This set of Surveying Multiple Choice Questions & Answers (MCQs) focuses on “Components of a GIS”.
1. GIS uses the information from which of the following sources?
a) Non- spatial information system
b) Spatial information system
c) Global information system
d) Position information system
Explanation: Among the various information sources available, GIS chose spatial information system as its source for obtaining the required information for developmental process. This spatial information system serves as a base for different type of works done by the use of GIS.
2. Among the following ____________ can be expressed as an example of hardware component.
b) Arc GIS
c) Auto CAD
Explanation: GIS comprises certain key components such as hardware, software, data and user. Hardware consists of the components used in the computer which include a keyboard, monitor, CD-ROM etc.
3. Which of the following formats can be used for GIS output?
Explanation: GIS output can be handled with a wide range of formats available. Among them, the most commonly used are GIF, JPEG, TIFF etc., usage of the format depends upon the software used in computer and also its bit performing capacity.
4. In the process of GIS, digitalization is done for better output.
Explanation: Digitalization involves the conversion of the data from raster to vector so that the hardware data can be obtained in software. It can be done either by manual interpretation or by digital scanning.
5. Which among the following is not related to GIS software’s?
b) Arc GIS
c) Arc View
d) STAAD Pro
Explanation: GIS involves a different procedure which consists of several steps. So it requires a high end processing system and a software, which must adapt to its capability. Among them, STAAD Pro is not used in case of GIS. It is permitted to only structures and its analysis.
6. Among the following, which do not come under the components of GIS?
Explanation: GIS consists of certain components which denote the entire process of the system. It comprises hardware, software, user and data. These are having certain features which are accomplished at their stage.
7. Data can be shared in the process of GIS.
Explanation: The entire functioning of GIS involves developing a map or detailed analysis of the area taken for development. In this, data can be analyzed but can’t be shared. This is one of the major drawbacks in GIS procedure.
8. Which of the following doesn’t determine the capability of GIS?
a) Defining a map
b) Representing cartographic feature
c) Retrieving data
d) Transferring data
Explanation: Capability of GIS determines its ability to accomplish the work assigned. It can define a map with database, can represent cartographic feature, can store and retrieve data and many more. By doing these, it can act as a source for development of errors.
9. Which of the following acts a benefit of GIS?
a) Maintaining geo spatial data
b) Data sharing
c) Accurate data information
d) Presence of data retrieval service
Explanation: There are a lot of advantages regarding the usage of GIS. They include maintaining geo spatial data, value added products, productivity and efficiency of data, can save time and money etc.
10. Which among the following is a server based hardware platform of GIS?
a) Autodesk Revit
b) STAAD Pro
c) Arc GIS
Explanation: GIS is a place based information derivative platform, which can have a spatial feature not related to location. There are certain platforms which can have the ability to access the GIS interface. Here, Google Maps is a server based platform and remaining are offline applications.
