1.3.7 The Map Case — section quiz

Unit 1 · Introduction to Geography · Lesson 1.3 The Map Case

The big idea This is the Map Case quiz, not a separate 'Mapmakers quiz.' Apex names it 1.3.7. It covers the whole lesson: what a map is, lat/long, who made maps, why 16th-century sailors could measure latitude but not longitude, bias and validity, and GIS. If you can do the drills below, you are ready.
Ready to check a map

By the end you can

  • Use the 1.3.0 key terms: cartography, latitude, longitude, bias, validity, Landsat, and the special lines.
  • Tell map types and projections apart, and plot a lat/long point.
  • Match the big 1.3.3–1.3.6 ideas: humans still make maps, longitude needed a clock, bias is a lean, GIS stacks facts that have a location.

Before you start: this quiz is the whole Map Case

Today's planner also says The Mapmakers. That is the reading. The quiz is 1.3.7 The Map Case. Open this if you were about to study only the 16th-century essay.

What this quiz is

Canvas name: Quiz: The Map Case (1.3.7), 30 points. On the family planner it sits today with Cartographer's Studio, The Mapmakers reading, and GIS. 'Mapmakers' is the reading (1.3.4). This quiz is the whole map section.

What this quiz is (2)

Lesson 1.3.0 said you would: describe the history of cartography, identify types and purposes of maps, and find locations on maps. That is the spine.

What this quiz is (3)

Use the other hub pages for deep review. This page is the mixed drill.

Likely on the quiz Do not skip GIS and bias because you spent today on the reading. The quiz is the section, not one activity.

Pictures of the world and the grid

A map is a picture that leaves most things out on purpose. Four projection families: planar (one hemisphere / pole), cylindrical (whole world, poles stretch), conical (mid-latitudes), compromise (a little of everything, Robinson oval).

Pictures of the world and the grid (2)

Latitude first (north/south of the equator), then longitude (east/west of Greenwich). Course check from 1.3.1: 30° N, 90° W is New Orleans. Special lines: tropics about 23.5°, polar circles about 66.5°. Cancer and Arctic are north. Capricorn and Antarctic are south.

Likely on the quiz Greenland looking as big as Africa = cylindrical / Mercator stretch, not 'Greenland really is that big.'

People, then a 16th-century problem

Humans still make maps. Leaps in the 15th–16th centuries and the 20th century. Match dates if asked: Mercator 1569, Robinson 1963, Columbus 1492, Piri Reis 1513, Ptolemy 150.

People, then a 16th-century problem (2)

The Mapmakers essay is a secondary source about the 1500s. Accuracy depends on instruments, knowledge of Earth and sky, number of observations, math, and skill. They agreed to lat/long in the 16th century. Latitude they could measure (sun or Polaris). Longitude needed a clock (Harrison 1773). Workaround: dead reckoning and parallel sailing, trusting the cross-staff.

Likely on the quiz Do not put 1773 as the century they agreed to use lat/long. That is when longitude got a clock. The agreement is 16th century.

Bias, then GIS

Bias is a lean, not always a crime. Maps cannot include everything. Validity = does it do the job it was made for. A world map that is bad at finding a street is not invalid as a world map. The 1929 Surrealist map is valid as a view, not as a size chart. Never trust a single map on something important.

Bias, then GIS (2)

GIS: high-tech, computers, spatially organized information. Landsat = NASA remote-sensing satellites. Four data sources (cameras, Landsat, bar codes, environmental instruments). EMS spider diagram. GIS is not the same letters as GPS.

Likely on the quiz Bias vs validity is the pair people mix up. A biased map can still be valid. GIS vs GPS is the other pair.
