Study Notes
Four Types of Map Distortion
- Shape distortion alters the outline of areas; for example, the Goode projection cuts through Antarctica.
- Distance distortion may either stretch or compress the space between points; the Lambert projection demonstrates this towards the equator.
- Size distortion changes the perceived area of landmasses; the Mercator projection inaccurately represents land sizes.
- Direction distortion affects how the route between points appears; the Robinson projection exemplifies this issue.
Projection
- A projection is a scientific technique for converting locations on Earth's surface into a flat map format.
Fuller (Dymaxion) Projection
- This projection preserves the shapes of landmasses while significantly distorting bodies of water.
Peters Projection
- The Peters projection critiques the Mercator projection for exaggerating the size of landmasses, making countries appear larger than they actually are; for example, it significantly enlarges Greenland and Antarctica.
Azimuthal Projections
- Azimuthal projections display only one hemisphere at a time; the Lambert projection is a notable example.
Mollweide Projection
- The Mollweide projection is an equal-area map projection characterized by its elliptical shape.
Latitude
- Lines of latitude, known as parallels, start at 0 degrees at the equator and range from 0 to 90 degrees towards the poles.
- Latitude is often associated with a flat measurement running north to south.
Longitude
- Lines of longitude, termed meridians, extend from pole to pole and measure distances east to west of the Prime Meridian.
- The Prime Meridian is located in Greenwich, England, at 0 degrees and extends to 79 degrees west.
- Longitude lines are widest at the equator and converge at the poles.
