Introduction to Drone Mapping

This course will allow you to formulate a strong understanding around the core functions within Pix4D photogrammetry software. It is aimed at professionals who will benefit from the use of a photogrammetry capability, whilst typically deploying unmanned aerial vehicles for their day to day survey works. Pix4D & AgiSoft Photoscan are highly capable drone mapping platform that has many in-depth functions.

• This course does not need any prior drone related experience. Anyone can take it up!

What Will You Learn?

Our course offers students the opportunity to develop their knowledge of:

• Data Capture process including the use of capture apps.
• Environmental factors affecting data capture.
• Creation of georeferenced maps.
• Creation of 3D models.
• Phraseology and meaning of Pix4D & AgiSoft Photoscan processes.

The course is aimed at professional surveyors and consultants with little or no knowledge of photogrammetry processing, and is an essential step in taking your business operations to the next level.
