GMN621S
Question 1
Needs assessment is the first phase in the GISplanning and implementation cycle.
a) In your own words, describe the purpose of a needs assessment exercise.
(6)
b) Name and discuss the three main outputs of a needs assessment exercise.
(6)
c) Give two examples each of guiding questions that you would ask during a needs
assessment at three different levels of functions/management.
(6)
[18)
Question 2
The establishment of a GIS is a complex process which needs careful planning, based on a
thorough analysis of the respective institution and its requirements. This is influenced by the
type, purpose, and level of GISimplementation.
List four main types of GIS implementation levels in an organisation. For each, explain what
reasons could trigger the "Thinking about Implementing a GIS" at that level.
(8)
[8]
Question 3
The Logical Framework is an approach to project planning that was developed as a tool for
detailed planning with clearly defined objectives that can be measured by using appropriate
indicators. List the ten (10) in the development of a logical framework in their correct logical
sequence. (No explanations please).

Question 4
During the physical design stage in GIS planning, three important system requirements aspects will
influence how the GISwill eventually function.
4.1 Explain what influences these three aspects.
(3)
4.2 When choosing a Client-server architecture, what factors would you consider in arriving
at the right choice?
(2)
4.3 In the past, GISdata storage was a very big challenge compared to today. Why was this a
problem and how has it suddenly not become a major issue anymore?
(3)
[8]
Question 5
The quality of a GIS analysis depends on the quality of data and the skills of the person doing the
analysis.
5.1 Briefly explain the four main types of spatial errors that are possible in GIS.
(8)
5.2 Explain the three common logical models for GIS Database designs.
(6)

Question 6
Namibia is busy implementing a National Spatial Data Infrastructure (NSDI) Policy and the Namibia
Statistics Agency (NSA) is mandated by the Statistics Act, No. 9 of 2011 to implement this.
6.1 Outline the relevance/importance issues of implementing the NSDIin Namibia.
(8)
6.2 Define what you understand by spatial data infrastructure (SDI)and name two types.
(2)
6.3 A Spatial Data Infrastructure (SDI)facilitates and coordinates the exchange and sharing
of spatial data between key stakeholders in a spatial data community. Explain three
critical success factors of implementing a National Spatial Data Infrastructure.

Question 7
7.1 What is a "B/C Ratio"? What does the abbreviation stand for and what is the b/C Ratio (3)
used for? (Or, in other words: What does the B/C Ratio indicate in an economic project
analysis?
7.2 List the various working steps, which are required to produce a B/C ratio in their correct (8)
sequence. Briefly explain each step with one or two short sentences. Note: Just follow
exactly the procedure that was used for the National Park Exercise.
Question 8
8.1 Let us assume that one of the important regular outputs of your GISwill be thematic
maps of an area which measures exactly 400 km in North-South and 270 km in East-
West direction. Let us also assume that you have a printer that can only print up to a
maximum format of DIN A3 (42 cm x 29.7 cm) and that a strip of 1 cm on all four sides
of the A3 sheet cannot be printed. What would be the maximum scale at which you
could print these maps, showing the entire 400 km x 270 km area on one DIN A3 sheet?
Note: A correct final figure result will only be counted if is accompanied by a
reproducible and correct calculation.
(4)
8.2 A typical soccer field has an area of about 70 m x 100 m.
a) How big is that soccer field in square meters (sq. m)?
(1)
b) How big is that soccer field in hectares (ha)?
(1)
c) How big is that soccer field in a square kilometre (sq. km)?
(1)
d) How big will that soccer field be on a map 1: 25,000? (Please give length and width in
mm and the map area in sq. mm!)

e) According to cartographic rules, the minimum size of a polygon should be 25 square
millimetres (sq. mm). Assuming this as the 'minimum displayable area', would a map
scale of 1: 15,000 be sufficient to display the soccer field correctly?
For all questions, please note that a correct result will only be counted if supported by
a reproducible and correct calculation! Hence, please do PRESENTyour calculation!
