Furthermore, we tested different software applications for the processing of the imagery. Specifically, NDVI derived from multispectral UAV imagery was used to inform the determination of the integrity of the wetland vegetation. Here, we evaluate the performance of low altitude multispectral UAV imagery to determine the state of wetland vegetation in a localised spatial area. Applications of these sensors for mapping of wetland ecosystems are rare. The focus on the usage of these sensors is mostly directed towards the agricultural sector where the focus is on precision farming. The use of multispectral sensors on Unmanned Aerial Vehicles (UAVs) was until recently too heavy and bulky although this changed in recent times and they are now commercially available.
