Contour and Feature Surveys

A contour survey, also known as a topographic survey, is a type of land survey that maps the elevation, shape, and features of a piece of land. It involves measuring and mapping the contours of the land, which are imaginary lines connecting points of the same elevation. These contours form a detailed representation of the land’s surface, showing changes in elevation, slopes, depressions, and natural features like hills, valleys, and streams.

A feature survey, on the other hand, focuses on identifying and mapping specific physical features and characteristics of a property or area. It includes the precise location and details of man-made features such as buildings, roads, fences, utilities, trees, and other structures. Feature surveys provide comprehensive information about the existing elements on a property or site, aiding in design, planning, construction, and land development projects.

In summary, a contour survey concentrates on the natural landscape and elevation changes, while a feature survey documents and maps the various man-made and natural features present on a property or site. Both surveys are essential in various industries such as architecture, engineering, construction, land development, and environmental planning to understand the terrain and features of a specific area.
