3.1. Scale
Scale displays the relationship Between a distance on a map and the physical distance
- Expressed as a ratio \(1cm:50km\)
- Can also be expressed as a linear scale
3.2. Compass Rose
- The compass rose shows the four cardinal directions(North, East, South, West) on the map. The north point is always facing upwards.
3.3. Map Distortion
- To translate the globe onto something flat, we use something called projection
- This leads to misrepresentations of shape, area, distance, or directions
- various map projections exist to minimize specific distortions
- Every single form of projection have their own trade offs
(see:It is impossible to represent a sphere as a flat plane without some form of distortion)
3.3.1. Mercator
The standard map projection. Accurately displays shape and direction, but fails to represent size properly
3.3.2. Gall-Peter map projection
- Also known as the equal area projection
- Are is represented equally
- However, shape is distorted
