Because the true bearing does not measure the Earth's magnetic field exactly, scientists and researchers across disciplines compare the true bearing to the Earth's magnetic north pole to determine how it differs and study the magnetic anomalies that result from it. After studying physics and philosophy as an undergraduate at Indiana University-Bloomington, he worked as a scientist at the National Institutes of Health for two years. @afp I agree, that's def an error but an easy fix. To convert angle of bearing to degrees of a standard angle, subtract the bearing angle from 90. Most scientific calculators have conversion capabilities between the two formats. degrees = Val (Left (Degree_Deg, InStr (1 . With cad you can easily measure what the angle is between two lines. When converting to decimal don't bother about With your equipment you would have to set up directly over one pin, sight the other and turn the angle to the missing pin. We read this as 180 plus the additional 50 degrees. So, the final result is: 39 25' 30" = 39.425. Making statements based on opinion; back them up with references or personal experience. The calculator gives name of compass point by direction angle in degrees. The reason it didn't make sense because because I wasn't converting the answers back to degrees. As the documentation says: "The emphasis is on returning accurate results with errors close to round-off (about 515 nanometers).". Bearings have application in a myriad of fields from compass bearings, (the bearing a compass dictates) magnetic bearings (the bearing with respect to the north direction of the Earth's magnetic field), and true bearing (the bearing with respect to the Earth's north axis). Due to tectonic plate movement, a geographic point's lat/lon position may change by several millimeters (at least), every year. sheet. And we now have our factor for conversion from radians to degrees since 1 * 57.29578 = 57.29578. Its often necessary (although not always depending on the calculator) to convert from DMS to decimal degrees in order to perform a mathematical function on a calculator such as adding or subtracting, multiply or dividing angles, trigonometric functions, etc. used to measure bearings on a compass or a map begin with 0 degrees assigned to 1. initial.
