Introduction to Physcial and Human
Geography D199
What are maps used for? - correct answer ✔- show an area larger than a
person can see
- present information concisely, especially the features of most interest to the
user
- demonstrate spatial relationships
- show things people cannot see directly, such as minerals below ground or
records of daily temperatures.
Reference map - correct answer ✔- store data and show a variety of features
for a variety of uses.
- general storehouses of information
Thematic maps - correct answer ✔- highlight specific themes
-goal is to focus the user's attention on specific features or characteristics
Literal maps - correct answer ✔- show actual things and places
Figurative map - correct answer ✔- show conceptual or imagined places
Analytical mapping - correct answer ✔- used to explore the role of location
and space to answer questions
- Dr. John Snow, cholera outbreak
Geographical Information Science (GIS) - correct answer ✔- use of
computers in mapping.
,- excels at bringing together many layers of data for a location and conducting
a sophisticated analysis.
- allow investigators to store, manipulate, and analyze data on a large variety
of phenomena.
scale - correct answer ✔- how map units relate to real-world units
Projections - correct answer ✔- the methods and challenges around turning
a three-dimensional (and sort of lumpy) earth into a two-dimensional map.
Map scale - correct answer ✔- measures how much the features of the world
are reduced to fit on a map; or more precisely, map scale shows the
proportion of a given distance on a map to the corresponding distance on the
ground in the real world.
Representative Fraction - correct answer ✔- map scale is shown as a ratio.
With the numerator always set to 1, the denominator represents how much
greater the distance is in the world.
Coordiantes - correct answer ✔- Locations on the earth's surface are
measured in
- Cartesian coordinate system, simplest system, named after René Descartes
Geographical Coordinate System - correct answer ✔- designed specifically
to define positions on Earth's roughly spherical surface
Longitude - correct answer ✔- east-west scale
- ranges from +180° to -180°.
, International Date Line - correct answer ✔- Because the earth is round,
+180° (or 180° E) and -180° (or 180° W) are the same grid line
Prime Meridian - correct answer ✔- the line of longitude that passes through
Greenwich, UK, which is the starting point for counting the rest of the lines of
longitude
- line of longitude defined as 0°
projections - correct answer ✔- turning a three-dimensional globe into a two-
dimensional map
- involves shearing, tearing, and compression
Graticule - correct answer ✔- specifies positions on the globe with latitude
and longitude coordinates.
Conformal Projection - correct answer ✔- preserve shape and angle, but
strongly distort area in the process.
- useful for navigation, topography (elevation), and weather maps
equal area projection - correct answer ✔- the size of any area on the map is
in true proportion to its size on the earth.
- countries' shapes may appear to be squished or stretched compared to what
they look like on a globe
- used for thematic data, especially in mapping density (an attribute over an
area)
- EX: it would be useful in comparing the density of Syrian refugees in the
Middle East or the amount of cropland in production.
