In this session, explore how using technology like orthomosaics, contour lines and point clouds mosaic images can be amassed and 3D models can be created.

Drones seem to have the potential to revolutionise numerous areas of our lives, but today their biggest disruption is in the field of surveying and mapping. These small flying machines have made mapping any area or an object a matter of few minutes or hours, instead of the typical days or weeks it used to take before. In addition, latest mapping equipment enables operators to achieve survey-grade accuracy in a photogrammetric map or 3D model.

But what exactly is this ‘accuracy’? How do you define it, measure it, and verify it? And finally, what is the accuracy you actually need and how do you achieve it using UAVs? In this online CPD learning session, Harry Atkinson, co-founder of Sensat, and Ben Craigie, survey manager at Sensat, will explain the degree to which the absolute accuracy approaches the relative accuracy is determined by the overall quality of the photogrammetric process and the accuracy of the Ground Control Points.

Key Learnings

• Learn what a drone can and cannot do                                             
• Understand how data requirements match platform and operator
