Topography explained

Topography literally relates to the shape and features of land surfaces, so a topographical survey is an accurate depiction of the ground surface and its features such as

  • Buildings
  • Concrete areas
  • Significant trees
  • Areas of vegetation
  • Utility services, etc.

To depict the ground surface, spot heights are surveyed over the property that are rendered into a tin model (series of triangles) from which contours are derived.

Importance of a Topographical Survey

Your Architect and Engineer will most likely require a topographical survey to facilitate their designs and Planners use them to determine compliance with Council’s development standards.

A PDF plan is typically produced and the 3D electronic data is used to calculate earthwork volumes and design structures, dwellings, driveways, drainage, etc.
