Which type of survey provides information on contours, property boundaries, and existing natural features?

A topographic survey is specifically designed to provide detailed information regarding the contours of the land, property boundaries, and existing natural features such as trees, streams, and elevation changes. This type of survey captures the three-dimensional aspects of the terrain, giving architects and planners essential data for understanding site conditions and constraints that influence design decisions.

Topographic surveys often use instruments like theodolites or total stations to establish precise measurements and generate detailed maps that indicate landforms and elevations, which are crucial for any construction or landscape alteration. By assessing these elements, professionals can better address drainage, grading, and the overall integration of the built environment with the natural landscape.

Other types of surveys mentioned serve different purposes. While boundary surveys focus primarily on delineating property lines, land surveys can encompass various assessments without necessarily detailing topographical evidence, and site analysis may include broader considerations beyond just the physical features of the land.
