Question

2. To what accuracy we can find the elevations of different points​?

Answer 1

Explanation:

In Chapters 5 and 6, you learned about various devices for measuring height differences. You also learned how to use these devices to solve three types of problems in measuring height differences, which you may face when you plan and develop a fish-farm (see Section 5.0). Now, you will learn how to plan surveys to solve these problems, how to record the measurements you make in your field-book, and how to find the information you need from these measurements.

Answer 2

Accuracy that you can find the elevations of different points:

• Accuracy of baselines gained from the GPS observations.
• Accuracy of the geoid model used in the conversion to orthometric heights.
• Accuracy of the height antenna measurement above the observation points.
• The number, accuracy and geometric location of vertical control points in the network.
