In late 2016, L’Avion Jaune conducted a unique photography mission on the Bolivian altiplano in the region of Uyuni. This area, at an altitude of 4,000 m, has produced quinoa for centuries. It has a unique archaeological heritage which has been the subject of few studies to date, and of mapping campaigns even less. Photos taken by kite enabled us to gather brand-new data that can be used to generate 3D models and contribute to a detailed understanding of this farming and social structure. A mine of new information for researchers which will be the subject of thrilling scientific articles.
Drone applications for agriculture are regarded as the growth sectors of the future. For L’Avion Jaune, the future began more than ten years ago when it produced its first digital NDVI maps by drone. At present, it is implementing powerful mapping resources capable of mapping entire regions.
L’Avion Jaune is installing Boreal systems on behalf of OLAM International to map tens of thousands of hectares of palm oil plantations. This drone system proved its capabilities by mapping 60,000 hectares of plantations to a resolution of 10 cm in the infrared spectrum. The work was spread out over four weeks, mapping 13,000 hectares per hour of flight, a task made easier by good relations with the Gabonese aviation authorities.
Vineyards have been a favourite theme for L’Avion Jaune since its inception in 2005. Its activities in this domain developed gradually from the field of research and, helped by its partnership with Fruition Sciences, a Languedoc-based start-up specializing in oenology, they are growing every year. Every summer, L’Avion Jaune flies over the vineyards of Bordeaux, the Languedoc and the Rhône Valley to produce maps for various purposes aimed at optimizing winegrowing techniques – a valuable and rapid service (80,000 hectares in a matter of days) for a sector constantly striving to improve quality.
The Camargue is a natural, mixed environment the evolution of which is being closely monitored. It is fragile, and work is being undertaken to preserve it. Consultancy firm Alisé Géomatique has been tasked with providing a status report. Hélène Durand explains how L’Avion Jaune’s aerial photos contribute to achieving this objective:
“This second image acquisition campaign for the new update conducted for the Camargue Regional Nature Park enabled us to precisely fix the dates on which the photos were to be taken. That meant we could plan a field check the same day as the image acquisition, which is invaluable for assessing the state of certain crops (for example, whether fields have been mown or not). The radiometric quality of the ortho-rectified images was excellent and enabled us to distinguish the 52 items in this very rich nomenclature by manual photo-interpretation. This 2016 land use update was delivered to the customer in August 2016, just two months after the images were acquired, which is unheard of at this level of detail.”
Gendarmerie : système de cartographie de crise
In the event of local crises, it is important for the national gendarmerie to have rapid access (less than four hours) to printed maps to distribute to its forces and be able to organize resources on the ground. L’Avion Jaune therefore developed a helicopter-based device that can be used to produce the desired data – a highly efficient solution of use in numerous types of event, such as natural or industrial catastrophes.
Region Réunion has a satellite system capable of mapping the entire southern zone of the Indian Ocean, especially the island of Madagascar, which is often affected by natural catastrophes. For its own local needs and to achieve higher resolutions over smaller surface areas, it was looking for a modular system to mount on a light aircraft. Starting from there, L’Avion Jaune invented and developed the PIMANT system and it delivered it on-site. This unique piece of equipment is capable of producing multispectral maps complementing the satellite images for fast and economical close monitoring and updates of optical data.
