5 ESSENTIAL ELEMENTS FOR LEVELING SURVEY IN BANGLADESH

The reciprocal levelling eradicates the error on account of curvature and collimation. In addition, it gets rid of the error mainly because of the line of collimation.It can help to determine the location of a hard and fast point on the ground, by determining its elevation and by location in a identified elevation.There might be problems of vario

In barometric leveling, variances in peak are based on measuring the variations in atmospheric pressure at different elevations. Air force is calculated by mercurial or aneroid barometer, or simply a boiling stage thermometer.· Degree surface area Any surface area parallel on the indicate spheroidal surface area on the earth is said to be a level
