GIS Questions and Answers – Theoretical Models of GIS

This set of GIS Multiple Choice Questions & Answers (MCQs) focuses on “Theoretical Models of GIS”.

1. Who suggested an alternative classification which recognises three major components in its characterization of GIS?
a) Peuquet
b) Burrough
c) Marble
d) Bracken and Webster
View Answer

Answer: d
Explanation: Bracken and Webster (1989) suggest an alternative classification which recognises three major components in its characterization of GIS. They are the problem-processor model, database model and interface model.

2. Which among the following is not one of the four functional elements to address the
GIS technology outlined by Bracken and Webster?
a) Database Approach
b) Process-Oriented Approach
c) Output-Oriented Approach
d) Toolbox Approach.
View Answer

Answer: c
Explanation: Bracken and Webster (1987) outlined four functional elements to address the GIS technology. They are database approach, the process-oriented approach, an application oriented approach, and toolbox approach.

3. Which approach stresses the ability of the underlying data structures to contain complex geographical data?
a) Database Approach
b) Application Oriented Approach
c) Process-Oriented Approach
d) Toolbox Approach
View Answer

Answer: a
Explanation: First approach by Bracken and Webster was database approach. Database approach stresses the ability of the underlying data structures to contain complex geographical data.

4. Which approach focuses on the sequence of system elements used by an analyst running an application?
a) Database Approach
b) Application Oriented Approach
c) Process-Oriented Approach
d) Toolbox Approach
View Answer

Answer: c
Explanation: The second approach put forward by Bracken and Webster was process-oriented approach and this approach focuses on the sequence of system elements used by an analyst running an application.

5. Conceptual models make no statement about the nature of the data representation. Is this statement true or false?
a) True
b) False
View Answer

Answer: a
Explanation: Conceptual models tend only to address aspects of the operation or composition of GIS systems. They make no statement about the nature of the data representation.

6. Which approach defines GIS based on the kinds of information manipulated by the system?
a) Database Approach
b) Application Oriented Approach
c) Process-Oriented Approach
d) Toolbox Approach
View Answer

Answer: b
Explanation: An application oriented approach defines GIS based on the kinds of information manipulated by the system and the utility of the derived information produced by the system.

7. The toolbox approach emphasis as the software components and algorithms that should be contained in a GIS. Is this statement true or false?
a) True
b) False
View Answer

Answer: a
Explanation: An application oriented approach defines GIS based on the kinds of information manipulated by the system and the utility of the derived information produced by the system while the toolbox approach emphasis as the software components and algorithms that should be contained in a GIS.

8. The fundamental classes of operations performed by a GIS have been characterised as:
a) Map Analysis
b) Mapping
c) Map Algorithm
d) Map Algebra
View Answer

Answer: d
Explanation: The fundamental classes of operations performed by a GIS have been characterised as ‘map algebra’ in which context primitive operations of map analysis can be seen as analogous to traditional mathematical operations.

9. Overlay operations involve the combination of two or more maps according to boolean conditions and may result in the delineation of:
a) new points
b) new coordinates
c) new locations
d) new boundaries
View Answer

Answer: d
Explanation: The ‘classes of analytical operation’ are divided into reclassification, overlay, distance/connectivity measurement and neighbourhood characterisation of the data. The overlay operations can be identified as the combination of two or more maps according to boolean conditions and may result in the delineation of new boundaries.

10. Neighbourhood characterisation of the data includes the values to a location, summary and mean measures of a variable and smoothing/enhancement filters. Such manipulation operations have become known as:
a) mapping
b) modelling
c) cartographic modelling
d) digital modelling
View Answer

Answer: c
Explanation: Neighbourhood characterisation involves the values to a location both summary and mean measures of a variable, and include smoothing and enhancement filters. Sequences or such manipulation operations have become known as ‘cartographic modelling’.
