, a central point is chosen and used as the set up point. A GPS can then be used to find the bearings of the set up point, a person then takes the reflector pole to each point and a measurement is taken using the theodolite. Using the above-mentioned formulas the horizontal distance can be worked out, the height of the ground (above sea level) can also be found out, then using Pythagoras the slope distance can be worked out. The Easting¡¯s and Northing¡¯s can be seen in figure 2 using the relative formula.

Height = height on ground (set up) + Instrument height (set up) + (slope distance X cos (vertical angle)) ¨C height observation pole.
