How to measure Baseline
In surveying procedures such as traversing, triangulation, trilateration, and setting out, baseline measurement is critical. Prior to the invention of the Electromagnetic Distance Measuring Instrument, baseline measurements were made with…
Magnetic Bearing
It is termed as a survey line makes angle with respect to the magnetic meridian. It changes from location to location and based on MN. It is also defined as an angle…
How To Calculate True Bearing From Magnetic Bearing
If the magnetic declination at a place at the time of observation is known, the true bearing of a line can be calculated from its magnetic bearing and vice-versa. The…
Fore Bearing and Back Bearing in Surveying
Bearings measured in the direction of progress of the survey are known as fore bearing and bearings measured opposite to the direction of the survey are known as back bearing.…
Bearing in Surveying
In this post, we are going to discuss about the bearing in surveying and its designation. The direction of a survey line can either be established with relation to each…
Errors in Chain Surveying – Types and Causes
The errors formed in chaining can be either cumulative error and compensating error. The errors can be considered either as a negative value or positive value depending on whether the result is…
Incorrect Chain in Surveying – Error & Correction
If the chain that is employed for measuring length is not equal to the true length, then the length measured won't be correct. This measurement hence requires correction. A chain…
Indirect Ranging
Indirect ranging is employed when the two points are not intervisible or the two points are at a long distance. This may be due to some kind of intervention between…
