This repository serves as a short guide to

• acquire data with a UAV and
• process data via Structure-from-Motion (SfM)

Aim of the workshop (01.03.2023)

• Get to know what kind of equipment for different UAV systems is needed
• Get to know how to plan and perform a UAV flight
• Get to know how to use a GNSS receiver to acquire Ground Control Points (GCPs)
• Acquire own data with an UAV.
