Study Notes
Topographic Maps
- Allow geographers to identify landscape, gradient of a slope, relief, and aspect and height above sea level using contour lines
Contour Lines
- Represent areas of equal elevation on a map
- Steepness of slopes is also represented
- Contour interval represents the difference in elevation between two adjacent contour lines
- Example: 20ft contour interval on a specific map
Local Relief
- Difference in elevation between the highest and lowest points in a region
- Calculated using the equation: Highest point - Lowest point
- Example: Local relief between points Z and X is 80ft
Gradient
- Calculated using the equation: Rise (vertical interval) / Run (horizontal distance)
- Example: Gradient between R and S is 1:25 (simplified) or 80/2000 (unsimplified)
Aspect
- Direction a slope faces
- Examples:
- Point A: Southeast
- Point B: South
- Point C: Northwest
- Point D: West
- Mount Florence (AR8746): Southeast
Map Analysis
- Contour interval: 50 metres
- Local relief between points B and H: 100ft
- Gradient of A and B: 45/100
