This set of GIS Multiple Choice Questions & Answers (MCQs) focuses on “Theoretical Framework for GIS”.
1. Which among the following is not an example for spatial specific data structures?
a) Vector
b) Raster
c) Triangulated Irregular Network
d) Hierarchical Attribute
View Answer
Explanation: The idea of data representation used here should not be confused with work on specific data structures, either spatial, such as, vector, raster, triangulated irregular network, quad tree or attribute such as, hierarchical and relational which are mainly technical issues.
2. The geographic data-processing system outlined is not intended to be a description of any specific software system. True or false?
a) True
b) False
View Answer
Explanation: The geographic data-processing system outlined is not intended to be a description of any specific software system, but is a model of the processes which may operate with digital geographic data.
3. Software systems containing some capacity for input, manipulated and output digital spatial data in some form are considered to be _____ in the present context.
a) Dependable
b) Strong
c) GIS
d) Usable
View Answer
Explanation: Actual software systems may be identified which perform all or some of the principal transformations to a greater or lesser degree, but only those containing some capacity for input, manipulated and output digital spatial data in some form are considered to be ‘GIS’ in the present context.
4. What do we call the people seeking to understand the relationships between the world and the map?
a) Surveyors
b) Cartographers
c) Map makers
d) Software Engineers
View Answer
Explanation: Cartographers are the makers of maps. Cartographers work to understand the relationships between the world and the map as a model.
5. The process of analogue map production may be modelled as a series of transformations between the real world, raw data, the map, and the:
a) World
b) Locations on Earth
c) Data
d) Map Image
View Answer
Explanation: The digital map is related to the analogue map and we must modify and extend the existing theoretical structure to replace the paper map with a digital map sitting within a GIS. The process of analogue map production may be modelled as a series of transformations between the real world, raw data, the map, and the map image.
6. The significance of the traditional cartographic process is that they control the amount of information transmitted from one stage to the next.. True or false?
a) True
b) False
View Answer
Explanation: The process of analogue map production may be modelled as a series of transformations between the real world, raw data, the map, and the map image. The significance of these transformations is that they control the amount of information transmitted from one stage to the next.
7. The cartographer’s task is to devise the very best approximation to an ideal transformation involving a:
a) Reduction of Mistakes
b) Maximum of Data
c) Minimum of Information Loss
d) Increase of Accuracy
View Answer
Explanation: The cartographer’s task is to devise the very best approximation to an ‘ideal’ transformation involving a minimum of information loss. A detailed explanation of the ‘transformational’ view of digital cartography is given in Clarke (1990).
8. In the transformation based GIS operation, first transformation data are selected from the:
a) Real World
b) Virtual World
c) Graphic Data
d) Map
View Answer
Explanation: In the first transformation data are selected from the real word, as for example, surveying measurements or census data.
9. Within the system, a vast range of manipulation operations are available to further transform the data and store the results and these may be communicated as tabulated or graphic images by means of a:
a) print out
b) hardcopy or screen
c) presentation
d) drawing
View Answer
Explanation: In the system, operations are available to further transform the data and store the results. These may be communicated as tabulated or graphic images by means of a hardcopy or screen.
10. Who noted down the thematic and spatial characteristics in GIS?
a) Clarke
b) Berry
c) Tomlin
d) Webster
View Answer
Explanation: If the ‘thematic and spatial’ characteristics noted by Berry (1987) are to be understood, it is necessary for us to carefully consider the way in which the four transformations in GIS operations may affect the digital representation of the real-world objects.
