IHE Lectures on Flying Sensors and image processing

On 13 and 14 June 2018, HiView and FutureWater have jointly organized a short course for IHE, the UNESCO Water Institute that is based in Delft. Martijn de Klerk, from FutureWater, and Jan van Til, from HiView, conducted lectures on Flying Sensors with a focus on the application in water management and agriculture.

On the first day, the group of students was given flight demos at a farm in the Hoeksche Waard containing potato, sugar beet and wheat fields. Here the students were shown the different possibilities of Flying Sensors, with demonstrations of a fixed wing aircraft and a quadcopter. On the second day of the lecture, students processed the images taken by the Flying Sensors. Students learned to create NDVI (Normalized Difference Vegetation Index) maps with the help of open source software like QGIS and ICE. This helps farmers to identify crop stress and respond in a timely manner before crop damages occur. Moreover, farmers can reduce water, fertilizer and pesticide use by having accurate data on hand to tackle only the problematic areas.
