Spatial Analysis Exam 1 Comprehensive Final
Review 2026 | 100% Accurate Answers
1. What does DRG stand for in the context of cartography?
Digital Raster Graphics
Digital Raster Geometries
Dynamic Raster Graphics
Digital Reference Grid
2. What is a disadvantage of a raster image?
They have a large file size because information has to be stored
about every pixel
They are not as colourful
They don't look as realistic as vector graphics.
3. What is the relationship between map error and map scale?
Map error increases as the scale of the map decreases.
Map error is only relevant in digital maps.
Map error is unaffected by the scale of the map.
Map error decreases as the scale of the map decreases.
4. Which of the following statements regarding topography is true?
It refers to the undulating form of earth's surface.
It means the same thing as relief.
It has had little effect on human history.
, It cannot be effectively displayed on a map.
5. Describe the primary purpose of Geographic Information Systems (GIS).
The primary purpose of GIS is to capture, store, analyze, and
manage spatial and geographic data.
The primary purpose of GIS is to enhance visual aesthetics of maps.
The primary purpose of GIS is to develop software for data entry.
The primary purpose of GIS is to create physical maps for navigation.
6. If you were tasked with designing a thematic map showing population
density, which components would you prioritize to ensure clarity and
effectiveness?
You would prioritize a clear legend, appropriate color gradients,
and a scale to represent the data accurately.
You would only need a title and a north arrow.
You would focus solely on the map's aesthetic appeal.
You would include only the population data without any additional
components.
7. Map scale is large when:
It shows a smaller section of the Earth with more detail
The representative fraction is small
The straight line distance between any 2 places can be determined
visually
The map shows the entire Earth at once
The representative fraction has a large denominator
,8. What is the definition of map scale in cartography?
The total area covered by the map.
The color scheme applied to the map.
The type of projection used in the map.
The ratio of distance on the map to the corresponding distance on
the ground.
9. What type of data does Digital Line Graph (DLG) represent in cartography?
Raster data
Spatial data
Vector data
Attribute data
10. What is the primary characteristic of Digital Orthophoto Quarter
Quadrangles (DOQQs)?
They are vector data representations of spatial features.
They are raster images without any corrections.
They are topographic maps showing elevation.
They are aerial photographs that have been geometrically
corrected.
11. In a GIS project analyzing urban development, how would you utilize
nominal, ordinal, and interval/ratio data types to assess land use?
By only using nominal data to categorize land types.
By using nominal data to categorize land types, ordinal data to rank
land value, and interval/ratio data to measure area size.
, By using ordinal data exclusively to rank land value.
By measuring distances without considering land types.
12. Describe the primary differences between point and line vector models in
terms of their representation of spatial data.
Point models are more complex than line models.
Point models represent areas, while line models represent points.
Point models represent discrete locations, while line models
represent linear features.
Point models are used for raster data, while line models are for vector
data.
13. Describe how points in spatial data models differ from other geometric
representations.
Points and lines are both represented as polygons in spatial data
models.
Points are represented as raster images, while polygons are
represented as vectors.
Points are represented as pixels, while lines are represented as
coordinates.
Points are represented as specific coordinates, while lines and
polygons are made up of multiple points.
14. Describe how Digital Orthophoto Quarter Quadrangles (DOQQs) differ
from traditional aerial photographs.
DOQQs are only used for artistic representations of landscapes.
DOQQs do not provide any spatial accuracy.
