Study Notes
Map Projections Overview
-
Mercator Projection
- Useful for navigation due to its accurate directional representation.
- Distorts area, making polar landmasses appear oversized.
-
Gall-Peters Projection
- Created to accurately represent the relative sizes of continents (equal area).
- Distorts shape, lacking conformality.
-
Robinson Projection
- Balances overall shapes and relative positions, minimizing distortion.
- Does not preserve complete accuracy in area, shape, distance, or direction.
-
Dymaxion Projection
- Developed by Buckminster Fuller, challenging traditional directional conventions (N, S, E, W).
- Preserves shape and size of land but distorts distance and direction.
-
Winkel-Tripel Projection
- Modified azimuthal projection with a balance of size, shape, distance, and direction.
- Preferred map projection by National Geographic.
-
Goode's Homolosine Projection
- Known as the "orange peel" map, it is an equal-area composite projection for world maps.
- Features multiple interruptions, showing true size and shape of landmasses.
-
Waterman Butterfly Projection
- A complex 14-sided polyhedral projection that addresses distortion and partitioning of land masses.
-
Sinusoidal Projection
- Characterized by a smooth curve that accurately reflects the center, though distortion increases towards the edges.
-
Miller Cylindrical Projection
- A modified version of the Mercator projection.
- Minimizes relative size distortion but maintains accurate direction only at the equator.
-
Mollweide Projection
- Describes the Earth's surface as an ellipse, with equator and parallels as straight lines.
- Represents area well but distorts shape and direction.
-
Azimuthal (Polar) Projection
- Displays true compass directions with straight longitude lines and circular latitude lines.
- Experiences significant shape and size distortion towards the outer edges.
