Free GIS for Engineering (Knowledge) Questions and Answers — Questions and Answers
Question 1: GIS represents _______.
- Global Information System
- Geographic Information system (Correct answer)
- Geographic internal system
- None of the above
Correct answer: Geographic Information system
GIS stands for Geographic Information System, the standard term for the technology that captures and analyzes location-based data. The other options use incorrect words like "Global" or "internal" that are not part of the actual acronym.
Question 2: The GIS gathers and examines ______ data.
- Geographic
- Spatial
- Both Spatial and Geographic (Correct answer)
- None of the above
Correct answer: Both Spatial and Geographic
GIS works with both spatial data (the location/geometry of features) and geographic data (the attributes describing those features), so the combined answer is correct. Choosing only one type leaves out half of what GIS actually processes.
Question 3: Tools for GIS applications are ________.
- Computer (Correct answer)
- Mobile
- Machinery
- None of the above
Correct answer: Computer
The correct answer is Computer because GIS relies on computers to process, analyze, store, and display geographic information. Mobile devices and machinery are not the core tools that run GIS software and computations.
Question 4: Which of the following tasks can be carried out by a user using GIS tools?
- Create searches
- Edit data
- Store data
- All of the above (Correct answer)
Correct answer: All of the above
"All of the above" is correct because GIS lets users create searches, edit data, and store data as part of its full range of functions. Each listed option is only one capability, so naming a single one would be incomplete.
Question 5: Which of the following describes a subfield of GIS theory research?
- Geographic data
- Geographic science
- Geographic information science (Correct answer)
- None of the above
Correct answer: Geographic information science
Geographic Information Science is the academic subfield that studies the underlying theories, principles, and concepts behind GIS. "Geographic data" and "Geographic science" are not the recognized names of this research discipline.
Question 6: None of the above
- Key index
- Key
- Key index variable (Correct answer)
- None of the above
Correct answer: Key index variable
A key index variable is correct because it is a field used to uniquely identify and quickly retrieve records, improving search efficiency in a database. "Key index" or "Key" alone do not describe the full term for this type of indexing variable.
Question 7: A place in ______ dimensional coordinates is represented by a GIS.
- 3 (Correct answer)
- 2
- 5
- 4
Correct answer: 3
GIS represents a place in 3 dimensional coordinates because it accounts for not just horizontal position (X and Y) but also elevation or depth (Z). Two dimensions would only describe a flat surface, and 4 or 5 dimensions exceed what physical spatial coordinates require.
Question 8: X-coordinate is represented by GIS in the _______ direction.
- Tangentially
- Horizontal (Correct answer)
- Vertical
- None of the above
Correct answer: Horizontal
The X-coordinate is represented in the horizontal direction, following the standard Cartesian system where X runs along the east-west axis. Vertical describes the Y-axis, so it is incorrect here.
Question 9: Y-coordinate is represented by GIS in the _______ direction.
- Vertical (Correct answer)
- Horizontal
- Tangentially
- None of the above
Correct answer: Vertical
The Y-coordinate is represented in the vertical direction, matching the standard coordinate system where Y runs along the north-south axis. Horizontal refers to the X-axis, so it does not apply.
Question 10: Z-coordinate is represented by GIS in the _______ direction.
- Horizontal
- Tangentially (Correct answer)
- Vertical
- None of the above
Correct answer: Tangentially
The Z-coordinate is represented tangentially because it adds the third dimension (such as height or depth following a surface), distinct from the flat horizontal and vertical axes. Horizontal and vertical already describe the X and Y coordinates.
Question 11: Which of the following GIS metrics best captures the physical position of an object on Earth?
- Location
- Extent references
- Spatial-temporal
- All of the above (Correct answer)
Correct answer: All of the above
"All of the above" is correct because location, extent references, and spatial-temporal data all work together to precisely capture an object's physical position on Earth. Relying on just one metric would not fully pinpoint a real-world position.
GIS represents _______.
