Quiz: History and Practice of Cartography — 23 questions

1. What does cartography encompass beyond the technical production of maps?

A. Measuring distances between locations with surveying instruments

B. Recording only the physical features visible from the ground

C. Classifying places according to their political boundaries

D. Using maps to establish relationships and explain geographic phenomena

Answer: (D)

Explanation

Cartography is both a discipline that creates maps and a geographic research instrument for establishing relationships and explaining phenomena. It is therefore broader than mapmaking alone.

2. What is the primary function of graphic semiology in cartography?

A. Translating information into graphic signs

B. Determining the altitude of every mapped location

C. Selecting the geographic area represented on a map

D. Calculating the curvature of Earth’s surface

Answer: (A)

Explanation

Graphic semiology consists of the rules used to translate information into graphic form, especially through signs and visual symbols. Cartography is the broader discipline that produces and uses maps.

3. Which statement correctly distinguishes a topographic map from a thematic map?

A. A topographic map shows only political boundaries, whereas a thematic map shows only elevation

B. A topographic map inventories relief and main human activities, whereas a thematic map focuses on a particular phenomenon

C. A topographic map focuses on one statistical phenomenon, whereas a thematic map inventories relief and human activities

D. A topographic map represents time zones, whereas a thematic map represents geographic coordinates

Answer: (B)

Explanation

Topographic maps provide an inventory of relief and major human activities. Thematic maps are designed to represent a specific qualitative or quantitative phenomenon.

4. How is latitude defined?

A. The distance between a point and the nearest pole

B. The angle formed by two neighboring lines of longitude

C. The angular position of a point measured relative to the equator

D. The angle between a point and the reference meridian

Answer: (C)

Explanation

Latitude is the angular position of a point relative to the equator, measured between the equatorial plane and the vertical through that point. Longitude, by contrast, is measured relative to a reference meridian.

5. What geographic division is defined by the equator?

A. It marks the poles and has latitude 90° in both hemispheres

B. It separates the tropical and polar zones and has latitude 66° 33′

C. It separates the northern hemisphere from the southern hemisphere and has latitude 0°

D. It separates the eastern hemisphere from the western hemisphere and has longitude 0°

Answer: (C)

Explanation

The equator is assigned latitude 0° and separates the northern, or boreal, hemisphere from the southern, or austral, hemisphere. The poles have latitude 90°.

6. What does longitude measure?

A. The height of a point above sea level

B. The angular distance between a point and the equator

C. The distance between the two geographic poles

D. The angle between the reference meridian and the vertical plane through a point

Answer: (D)

Explanation

Longitude is the angle between the reference meridian and the vertical plane passing through a point. Latitude instead measures angular position relative to the equator.

7. What change occurred in 1884 regarding longitude and universal time?

A. The equator became the definitive reference line, and local solar time became universal time

B. The poles became the reference points for longitude, and time zones were eliminated

C. The Greenwich meridian became the definitive reference meridian, and Greenwich Mean Time became universal time

D. The Paris meridian became the definitive reference meridian, and Greenwich Mean Time was abandoned

Answer: (C)

Explanation

In 1884, the Greenwich meridian was adopted as the definitive reference meridian for longitude, and Greenwich Mean Time became universal time.

8. Why can no flat map projection preserve distances, areas, and angles simultaneously?

A. Flat projections are designed to display political boundaries rather than measurements

B. Distances, areas, and angles are identical only at the equator

C. A flat surface cannot represent Earth’s spherical geometry without sacrificing at least one property

D. Map projections use symbols that cannot represent physical measurements

Answer: (C)

Explanation

Because Earth is spherical, flattening its surface necessarily introduces distortions. Each projection prioritizes some properties, but none preserves distances, areas, and angles all at once.

9. Which comparison between the Mercator and Peters projections is accurate?

A. Mercator preserves surfaces but distorts angles, while Peters preserves angles but distorts high-latitude surfaces

B. Both projections preserve distances but differ in how they represent elevation

C. Mercator preserves angles but distorts high-latitude surfaces, while Peters preserves surfaces but distorts distances

D. Both projections preserve angles and surfaces equally but distort only geographic location

Answer: (C)

Explanation

The Mercator projection preserves angles while considerably enlarging or distorting surfaces at high latitudes. The Peters projection preserves surfaces but distorts distances.

10. What does a contour line, or isohypse, represent?

A. Places receiving the same amount of annual rainfall

B. Points at the same altitude relative to a reference level

C. Locations connected by the same political boundary

D. Points at the same latitude relative to the equator

Answer: (B)

Explanation

A contour line joins all points at the same altitude relative to a reference level, such as sea level. It is therefore used to represent relief.

11. What is the main consequence of using a small cartographic scale such as 1/1,000,000?

A. More information must be selected and omitted than on a large-scale map

B. Every visible feature can be represented without generalization

C. Relief can be shown only through contour lines at large intervals

D. The map approaches exhaustive detail for a small geographic area

Answer: (A)

Explanation

A small scale represents a large area and therefore requires greater selection of information. A large scale such as 1/25,000 allows a more nearly exhaustive representation of details.

12. What major distinction characterized Greek and Roman cartography in antiquity?

A. Greek cartography pursued theoretical understanding, whereas Roman cartography served administration and control

B. Greek cartography produced portulans, whereas Roman cartography developed spherical models of Earth

C. Greek cartography mapped only roads, whereas Roman cartography represented the entire known world mathematically

D. Greek cartography focused on taxation, whereas Roman cartography pursued philosophical theories of nature

Answer: (A)

Explanation

Greek thinkers emphasized theoretical and natural understanding, including Earth’s shape and coordinates, while Roman cartography was primarily practical and administrative.

13. Which document would best reflect the practical administrative purposes of Roman cartography?

A. A cadastre used for land division and taxation

B. A philosophical model describing Earth as a sphere

C. A portulan showing coastal bearings and rhumb lines

D. A theological world map containing mythical monsters

Answer: (A)

Explanation

Roman cartography produced practical documents such as cadastres for dividing land and collecting taxes. The other choices represent different cartographic traditions or purposes.

14. Why is Ptolemy’s Geography considered especially important in the history of cartography?

A. It synthesized ancient cartographic knowledge and was later rediscovered through Byzantine and Arab copies

B. It provided the first precise nautical charts created by Italian sailors

C. It introduced the first Roman cadastres for taxation and land division

D. It established the five-continent division used in modern geography

Answer: (A)

Explanation

Ptolemy’s Geography brought together ancient cartographic knowledge and later returned to Western Europe through Byzantine and Arab transmission.

15. What feature most clearly distinguished the portulans developed by Italian sailors in the thirteenth century?

A. They combined satellite observations, databases, and computerized spatial analysis

B. They combined coastal descriptions, distances, ports, compass directions, and rhumb lines

C. They combined theological interpretations, mythical creatures, and biblical geography

D. They combined land-tax records, property boundaries, and administrative districts

Answer: (B)

Explanation

Thirteenth-century portulans were precise nautical charts based on coastal information, distances, ports, compass directions, and rhumb lines.

16. How did triangulation contribute to cartographic measurement under Louis XIV and Colbert?

A. It recorded distances between cities for Roman administrative travel documents

B. It converted Earth’s spherical surface directly into a flat map

C. It classified geographically referenced information in digital databases

D. It improved the precision of positions and measurements of Earth and longitude

Answer: (D)

Explanation

The French Academy of Sciences supported more precise measurement of Earth and longitude through triangulation, which improves positional accuracy rather than flattening the globe.

17. Which list represents the traditional division of inhabited emerged land into five continents?

A. Africa, Asia, Europe, Oceania, and Antarctica

B. America, Asia, Europe, Oceania, and Antarctica

C. Africa, America, Asia, Europe, and Oceania

D. Africa, America, Asia, Europe, and Antarctica

Answer: (C)

Explanation

The traditional five-continent division includes Africa, America, Asia, Europe, and Oceania. Antarctica may be included in broader geographical definitions.

18. What sequence best describes modern map production?

A. Determine satellite position, then create a Roman administrative itinerary

B. Represent selected data, then collect supporting information

C. Classify continents, then measure longitude through triangulation

D. Collect information, then represent the selected data

Answer: (D)

Explanation

Modern map production first gathers information and then represents the data selected for mapping.

19. Which method measures terrain from a distance rather than directly observing and measuring it on the ground?

A. Land-tax assessment

B. Field surveying

C. Photogrammetry

D. Compass navigation

Answer: (C)

Explanation

Photogrammetry derives measurements of terrain remotely, while field surveying involves direct observation and measurement on the ground.

20. What is the defining function of a geographic information system, or GIS?

A. It determines an object’s exact position using satellite radio signals

B. It divides land into taxable parcels without storing other geographic information

C. It organizes, classifies, selects, and processes geographically referenced information in databases

D. It produces only nautical charts from coastal descriptions and compass directions

Answer: (C)

Explanation

A GIS is a computerized system for managing and processing geographically referenced information stored in databases.

21. What determines an object’s exact position in a GNSS?

A. Triangulation between property boundaries

B. Distances recorded in city itineraries

C. Rhumb lines drawn on portulans

D. Radio signals from satellites

Answer: (D)

Explanation

A GNSS uses satellite radio signals to determine the exact position of an object on Earth’s surface.

22. Why is a map considered a model and simplification of reality rather than an identical reconstruction?

A. Its scale requires selecting information, and its form reflects production conditions, norms, and values

B. Its purpose is to eliminate interpretation by presenting only objectively measured features

C. Its accuracy depends on copying reality without reducing or reorganizing any information

D. Its symbols reproduce every feature of reality at the same size and level of detail

Answer: (A)

Explanation

A map reduces reality through scale and selection, while its design reflects the conditions, norms, and values involved in producing it. A full-scale reproduction would not provide the useful reduction characteristic of a map.

23. A dataset is divided into five classes containing approximately the same number of observations in each class. Which method of discretization is being used?

A. Standardized classification relative to the mean

B. Equal-count classification using quintiles

C. Classification based on cartographic symbol size

D. Classification by identical physical intervals

Answer: (B)

Explanation

Equal-count classes organize observations into groups of similar size; dividing the data into five such groups produces quintiles. Standardized classes instead describe values according to their relationship to the mean.
