Overview
This lecture covers the main compass directions, in-between directions, how to remember them, and introduces the concept of three-figure compass bearings.
Compass Directions
- The four main compass directions are North, East, South, and West, ordered clockwise.
- "Never Eat Soggy Waffles" helps remember the order: North, East, South, West (NESW).
- "WE" can also help, since West and East are side by side when North is ahead.
In-Between Directions
- Between main directions are North-East (NE), South-East (SE), South-West (SW), and North-West (NW).
- Further divisions include NNE, ENE, ESE, SSE, SSW, WSW, WNW, and NNW for even more precise directions.
- These in-between directions help describe more exact bearings, such as NNE (north-north-east) or SSW (south-south-west).
Three-Figure Bearings
- Three-figure bearings provide precise direction using a three-digit number measured clockwise from North.
- North is 000, East is 090, South is 180, and West is 270.
- Bearings are measured with leading zeros if needed (e.g., 045 for NE).
- These bearings are used in navigation by pilots and sailors for accuracy.
- Any direction can be described uniquely, such as 225 for South-West.
- Decimals may be used for even more precision (e.g., 022.4).
Key Terms & Definitions
- Compass Rose — a diagram showing directions on a compass.
- Compass Bearing — the direction from a specific point, often stated as N, NE, S, etc.
- Three-Figure Bearing — a direction given as a three-digit number measured clockwise from North (000° to 360°).
Action Items / Next Steps
- Practice identifying directions and bearings using a compass rose.
- Memorize the main and in-between compass directions.
- Try converting compass directions to three-figure bearings.
