Master the least-squares method for reliable geodetic observations. This updated guide shows how to adjust data, test accuracy, and choose the best observation methods.
This edition reflects years of practical experience in the Survey and includes new material contributed by leading computing experts. It expands on how to apply the method of least squares to direct and indirect observations, and how to form and solve the necessary equations. Readers gain a clear road map for testing precision, handling different weights, and balancing measurements in complex networks.
- Understand the foundations of error theory and the least-squares principle
- Learn how to form normal equations and apply different solution methods
- Explore practical examples from triangulation, base-line measurement, and leveling
- Grasp how to assess precision, probable error, and the effect of weighting
Ideal for engineers, surveyors, and students who want a rigorous, hands-on approach to geodetic data adjustment.
