involved. About 908 bus road traffic crashes caused injuries to the occupants. The
causes of this problem have been researched and debated for a long time. You are part
of the team that is conducting a desktop analysis to determine the causes of this
problem. Develop a problem tree depicting the main problem, and three main causes
and for each of the main reasons/causes identify two sub-causes (2nd level) for the high
number of bus accidents.

Geoinformation Management
Question 6
GMN621S
You are a consultant hired to collect data for a GIS for urban development monitoring. As
part of your task, you are required to determine the appropriate scale and corresponding
primary data sources.
6.1 Assuming you must produce a map for a town planning firm. What would be the scale
of the map if a 60 m x 30 m erf is 20 mm x 10 mm on the map?
(2)
6.2 Now that you have determined the scale of your map, what would be the perimeter in
cm of a school sports field area on the map, if the perimeter on the ground is 900
meters?
(2)
6.3 Assume a person offers you a 7.9 Ha plot to buy and then shows you the location of the
plot on a map with the same scale as in (6.1). The plot which he shows you is a
rectangular polygon and measures 8 cm x 10 cm on the map. By how much bigger or
smaller (in ha) is this plot on the ground?
(4)
6.4 The maximum West-East extension of the NUSTpremises (including the Main Campus,
the Sub-Campus, and the Hotel School) is about 800 m, and the maximum north-south
extension is about 200 m. Can you print the entire NUST Campus premises on a single
DIN A 4 page at a scale of 1: 2500? (Note: A DIN A 4-page measures 210 mm x 297 mm)
Assume that 1 cm along all four edges cannot be printed) Please motivate your answer
with a comprehensible calculation.
