1.useful in areas which are difficult to be accesed while chain survey is limited 2.less subjective to errors,in comparison to chain survey which subjected with errors such as change in chain length 3.useful in surveying a large area since it uses transverse(taking bearing from observer to an object ana vice versa is true) 4.it is accurate method for mapping,compare to chain survey

The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.

A circle is the set of all points in a plane that are a given distance (or a fixed distance) from another point. Take a plane, and then pick any point on it. Then pick a distance from that point you picked and connect all the points that are that distance from your fixed point. That will describe the circumference of a circle. Another idea is to take a plane, pick any point, and then take a compass and put the point of that instrument on that point you picked. Then set a distance on the compass and draw a circle. That circle will be that set of all points a fixed distance from the original point you picked. (A string will work as well as a compass if that string is not stretched to draw the circle.)
in plane survey the surface of earth assume as plane or straight its uses as limited distance where as in geodetic survey surface of earth assume as curve its use in long distance.
A geometric compass is an instrument, or a tool, used in plane geometry to draw arcs and circles. Not to be confused with the geometric and military compass invented by Galileo.
Plain surveying means the survey in which earth surface is considered as to be flat or plain i.e. its curvature is ignored. Geodetic survey is the survey in which curvature of the earth is taken into count and then surveying is done.

Yes, it is generally permissible to bring a compass on a plane in your carry-on luggage. However, it's always a good idea to check with the airline or relevant authorities for any specific restrictions or guidelines.

Allows for mapping without the need for specialized instruments. Can be used to quickly establish control points for larger surveys. Provides a visual representation of the surveyed area for easy interpretation by surveyors.
