Map Projections

Map Projections
- What is it?
- Properties That Get Distorted
  - shape - (conformal projection)
  - area - (equal area projection)
  - distance (equi-distant projection)
  - direction (azimuthal)
- Developable Surface
  - what is it?
  - shapes
    - plane (azmuthal)
    - cylinder
    - cone
- Light -Source Location
  - gnomonic (centre)
  - stereographic (opposite)
  - orthographic (infinity)
- Orientation
  - normal
    - cylinder - equator
    - cone - parallel (latitude)
    - plane - polar
  - transverse
  - oblique
- Tangent/Secant
  - cylinder
  - cone
- Standard Lines & Distortion
  - Zones of accuracy
  - true, increased and reduced scale
- Map Projection (video)
  - Mercator (direction maintained)
    - Greenland vs Africa
  - BC - Albers (area maintained)
  - UTM (shape & direction maintained)
- UTM (in detail)
  - Zones (size & number)
  - Coordinate System
