Topographical Surveys

A Topographical Survey (sometimes referred to as a Land Survey) is the process to produce an accurate and detailed map of the features both man-made and natural within an area. The collected data may be presented in many formats from a simple paper plan to a full Three Dimensional (3D) digital model depending on the client’s requirements. Today the most common presentation is as a digital data set which is also plotted out as drawings.

The existing detail of an area may be required for either record or planning purposes. From a survey other information such as areas and volumes may be calculated. Purposes to which a Topographical Survey may be used include:

  • Housing estate or commercial redevelopment design layout
  • Highway or Railway design
  • Location of neighboring property details and boundaries for Rights of light or party wall issues
  • Cadastral Survey
  • Sale or acquisition of land
  • Locating specific items of detail
  • Showing the existing layout of surface features and services. (Underground services are in a separate guide)
  • Development or alterations to land use.
  • Location of trees and tree canopies on or off the site
  • Modelling and visualization of the ground in 3D
  • Historical records

Site mapping will produce a accurate model of the site for us to use in ACAD in which we can place our GPR scans on to. This will make a final map of the area  that has all the utilities on it that were once hidden underground.
