The theme of this video will be the application of magnetic surveying instruments on original and retracement surveys. These instruments include the compass, survey compass, telescope compass, transit and other special use instruments such as the solar compass and solar transit. Special emphasis will be placed on using magnetic declination and the methods used to correct magnetic to True North. Different methods will be explained on the conversion of magnetic bearings to true bearings on retracement surveys using NOAA's on line conversion table for any year from 1650 to present. Applying the corrected survey bearing to an old retracement survey will allow you to analyze the information for correctness and accuracy. Presented will be information on how the early history of magnetic attraction was discovered and became the compass used in astronomy, navigation, artillery, mapping and compass surveying, and the important role it played in the development of civilization. Current research by NGSinto gravity and declination and the role it plays in modern GPSadjustments. Pictures of many original instruments will be included in the Video presentation.
