Reading Terrain with Topographic Maps

Topographic surveying records the shape of land by measuring elevation, slope, and natural and man-made features. Surveyors use these measurements to build a topographic map, which shows the terrain in a visual way. These maps are important for construction planning, water resource management, and land-use analysis.

Topographic surveying maps the Earth's surface, capturing elevations, slopes, and natural or man-made features. 

It is critical for construction planning, water management, and land-use analysis. The main output is a topographic map representing the terrain using contour lines.
