CASE STUDY - UAV SURVEYS

At Grantham Coates Surveys we pride ourselves on continually innovating, developing and investing to stay both current and ahead of the field in all aspects of land surveying. To this end we have trained two UAV drone pilots and gained the all important CAA license to enable us to fly commercially.
 
We see UAV surveys as another tool in the box. UAV’s along with our laser scanning, sonar scanning and traditional survey tools make us well placed to carry out any survey anywhere in a timely, safe and cost effective manner. UAV surveys provide a remote controlled platform from which low level imagery can be captured.

Some of the advantages of UAV surveys are:

• Orthographic images along with 3d point clouds can be generated
• Survey difficult or dangerous to reach places
• Survey of areas not visible from ground level resulting in a more complete model
• Can supplement other survey methods e.g. ground based laser scanning
• Covers a wide area in a short period of time
• Fast turnaround of deliverables

Deliverables:

• 3D point cloud
• 3D mesh files
• Orthographic tiff images in plan and focusing on embankments

The survey was carried out quickly and without the need for direct access line-side.
