1. What is the primary purpose of a Geographic Information System
(GIS)?
A. To store financial records
B. To capture, store, analyze, and display spatial data
C. To encrypt communication networks
D. To manage human resources data
Answer: B
Rationale: GIS is designed to work with spatial or geographic
data, enabling analysis and visualization of location-based
information.
2. Which data type is most commonly used to represent discrete
features like roads or buildings in GIS?
A. Raster data
B. Vector data
C. Binary data
D. Tabular data
Answer: B
Rationale: Vector data uses points, lines, and polygons to
represent discrete geographic features.
3. Which GIS component defines the spatial reference of a dataset?
A. Attribute table
B. Metadata
, C. Coordinate system
D. Symbology
Answer: C
Rationale: A coordinate system defines how spatial data is
projected and located on Earth.
4. What does a raster dataset consist of?
A. Points and polygons
B. Continuous grid cells or pixels
C. Only vector lines
D. Attribute tables only
Answer: B
Rationale: Raster data represents geographic space as a grid of
cells, each with a value.
5. Which tool is used to combine multiple spatial layers into one
dataset based on location?
A. Buffer
B. Overlay
C. Clip
D. Dissolve
Answer: B
Rationale: Overlay analysis combines layers to analyze spatial
relationships.
6. What is a buffer in GIS?
A. A data encryption method
B. A zone around a feature at a specified distance
C. A type of raster conversion
D. A database index
Answer: B
, Rationale: Buffers create areas at a defined distance around
spatial features.
7. Which file format is commonly used for storing vector GIS data?
A. .jpg
B. .shp
C. .mp3
D. .txt
Answer: B
Rationale: Shapefiles (.shp) are widely used for storing vector
GIS data.
8. What is georeferencing?
A. Compressing GIS files
B. Assigning spatial coordinates to data
C. Encrypting map layers
D. Removing spatial errors
Answer: B
Rationale: Georeferencing aligns spatial data to real-world
coordinates.
9. Which spatial analysis method identifies features within a certain
distance of another feature?
A. Interpolation
B. Buffer analysis
C. Classification
D. Rasterization
Answer: B
Rationale: Buffer analysis identifies areas within a specified
distance.
10. What is the function of metadata in GIS?
A. To visualize maps
