2.2. Accuracy, Errors, and Applications

Accuracy, Errors, and Applications

This sub-chapter explains how to ensure reliability and apply measurements in practice.

• Sources of Error
• Instrumental, natural, and human errors.
• Correction methods: repeat measurements, calibration, cross-checking.
• Accuracy vs. Precision
• Accuracy = closeness to true value.
• Precision = consistency of repeated measurements.
• Real-World Applications

• Construction: Aligning roads and buildings.
• Agriculture: Ensuring proper drainage.
• Urban planning: Safe and efficient layouts.

✅ Key Takeaways

• Surveying relies on distance, angle, and elevation.
• Errors are inevitable but manageable.
• Accuracy and precision together ensure reliable results.
• Applications span construction, agriculture, and urban planning.
