This set of GIS Multiple Choice Questions & Answers (MCQs) focuses on “GIS Contribution Disciplines”.
1. GIS has been called an _______ because of the potential it offers for the wide variety of disciplines dealing with spatial data.
a) Innovative Technology
b) Enabling Technology
c) Helpful Technology
d) New Generation Technology
View Answer
Explanation: GIS is convergence of technological fields and traditional disciplines. Many related fields of study provide techniques which make up GIS. These related fields emphasise data collections while
GIS brings them together by emphasising integration, modelling and analysis. Thus GIS often claims to be the science of spatial information.
2. What is cartography concerned with?
a) Display of spatial information
b) Analysis of spatial information
c) Tabulation of data
d) Storage of information
View Answer
Explanation: Cartography is concerned with display of spatial information and is now the main source of input data for GIS and has a long tradition in the design of maps which is an important form of GIS output.
3. Remote Sensing is a source of geographical data by providing digital images derived from space and the air. True of false?
a) True
b) False
View Answer
Explanation: Remote sensing provides techniques for data collection and processing anywhere on the Earth at a low cost and consistent update potential.
4. What method can be used to collect high quality data on positions of cadastral objects like land parcel, building and topography?
a) Observation
b) Surveying
c) Prediction
d) Calculation
View Answer
Explanation: Surveying and Photogrammetry provide high quality data on positions of cadastral objects like land parcel and building, and topography. Aerial photogrammetry deals with the photographs taken by an aerial camera on board aircraft at different altitudes.
5. What is the source of digital data?
a) Digital Pictures
b) Digital Imageries
c) Digital Photos
d) Digital Orthophotos
View Answer
Explanation: Digital orthophotos provide the source of digital data. These products are scanned air-photos that have been rectified to eliminate displacement caused by variable elevation of the ground surface and the tilt of the camera.
6. The user may abstract information on land use, vegetation type and other aspects of the landscape from the photograph. True or false?
a) True
b) False
View Answer
Explanation: Properly registered with other digital data sets, digital orthophotos can be used directly as backdrops for vector data or to provide a base-map for onscreen digitising. The user may abstract information on land use, vegetation type and other aspects of the landscape from the photograph.
7. What is used as a platform which provides software, techniques for data input, display, visualisation and representation, particularly in 3-dimensions?
a) Word
b) Computer Assisted Design (CAD)
c) Paint
d) Sketch up
View Answer
Explanation: Computer Assisted Design (CAD) provides software, techniques for data input, display and visualisation, and representation, particularly in 3-dimensions. Advances in computer graphics provide hardware and software for handling and displaying graphic objects.
8. Which system contributes methods for representing data in digital form and procedures for system design and update?
a) Data Representation System
b) Computer Management System
c) Data Base Management System
d) Digital Data System
View Answer
Explanation: Advances in computer graphics provide hardware and software for handling and displaying graphic objects. Data Base Management System (DBMS) contributes methods for representing data in digital form and procedures for system design and update.
9. Artificial intelligence (AI) uses the computer to make choices based on available data in a way that is seen to enhance the human intelligence and:
a) calculation
b) drawing skills
c) decision making
d) tabulation
View Answer
Explanation: Using AI, computer can act as an “expert” in such functions as designing maps, generalising map features and classification.
10. What is important in understanding issues of error, quality and uncertainty in GIS data?
a) Software
b) Statistics
c) Repeated checking
d) Thorough Analysis
View Answer
Explanation: Statistics is used to build models and perform spatial data analysis in GIS. Statistics is also important in understanding issues of error, quality and uncertainty in GIS data.
