Topographic surveys focus on creating detailed representations of the shape and features of the Earth's surface. Ensuing topographic maps represent detailed relief features, typically using contour lines. These maps typically depict the elevation, contours, and other physical features of a particular area.
Topographic maps are used for a variety of purposes, including land use planning, natural resource management, environmental monitoring, and infrastructure design. They are particularly useful for understanding the shape and features of the land, and can help to identify potential hazards and other features that may affect the use or development of the land.
