QUESTIONS AND VERIFIED ANSWERS ALL THE BEST
3 ways the earth's shape can be mathematically defined
sphere, ellipsoid, geoid
The only correct representation of the Earth's surface
geoid
Equivalent projection + example
allows for comparing the surfaces of the Earth within the map, since the areas of
the continents are accurate
Latitude
horizontal lines
angle that describes the north south position
Longitude
vertical lines
angle that describes the east west position
Prime Meridian
Greenwich
origin of the measures of longitude (0 degrees of longitude)
Parallel
, 2
circle connecting all locations with a given latitude
the shapes of the continents are distorted
ex. Mollweide or Gall-Peters
Conformal projection + example
the angles between positions are preserved so that ships can navigate from place
to place and know how far it is going to be from where they are
land area is distorted
ex. Mercator
Considering the case of Africa and Greenland, describe how map projections
might influence the perspective of the map viewer?
mercator projection is not an equal-area projection and distorts the relative size of
landmasses, exaggerating the poles
How was the metre first defined?
one ten-millionth the size from the length of the equator to the North Pole
How is the metre defined now?
defined as the length that light travels in a fraction of a second
The name of the unit that is equal to 1000nm
1 micrometre
Small scale map
covers a more area, but with not as much as detail
Large scale map
covers a small area but with great detail and accuracy
Two ways scale can be indicated on a map
