What is the difference between angles and bearings

For these reasons, land surveyors rely on transits or their more modern equivalents, called theodolites to measure angles. A transit consists of a telescope for seeing distant target objects, two measurement wheels that work like protractors for reading horizontal and vertical angles, and bubble levels to ensure that the angles are true.

A theodolite is essentially the same instrument, except that some mechanical parts are replaced with electronics. Surveyors express angles in several ways.

Ask A Question. Contents: What is Azimuth in Surveying? What is Bearing in Surveying? There can be many types of Azimuths. They are geodetic, magnetic or astronomic. It is a rule that the reference median should be stated at the beginning of the survey. This is done to avoid mistakes in the measurement. The measurement is done by forwarding azimuth and a backward azimuth. The forward azimuth declares the forward direction, but the backward Azimuth refers to the reverse direction.

It is also used in many other areas such as control surveys, topographic surveys, and others. The angle is the measure of deviation from North or South. This is the horizontal angle measurement from a fixed point to the direction of the object. Celestial navigation uses Azimuth for all the angle measurements. Bearing refers to an acute angle. The angle is between reference meridian and given line. The measurement begins from North or South and then goes towards East or West.

The angle will always be less than degrees. The angle is represented by an alphanumeric. There are many types of bearing available. A local magnetic meridian is used to measure a magnetic bearing. Another feature is the bearing type and method syntax. Solution B: In the spirit of the Fortran "Why branch when you can math?

Each bearing will be stored in an object that inherits methods to accomplish all parts of the task: accept a new number of degrees, automatically adjusting to the range [, ]; construct new bearing objects; subtract another bearing from itself and return the difference; construct a list of new bearing objects given a list of arbitrary degree sizes; and format the number of degrees into a modest human-readable format.

Bearings will be zero-initialized by default if no degree size is provided. This program is meant to be saved in the same folder as a file angles. Each pair of angles to subtract appears on its own line in the input file.

This implementation takes two user inputs with Get-AngleDiff or prints the examples with Get-Examples. Hopefully a lot simpler, elegant and efficient by avoiding conditional statement and trigonometric functions. Some extra coding was added for a better visual presentation; the angles were centered, the answers were aligned.
