Local attraction in compass surveying refers to the magnetic influence exerted by nearby objects on the compass needle, causing it to deviate from true north. This can introduce errors in compass readings and must be taken into account to ensure accurate surveying measurements. Techniques such as using a baseplate compass or adjusting readings for local declination can help mitigate the effects of local attraction.

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 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.
How do you use prismatic compass?
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 do you find your mortgage survey?
To find your mortgage survey, you can request a copy from your mortgage lender or contact the surveyor who conducted the survey. You can also check with your county or local land records office as they may have a copy on file.
Datum to start survey in land survey?
The datum used to start a survey in land surveying typically refers to a known point with established coordinates. This point serves as a reference for all other measurements taken during the survey. It is essential for ensuring accurate positioning and alignment of survey data within a specific coordinate system.

What are the advantages and disadvantages of gyro compass?
The disadvantages of using a compass for surveying is that readings are often inaccurate (accuracy dependent on size and graduations of compass, it is easily disturbed by effects of local magnetic attraction

How can you find out the locations and opening hours of your local Compass Bank?
You can visit you local Compass Bank and search for opening hours or ask a employer. Furthermore you can visit the official Compass bank website and look for your local bank.
How local attraction be corrected?

Does a compass remain stable or it fluctuate?
A compass is stable in it's attraction to a specific magnetic pole. Any instability detected is the fluctuation of the always moving magnetic field. Or probably more typically has been induced by vibration of the compass
Where can one find sample survey?
One can find sample survey questions at your local survey questonaire (refer to your local town office to find more details). One could also look through the Survey Center website to find sample surveys to take.
