📐 LEVEL vs COORDINATE vs BEARING vs ANGLE

🏗️ 1. LEVEL (ELEVATION)

Defines the height of a point relative to a reference datum.

📌 Example: RL = 125.350 m

📍 2. COORDINATES

Identify a point’s position using Easting (E) and Northing (N).

📌 Example: E = 500.250 m, N = 1250.750 m

🧭 3. BEARING

Indicates the direction of a survey line relative to North.

📌 Example: 045°30′

📏 4. ANGLE

Measures the difference in direction between two lines.

📌 Example: 73°15′

✅ Remember:

• Level = Height
• Coordinates = Position
• Bearing = Direction
• Angle = Difference in direction

💡 These four concepts are essential for accurate surveying and construction setting out.
