Black rhino right hind footprint captured to WildTrack’s protocol for the Footprint Identification Technique (FIT)
Yes, you are reading correctly. Namibia it was again! This time with a team made up of Drone Adventures, Skydio, Cyril Gliner an aerospace engineering student from London (Imperial College), and the team at Kuzikus Wildlife Reserve where we all met to undertake a research project for WildTrack and Kuzikus.
Every year the Drone Adventures team heads out to complete a project altogether. Besides reviewing all aspects of a drone mapping mission, from planning and preparing to capturing the data and processing, it’s also about having a great time together!
A collaboration that involves drone experts, the University of Milan, the Association Mani Tese, and local communities to improve the management of the Mau forest in Kenya.
This mission is a follow-up of the Eigenthal and Rothenthurm bogs mapping, previously conducted with Pro Natura. The goal is to collect data to perform hydrologic simulations, and plan better the future work to preserve the bogs.
With already over 15 missions under our belt, we have mapped just about any landscape with our drones. But the one thing we haven’t done yet is to give marine conservation a hand. Mapping St-Joseph atoll in the Seychelles and acquiring high-resolution aerial images to identify shark and ray pups seemed like the perfect challenge to introduce our drones to the salty and wet air of marine conservation.
What happens when you mix ancient Bushmen knowledge with the latest in drone technology? Our experiment of joining these two very opposite worlds presents a completely new way of counting wildlife.
Exactly one year after our first mission to Namibia for the SAVMAP project, a team made up of Drone Adventures, EPFL’s LASIG lab and Kuzikus Wildlife Reserve came together again in the Southern African savanna from May 16 to 23, 2015 to apply last year’s findings and push the limits of civilian drone use for nature conservation applications one step further.
Protecting endangered animals like the Black Rhino and plants like the endemic and fascinating Welwitschia mirabilis, proposing new ways of managing land sustainably in semi-arid savannas and finding new approaches to counting wildlife were all important topics on our agenda this year.
Timothée Produit of EPFL’s LASIG lab was part of our Namibian mission in May 2014. During the mission, Tim gave lectures both at the Polytechnic of Namibia as well as at the Gobabeb Research & Training Center on how to use the acquired drone imagery to classify terrain. Once all the imagery of the mission had been processed back home in Switzerland, Tim went on to use our data for classification purposes.
In this blog, we explore how to use multi-spectral imagery acquired by the eBee, processed into orthomosaics using Pix4Dmapper, to create vegetation base maps.
Most Drone Adventures missions to date have involved using eBee mapping drones to assist humanitarian projects. However in recent months we have taken part in an increasing number of environmental conservation projects too, such as our recent Namibia mission.
Here in Switzerland we were contacted by Pro Natura, a non-profit conservation organization with over 100,000 members, to help with a unique biodiversity project – using drones to create orthomosaics and terrain models of an ancient peat bog in need of regeneration.
Following the redevelopment work of site one, the presence of so much surface water and tufts of new dark green vegetation now indicate a healthy site.
