CONTOUR SURVEYING
โ€ข Contour surveying, also known as
topographic surveying, is a method used
to determine the shape, elevation, and
relief of the land's surface. It involves
mapping the contours, which are
imaginary lines connecting points of
equal elevation, on a site or an area of
interest. Contour surveys provide
valuable information for various
purposes, including land development,
engineering design, and environmental
planning.
