Question 3
3.1. You are a consultant hired to collect data for a GISfor urban development monitoring.
As part of your task, you must determine the appropriate scale and corresponding
primary data sources. Assuming you have to produce a map for a town council. What
would be the scale of the map if a 120 m x 160 m erf is 6 cm x 8 cm on the map?
(2)
3.2. Now that you have determined the scale of your map in 3.1, what would be the area of
a disposal site in cm2 if its dimension is 2.4 km by 0.8 km on the ground?
(6)
3.3. Assume a person offers you a three-hectare (i.e. 3 Ha) plot to buy and then shows you
the location of the plot on a map with a map scale of 1:2000. The plot which he shows
you is a rectangular polygon and measures 9 cm x 8 cm on the map. By how much bigger
or smaller (in ha) is this plot on the ground?
