Topographical surveys, ground surveys or Topo Surveys are accurate surveys produced by Land Surveyors to precisely depict the topography of an area of interest or parcel of land and the structures and features upon it.

A topographical survey can be a 3d model, a 2d map or a plan showing physical features. Features could be structures, utility covers, areas of ground cover, trees or vegetation. Levels are shown with break lines to control the shape of the surface model and contours to join points of equal level.

Typically utility service covers and other service markers are identified, sometimes with underground services traced and marked with overhead services, depending on client specifications. Adjacent or overlooking features can be included to assist in assessing the setting of a site in the wider landscape, or street scene or in assessing the proximity of critical features.

Add clarity, context and understanding

For many projects, a Topographical survey can be combed with a hydrographic survey, a measured building survey, or an underground utility survey. Add flexibility, understanding and context to a topo survey. As a result, usability can be vastly improved. Our surveyors can add various kinds of spatial data to a topo survey.
