Summer seaweed algal mat coverage on the intertidal Ledano Mudflat, Côtes d’Armor, France, was successfully capture by the drone team at CEVA in late summer (Sept.22). This follows similar work in Spring (May 22); all this useful data of photo footage will be used to confirm the different types of coastal vegetations when compare with satellite images from these areas.

These connections of rich data and photo footage will help a more accurate development of the interactive mapping toolkit for detecting seaweed algal mat and other coastal vegetations using earth observation technology. In other words, satellite images will be more useful to identify the areas being impacted by eutrophication as well as explosive seaweed algal mat growth and help to implement appropriate management actions, such as nutrient remediation and water quality restoration efforts.

Natural England drone team was also gathering drone photo footage from the Langstone Harbour Intertidal mudflat, the Solent, England in late summer (Sept.22). The imagery was captured using the 10-band multispectral with bands that match in with Sentinel and Landsat. The GSD was 5cms. We had mixed weather conditions, however flights were successful at heights of 72m and out to 480m ranges.

With the multispectral sensors on the drone, we can achieve a very high resolution around 5 cm (GSD). Also we are using pre-flight programming to ensure good spatial connection in the photo imagery. Stay tune for more updates.

We will be holding a workshop at the University of Portsmouth on the 3rd November 2022.

Please register your interest to attend this event. We plan on sharing project findings and having exciting discussions on the next steps for nutrient remediation in the Solent and further afield.
