S2 3.1 tape and offset surveying. importance of the features. Topographic surveying is the process of determining the positions, both is plan and elevation of the natural and artificial feature of a region and delineating them by means of conventional symbols upon a map called topographic map. Compass Surveying : Horizontal angles are measured with the help of a magnetic compass. The size of a field survey party depends upon the survey requirements, the equipment available, the method of survey, and the number of personnel needed for performing the different functions.
