What is prismatic compass survey
Wiki User
∙ 8y ago
To use a prismatic compass, first ensure it is set up correctly by adjusting the azimuth ring to align with magnetic north. Then, hold the compass level and sight your target through the prism while reading the azimuth on the compass dial. Ensure you compensate for any declination angle if needed.

How local attraction affect the use of prismatic compass survey?
Local attractions such as buildings or metal objects can affect the accuracy of a prismatic compass survey by causing magnetic interference. This interference can lead to errors in compass readings and, consequently, inaccurate survey measurements. To minimize these effects, surveyors should identify and account for local attractions during their surveys, employing techniques such as taking multiple readings and using a declination correction.
What is local attraction on compass survey?
The local attraction are the error affecting device available at near by the compass while doing surveying. the local attraction is the effect of the magnetic materials on the compass and gets the incorrect bearing.
What are the aims and objectives of compass survey?
The aims of a compass survey are to determine the magnetic bearing of a line and to set out accurate directions on the field. Its objectives include establishing a reference direction, determining the magnetic declination, and providing a basis for orienting maps and conducting navigation activities.
What is compass error?
Compass error refers to the difference between the actual magnetic heading of a compass and the heading it indicates. It can be caused by various factors such as magnetic interference from the ship or aircraft it is installed on, deviation due to metal objects nearby, or variation caused by the difference between true north and magnetic north. Compass error needs to be regularly assessed and corrected to ensure accurate navigation.
What are the sources of errors in compass survey?
Sources of errors in compass surveys include magnetic declination errors, local magnetic disturbances, poor compass calibration, incorrect reading of the compass, and human error in taking and recording measurements.
