Drone topographical survey

27 Feb 2018

We recently carried out a drone topographical survey of 10 acres of land using a number of ground control points (GCPs) (OSGB 1936) and achieved an RMSE accuracy of 2.75cm. 


The drone topographical survey video shows the high level of detail (65 million points) that can be produced by using this technology and specialised software. A drone topographical survey can produce a point cloud, DSM, contours and the orthophoto within google earth.


The drone topographical surveypoint cloud can be produced in a number of different file formats e.g. dxf, las, laz, xyz, e57 etc. and can be brought into CAD/BIM software for analysis/drawing.
