It deals with distance and angle measurement - levelling and trigonometric levelling, traversing and triangulation survey, total station, horizontal and vertical curves. It is a continuation of my previous course named Surveying - Part 1.

A prismatic compass is a navigation and surveying instrument which is extensively used to find out the bearing of the traversing and included angles between them, waypoints (an endpoint of the course) and direction. Compass surveying is a type of surveying in which the directions of surveying lines are determined with a magnetic compass, and the length of the surveying lines are measured with a tape or chain. The compass is generally used to run a traverse line. The compass calculates bearings of lines with respect to Magnetic North. The included angles can then be calculated using suitable formulas in case of clockwise and anti-clockwise traverse respectively. For each survey line in the traverse, surveyors take two bearings that are fore bearing and back bearing which should exactly differ by 180° if the local attraction is negligible. The name Prismatic compass is given to it because it essentially consists of a prism which is used for taking observations more accurately.

The course Theory of Errors is divided into two parts. Part 1 of the course will provide knowledge about errors, its types, how to measure errors and what are the different methods to quantify errors, very concisely and precisely. Each concept related to the theory of errors are thoroughly discussed in this course. Examples are also solved to give a better understanding of important concepts.

(Hindi) Part 1: Theory of Errors

Accuracy and Precision
-Accuracy and precision are two different, yet equally important surveying concepts. 
Accuracy is the degree of conformity of a given measurement with a standard value. 
Precision is the extent to which a given set of measurements agree with their mean.
Measurements are never exact and there will always be a degree of variance regardless of the survey instrument or method used. These variances are known as errors and will need to be reduced or eliminated to maintain specific survey standards.
Even when carefully following established surveying procedures, observations may still contain errors. Errors, by definition, are the difference between a measured value and its true value. The true value of a measurement is determined by taking the mean value of a series of repeated 
measurements. Surveyors must possess skill in instrument operation and knowledge of surveying methods to minimize the amount of error in each measurement.
