A Topographical Survey is a type of land survey that shows the natural and man-made features of an area together with their elevations and positions on the ground. It provides a detailed representation of the shape, size, and height of the land surface.
It includes features such as:
Hills and valleys
Rivers and drainage systems
Roads and buildings
Trees and vegetation
Boundaries and utility lines
Topographical surveys use contour lines and spot heights to indicate differences in elevation.
