Focusing on elevation and land features, topographical surveys, also known as feature contour surveys, are performed to assist in land development and analysis. Most typically they are utilised in the design of new subdivisions, drainage studies, council development applications and a multitude of other civil-related projects.
Analysing the variation in elevation can give a clear understanding of the land and its possibility for development as well as informing plans. Typically, a developer or designer will require a topographical survey of a parcel of land to show what natural and man-made land contours exist, including height, depth, size and location.
Topographical Surveys provide a level of rich, accurate detail that other methods are unable to achieve via through 2D or 3D representation.
Plans obtained from topographical surveys show details such as reduced levels, contours, boundaries, easements, site areas, vegetation, buildings, utilities and any other visible improvements on the land.
