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.
