Typically, a developer or designer will ask for a topographic survey of a parcel of land to show what features, natural or man-made are present. Most topographic surveys generally provide the vertical datum to Australian Height Datum (AHD) and the horizontal datum to either local (site) or state grid such as Map Grid of Australia (MGA).
Topographic survey plans will show details such as reduced levels (RL’s), contours, boundaries, easements, site areas, vegetation features, buildings, utilities (pits, valves, lids, vents etc.) and any other visible improvements on the land. Typically, discussions between the client and surveyor will exactly define the scope and amount of detail required to complete the survey.
DS&P can deliver the survey information in a variety of formats including 2D or 3D AutoCAD (.dwg), PDF, 12d, point cloud data (.rcp, pts, las, e57 formats).
