Question 1

GIS is a specialised tool for handling&#10;A) maps&#10;B) numbers&#10;C) texts&#10;D) graphics

Accepted Answer

GIS stands for Geographic Information System, which is a tool for handling geographic data and creating maps. While GIS does involve numbers, texts, and graphics, the primary focus is on spatial information and its analysis.

Question 2

Characteristics of a GIS that distinguish it from other kinds of computerised systems include:&#10;A) a GIS can produce reports&#10;B) a GIS supports statistical analysis&#10;C) a GIS provides capabilities for data management&#10;D) a GIS provides spatial analysis functions

Accepted Answer

A GIS is distinct because it provides spatial analysis functions, allowing users to analyze and visualize geographic data in ways that other computerized systems typically do not.

Question 3

Spatial data describe&#10;A) what geographical features are&#10;B) where geographical features are located&#10;C) geometry of geographical features&#10;D) both location and attribute of geographical features

Accepted Answer

Spatial data includes information on both the location and attributes of geographical features, such as the geometry of the feature and its associated data such as names, population, etc.

Question 4

A GIS comprises&#10;A) hardware and software&#10;B) hardware, software and data&#10;C) hardware, software, data and people&#10;D) hardware, software, data, people and procedures

Accepted Answer

A GIS includes not only hardware and software, but also data, people, and procedures. All of these components are necessary to effectively capture, store, analyze, and display geographic information. The hardware and software are the tools used to access and manipulate data, while the data is the information being processed. The people involved in a GIS may include a variety of professionals such as GIS analysts, database administrators, cartographers, and end-users, who all work together to ensure that the GIS is functioning as required. Lastly, the procedures (i.e. standards, protocols, and workflows) serve as guidelines for using the software, managing data, and completing tasks in a consistent and efficient way.

Question 5

The six functional components of GIS include&#10;A) hardware, software, data, people, organisations and procedures&#10;B) overlay analysis, buffer, spatial query, network analysis, surface analysis and image processing&#10;C) spatial data input, data storage and management, data manipulation, data analysis, data output and interfaces&#10;D) graphic user interfaces, command-line interfaces, programming interfaces, tools, data management and people

Accepted Answer

The six functional components of GIS are spatial data input, data storage and management, data manipulation, data analysis, data output and interfaces. Option A lists the components of GIS in general, Option B lists six analytical functions of GIS, and Option D includes interfaces, tools, data management and people, but there is no mention of the other functional components of GIS.

Question 6

Which of the following is TRUE?&#10;A) GIS is rooted in computer sciences.&#10;B) GIS is rooted in computer mapping.&#10;C) GIS is rooted in land use inventory.&#10;D) GIS is rooted in remote sensing.

Accepted Answer

GIS, or Geographic Information Systems, is primarily rooted in computer mapping, which involves the use of computers to create, store, and analyze maps and spatial data.

Question 7

To analyse the spatial associations between rainfall, elevation and vegetation, which GIS function should you use?&#10;A) query&#10;B) buffering&#10;C) overlay analysis&#10;D) surface analysis

Accepted Answer

Overlay analysis is the most appropriate function for analysing the spatial associations between rainfall, elevation, and vegetation as it allows for the combination of multiple layers to create new output layers. This can be used to identify areas where specific combinations of variables exist, such as areas with high rainfall and high vegetation cover at high elevations. Query and buffering functions are more suitable for selecting or isolating specific features within a layer, while surface analysis functions are primarily used for modelling terrain or elevation data.

Question 8

A buffer might represent which of the following?&#10;A) the location of wetland&#10;B) the dispersion of pollutants&#10;C) the boundaries of a forest stand&#10;D) the path a bird takes when flying south for the winter

Accepted Answer

A buffer is usually used to represent the dispersion of pollutants, such as a buffer zone created around a polluted water source to help prevent the spreading of the pollutants. It is not typically used to represent the location of wetlands, boundaries of a forest stand, or the path of a bird.

Question 9

Descriptive analysis with GIS is to&#10;A) describe what is where or where is what&#10;B) explain what should be where or where might be what&#10;C) prioritise decision alternatives&#10;D) develop what if scenarios

Accepted Answer

Descriptive analysis with GIS is used to describe and depict the spatial distribution of data, revealing patterns and relationships between different features or phenomena on a map. This can involve overlaying different layers of data to create a visual representation of where different things are located, or performing statistical analysis to describe the characteristics of different areas. Option B is more closely related to predictive analysis, which uses GIS to model future scenarios or predict where certain things might be located based on current patterns. Option C involves making decisions based on the analysis, while option D pertains to modelling different scenarios and outcomes based on different assumptions.

Question 10

Predictive analysis with GIS is to&#10;A) describe what is where or where is what&#10;B) explain why it is there&#10;C) describe what should be where or where might be what&#10;D) prioritise decision alternatives

Accepted Answer

Predictive analysis with GIS involves using data and statistical models to make predictions about future locations or events. This can include predicting where certain natural resources may be found, or where certain types of crime are likely to occur. The focus is on predicting what should be where, or where something might be located.
