7 Passage-Based Questions
Passage-Based Questions
Passage
A Geographical Information System is a system for capturing, storing, checking, integrating, manipulating, analysing and displaying data that are spatially referenced to the Earth. It draws its conceptual and methodological strength from many allied fields, including Computer Science, Statistics, Cartography and Remote Sensing. A GIS has five components working together: Hardware, Software, Data, People and Procedures, each contributing a distinct role, from the physical processing and storage equipment to the trained people who turn raw data into decisions.
- 1 mark(Based on the passage) According to the passage, what does a GIS do with data that are spatially referenced to the Earth?
(A) Only stores them(B) Captures, stores, checks, integrates, manipulates, analyses and displays them(C) Only displays them on a screen(D) Deletes duplicate records automatically
Passage
A buffer is a zone of a specified distance created around a point, line or area feature. This kind of analysis, called proximity analysis, is useful for finding out how much area or population is served, or denied, by a facility such as a hospital, a medical store or a park. In a case study of western Uttar Pradesh, buffers of 2, 4, 6, 8 and 10 kilometres were created around six cities with major hospitals: Saharanpur, Muzaffarnagar, Meerut, Ghaziabad, Gautam Budh Nagar and Aligarh. Areas closer to these cities were found to be better served, while people living farther away had to travel longer distances to reach medical services.
- 1 mark(Based on the passage) What does the passage call the kind of analysis a buffer operation performs?
(A) Network analysis(B) Overlay analysis(C) Proximity analysis(D) Digital Terrain analysis

Answer Key and Explanations
Direct Questions
- (C) The chapter defines Spatial Information Technology as an amalgamation of Remote Sensing, GPS, GIS, Digital Cartography and Database Management Systems.
- (A) The chapter states plainly that the word spatial is derived from space.
- (B) The chapter states that advance computing systems available since mid 1970’s enabled the processing of georeferenced information for GIS.
- (D) The chapter names exactly twelve fields: Computer Science, Statistics, Cartography, Remote Sensing, Database Technology, Geography, Geology, Hydrology, Agriculture, Resource Management, Environmental Science and Public Administration.
- (D) Box 4.1 uses the cycle-shop stock register as the example of non-spatial data, because its parts can be located anywhere.
- (B) The chapter explains this data is spatial because one of its attributes, the name of different states, has a definite location in a map.
- (D) Fig. 4.1 shows a benchmark (BM 123) as the point feature, a river as the line feature and a lake as the area feature.
- (B) The chapter names three factors: the application area itself, the available budget, and the type of data structure, i.e. vector/raster.
Assertion-Reason
- (A) Both A and R are true, and R correctly explains A: exact matching does combine two files about the same features, and it does so precisely because a common key, such as the town name, lets matching records in each file be found and joined.
Match the Following
- (D) Spatial data have a positional/linear/areal form (3); non-spatial data can be located anywhere, like a stock register (4); attribute data describe a property, e.g. road width (1); a geographic database holds attributes and their value or class (2).
Statement-Based Questions
- (C) Both statements are correct: the chapter describes non-spatial (attribute) data as data that can be located anywhere, and spatial data as characterised by positional, linear and areal forms of appearance.
Arrange in the Correct Order
- (A) The chapter gives this exact sequence of five GIS activities: spatial data input, entering the attribute data, data verification and editing, spatial and attribute data linkages, and spatial analysis.
Odd One Out
- (C) The chapter’s five named components are Hardware, Software, Data, People and Procedures. The Internet is not named as a separate component.
Passage-Based Questions
- (B) The passage states directly that a GIS is a system for capturing, storing, checking, integrating, manipulating, analysing and displaying such data.
- (C) The passage states this kind of analysis is called proximity analysis.
True / False
- (A) (i) and (ii) are correct, matching the chapter directly. (iii) is false: representing a feature as a grid of cells describes raster data, not vector data.
