About this document
Understanding Magnetic Declination in Surveying by Mi Mi is a document available to read on EtoBox.
This document discusses topics related to angular measurements, magnetic declination, and common mistakes made when using bearings. It defines magnetic declination as the horizontal angle between the geodetic and magnetic meridians. Declinations can be west or east. The relationship between geodetic azimuth and magnetic azimuth is provided. Variations in declination over time including secular, daily, annual, and irregular variations are described. Two sample problems demonstrate how to calculate geodetic b
