Here are GIS MCQs (Chapterwise).
1. What is the term used to refer to the process of making maps using a computer?
a) GIS
b) Digital Scanning
c) Digital Mapping
d) Mapping using a Computer
View Answer
Explanation: Today, the term GIS tends to be applied whenever geographical information in digital form is manipulated, whatever be the purpose of that manipulation. Thus using a computer to make a map is referred to as ‘GIS’.
2. Who is the father of Canada GIS?
a) David Bickmore
b) McHarg
c) Ray Boyle
d) Roger Tomlin
View Answer
Explanation: Roger Tomlin the father of Canada GIS is credited with visualising the need for computers to perform certain simple but labour-intensive tasks associated with Canada Land Inventory.
3. What is the purpose of Resource Information System (RIS)?
a) Weather Management
b) Agricultural Management
c) Oceanography
d) Population Forecasting
View Answer
Explanation: The Resource Information System (RIS) for agricultural Management has to be considered multidimensional with attribute dimension, spatial dimension and temporal dimension. Geographic Information System (GIS) offers capabilities of integrating multi-sector, multi-level and multi-period database.
4. Which step in GIS comprises of operations such as reformatting, tabulation, report generation, and mapping?
a) Post Processing
b) Pre Processing
c) Analysis
d) Capturing
View Answer
Explanation: GIS is a general-purpose technology for handling geographic data in digital form, and satisfying post processing of results including such operations as reformatting, tabulation, report generation, and mapping.
5. What is the basic output of GIS or spatial data analysis system?
a) Software
b) Numbers
c) Locations
d) Map
View Answer
Explanation: GIS is much more advanced than Computer Aided Design (CAD) or any other spatial data system. The basic output of GIS or spatial data analysis system is a map. The need to analyse maps to compare and contrast patterns of earth related phenomena, is confirmed by the long standing tradition of doing so with traditional maps.
6. What function is performed by the data input/capture subsystem of GIS?
a) Transformation of Data
b) Acquiring Data
c) Storage of Data Elements
d) Retrieval of Data Elements
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.
7. What is the other name for 4-D GIS?
a) Temporal GIS
b) 3 plus 1 GIS
c) Fourth GIS
d) Modern GIS
View Answer
Explanation: 4-D GIS is also known as Temporal GIS. It is the fourth category of GIS. In this case, the fourth dimension namely time is introduced. The kinds of GIS applications depending on time are regarded as temporal GIS systems.
8. What is an entity or a point/line which is represented by two values in GIS?
a) XY GIS
b) XZ GIS
c) YZ GIS
d) 2-D GIS
View Answer
Explanation: If an entity or a point/line is represented by two values, for example, x-coordinate y-coordinate, thus it is said to be 2-D GIS.
9. Which is the fundamental method of representing GIS entities?
a) Mapping Method
b) Drawing Method
c) Raster Method
d) GIS Method
View Answer
Explanation: There are two fundamental methods of representing geographical entities. They are Raster method and Vector method.
10. Which option is not a disadvantage of raster data representation?
a) Decrease of the reliability of area
b) Need for large storage capacity
c) Reduced spatial accuracy
d) Relatively easy to conceptualise
View Answer
Explanation: The major disadvantages of the raster data structure are a reduced spatial accuracy, decrease of the reliability of area and distance measures, and the need for large storage capacity associated with having to record every grid cell as a numerical value.
11. Which among the following is not a continuous data?
a) Population
b) Cliffs
c) Hills
d) Ridges
View Answer
Explanation: All discrete features have a zero dimensionality but have some spatial dimension. The natural features like hills, ridges and cliffs can be described by their locations, the area they occupy, and how they are oriented with the addition of the third dimension. All these are considered as continuous surface features.
12. What are the two criteria based on which all the maps are broadly classified?
a) Political Boundaries and Color
b) Climate and Temperature
c) Scale and Contents
d) Size and Theme
View Answer
Explanation: On the basis of the scale, the maps are classified as either a small scale map or a large scale map. On the basis of the content, maps are classified either as physical maps or cultural maps.
13. What is the other name for geographic coordinate system?
a) Rectangular Coordinate System
b) Parallel Coordinate System
c) Latitude and Longitude System
d) Spherical Grid System
View Answer
Explanation: The lines of latitude run parallel to one another and lie at right angles to lines of longitude. Each line of latitude represents the circle rounding the globe. The circle of greatest circumference is called the equator and will be at equidistant from the poles. This system is also called as spherical grid system.
14. What is the combination of any two map projections?
a) Hybrid Projection
b) Mixed Projection
c) Intersecting Projection
d) Perfect Projection
View Answer
Explanation: A combination of any two of the cylindrical, azimuthal and conical projections forms a hybrid projection.
15. Which type of map projection is best suited for use as regional or hemispheric maps, but rarely for a complete world map?
a) Cylindrical Map Projection
b) Equivalent Map Projection
c) Conical Map Projection
d) Azimuthal Map Projection
View Answer
Explanation: The distortion in a conic map makes it inappropriate for use as a map of the entire Earth but it can be used for temperate regions, weather maps, climate projections, etc.
16. Which type of projection portrays a portion of the earth’s surface on the developed surface of a secant cone?
a) Lambert Conical Orthomorphic Projection
b) Oblique Mercator
c) Mercator
d) Transverse Mercator
View Answer
Explanation: When using two standard parallels, in the area between these parallels, the map scale will be too small and in the area outside the parallels it will be too great.
17. What type of values is used in grid maps?
a) Varying Values
b) Semi-Angular Values
c) Linear Values
d) Angular Values
View Answer
Explanation: A Grid system has certain advantages over the use of geographical coordinates. Firstly, every grid square is of the same size and shape. Secondly, linear values can be used rather than angular values.
18. What is the most essential component of a GIS?
a) Graphical Representation
b) Information Database
c) Software
d) Satellite
View Answer
Explanation: The information database is developed by capturing information from different sources like topographical maps, thematic maps, and cadastral maps, in analogue form, remotely sensed images in digital form and so on.
19. Which methods are used to derive images that provide spatial information and major data as an input to GIS?
a) Optical and digital remote sensing systems
b) Analysis by human eye
c) Platform based remote sensing systems
d) Ground based remote sensing systems
View Answer
Explanation: Raw geographical data are available in many different analogue or digital forms like maps, aerial photographs, and satellite images. Images derived from optical and digital remote sensing systems mounted in aircraft and satellites provide much spatial information and major data as an input to GIS.
