This set of GIS Multiple Choice Questions & Answers (MCQs) focuses on “GIS Architecture”.
1. According to the definition proposed by Marble and Peuquet (1983), GIS deals with:
a) space-time data
b) space-distance data
c) distance-time data
d) space-location data
View Answer
Explanation: According to the definition proposed by Marble and Peuquet (1983), GIS deals with space-time data, and often but not necessarily, employs computer hardware and software. GIS can be understood as the subsystem nature within the framework of a main system.
2. The fourth subsystem output/reporting subsystem in GIS provides a way for the user to see the data in the form of diagrams, maps, and/or tables.. True or false?
a) True
b) False
View Answer
Explanation: GIS has the following generic subsystems:
(i) A data input subsystem which is also called data capture subsystem
(ii) A data storage and retrieval subsystem
(iii) A data manipulation and analysis subsystem
(iv) A reporting subsystem.
3. What function is performed by the data input/capture subsystem of GIS?
a) Retrieval of Data Elements
b) Storage of Data Elements
c) Acquiring Data
d) Transformation of Data
View Answer
Explanation: The data input/capture subsystem provides operational functions for acquiring data. The data management or data storage and retrieval subsystem stores and retrieves the data elements. The manipulation and analysis subsystem handles the transformation of data from one form to another and derivation of information from the data.
4. Which one among the following options is not an important component of Geographical Information System?
a) Organisational Setup
b) Map
c) Computer Hardware
d) Application Software Modules
View Answer
Explanation: Geographical Information Systems have three important components namely, computer hardware, sets of application software modules, and a proper organisational setup. These three components need to be in balance if the system is to function satisfactorily.
5. Which is the most important hardware unit of a GIS?
a) Printer
b) Plotter
c) Digitiser
d) Control Processing Unit
View Answer
Explanation: The general hardware components of a GIS include control processing unit which is linked to mass storage units, such as, hard disk drives and tape drives, peripherals such as digitiser or scanner, printer or plotter and Visual Display Unit.
6. The digital representation can never be of a higher accuracy than the input data. True or false?
a) True
b) False
View Answer
Explanation: The digital representation can never be of a higher accuracy than the input data, although the mechanisms for its handling will frequently be capable of greater precision than that achieved during data collection.
7. What is known as the process of identifying and gathering the data?
a) Data Identification
b) Data Gathering
c) Data Acquisition
d) Data Collection
View Answer
Explanation: Data acquisition is the process of identifying and gathering the data required for any given application. This typically involves a number of procedures. One procedure might be to gather new data by preparing large-scale maps of natural vegetation from field observations.
8. The functions of database management govern the creation of an access to the:
a) database itself
b) CPU
c) internet
d) scanner
View Answer
Explanation: The functions of database management govern the creation of an access to the database itself. These functions provide consistent methods for data entry, update, deletion, and retrieval.
9. What is the phase where final outputs from the GIS are created?
a) Data Structure Conversion,
b) Product Generation
c) Statistical Analysis
d) Reclassification
View Answer
Explanation: The output products might include statistical reports, maps, and graphics of various kinds. Some of these products are softcopy images and hardcopy.
10. Which among the following is not a data input and output device used in GIS?
a) Plotter
b) Processor
c) Printer
d) Scanner
View Answer
Explanation: Data input and output devices, like digitisers, scanners, keyboards, printers and plotters are used in GIS.
