Summary: Drone technology is evolving quickly for a wide range of applications, including water quality monitoring. It provides flexibility on when and where to collect the data, and it makes it easier to observe areas that are physically inaccessible. Not only that, the results provide high spatial detail. This paper will discuss their use in mapping water quality and discusses Texel as a case study.

  • Challenges of airborne drone technology for water quality assessment
  • From raw drone data to turbidity maps
  • Demonstrated at a dune construction site in Texel under clouded sky
  • Validated with in-situ water samples
