Aerial Surveys



Terrain Surveys can provide Aerial surveying services through the use of Unmanned Aerial Vehicles (UAV) or more commonly termed ‘drones’.


An Aerial survey is carried out using a UAV to capture high definition imagery of a site which can then be processed to produce various deliverables. Our survey background ensures that the data captured is survey grade & fit for purpose.


UAV’s allow rapid and safe data capture of large areas in a very efficient manner which can prove to be a very cost effective alternative to conventional surveying methods. The use of drone technology also allows us safe access to areas which were previously inaccessible.


There are many benefits & applications for the use of drones in the surveying industry, please contact us to discuss how our expertise could benefit your project.

What is aerial surveying?

Aerial Surveying is an accurate representation of the area of interest showing all natural and manmade features with levels. Shown as three dimensional points all features including the property, land features and physical boundary details are presented on a scaled survey drawing. Using our aerial surveying equipment one of our aerial survey teams will visit the site to capture the site features and then process the information at our offices in Welwyn.

What information is included in an aerial survey?

The amount of detail included in an aerial survey depends on your requirements. Typically the aerial survey will include the existing buildings and structures, boundary details, a grid of levels, ground surfaces, tree positions, drainage details and service cover positions. Additional details can be included such as the features adjacent to the site or underground services. Survey drawings are normally delivered as CAD files and as scaled paper plans.

How do I obtain a quotation for aerial surveying?

A quotation can be sought by contacting us with the details of your site with as much information as you have. This can be the site address and post code with a description of the site extents, but any existing plan information you can supply is always useful. One of our experienced aerial surveyors will then provide a proposal detailing our fee, aerial survey scope, timescales and the deliverables.
