1. What is the primary purpose of a Geographic Information System
(GIS)?
A. To store and edit spreadsheet data
B. To capture, store, analyze, and display spatial or geographic data
C. To replace database management systems
D. To create high-resolution raster art files
GIS integrates geographic features with attribute data to enable
spatial analysis and decision-making.
2. Which coordinate system component defines positions on the earth’s
surface using latitude and longitude?
A. State Plane Coordinate System
B. Geographic Coordinate System (GCS)
C. Universal Transverse Mercator (UTM)
D. Local tangent plane
A Geographic Coordinate System uses angular measurements
(latitude and longitude) to locate points on the globe.
,3. What is the primary difference between raster and vector data
models?
A. Raster stores relationships between points, vector stores imagery
B. Raster is always larger in file size than vector
C. Raster represents data as a grid of cells, vector uses points, lines,
and polygons
D. Raster cannot be used for analysis
Raster organizes spatial information within a grid of cells while
vector uses discrete geometric elements.
4. Which format is most appropriate for storing high-precision vector
data with attributes?
A. JPEG
B. BMP
C. Shapefile (.shp)
D. MP4
Shapefiles are widely used vector formats that store geometry and
attributes for GIS analysis.
5. What does GPS stand for in a GIS context?
A. Geographic Positioning System
B. Geo-Processing Software
C. Global Plotting Software
D. Global Positioning System
GPS uses satellites to determine precise positions on the earth’s
surface for mapping and GIS.
6. Which topology rule ensures that polygons in a dataset do not
overlap?
A. Must have gaps
B. Must not overlap
C. Must touch all
, D. Must contain nodes
The topology rule “must not overlap” prevents polygon features from
overlapping in a spatial dataset.
7. What is a geodatabase in GIS?
A. A spreadsheet with longitude values
B. A collection of raster files only
C. A database designed to store, query, and manage spatial data and
attributes
D. A 3D modeling engine
A geodatabase holds spatial and attribute data in an organized
database structure for efficient use in GIS.
8. Which analysis would you use to determine the shortest route
between multiple points?
A. Buffer analysis
B. Overlay analysis
C. Network analysis
D. Raster classification
Network analysis uses pathfinding algorithms to calculate optimal
travel routes across a network of features.
9. What is the purpose of a buffer in GIS?
A. To improve rendering speed
B. To convert raster to vector
C. To generate zones around features at a specified distance
D. To reproject data
Buffering creates areas around features to analyze proximity
relationships in GIS.
10. In GIS, what does projection refer to?
A. Printing maps
B. Transforming the 3D earth onto a 2D surface
