Photogrammetry for geological research

 

Together with its partner Positics, L’Avion Jaune has built a Phase One iXU 1000 sensor into its M600 drone to produce very high-resolution 3D models of quarries.

This photogrammetric data will enable the geological and mining research agency BRGM to study the network of fractures in analogues of potential geothermal reservoirs.

The quarry model will enable us to reconstitute the network beyond levels accessible by foot, as well as to obtain quantitative information about the rock (dimensions, orientation, density).

Region Occitanie: beautiful images with a purpose

Since 2018, L’Avion Jaune has regularly captured images that combine technical information and aesthetics.

The Technical Services of Region Occitanie plan, monitor ongoing works, and inspect completed works in relation to numerous major infrastructure projects such as ports, railway stations, railway lines and airports. Funded by the Region, these facilities require photographic coverage of the different stages of development. Renowned for its technical rigour and practised eye, L’Avion Jaune undertook a number of magnificent aerial surveys serving multiple purposes – analysis, memorisation, testimony and communications.

Carried out in conjunction with Aerodata France, these missions are an opportunity for us to do our bit for the development and reputation of our beautiful region.

Lidar scanning at Neolithic village of Monte Revincu, Corsica

2019 got off to a great start with a mission from the Regional Directorate of Cultural Affairs – to survey the microrelief of the archaeological site of Monte Revincu in northern Corsica.

Overlooking the gulf of Saint Florent and the Agriates desert, Monte Revincu is the site of one of the best-conserved Neolithic villages of the western Mediterranean. During the course of excavation, some fifty stone-built domestic and funerary structures have been discovered, including two dolmens and foundations of dwellings.

The objective of lidar scanning is to produce a precise map of these structures and understand how they were integrated into the landscape in order to pave the way for more in-depth archaeological analysis and plan the development of the site.

For this mission, the YellowScan Vx-20 laser scanner on board a DJI Matrice 600 drone covered nearly 60 km and in 17 flights scanned more than 150 hectares. Also, using RTK GPS the fieldwork duo measured more than 200 control points on the structures uncovered during excavation. Operations were conducted over a timescale of five days due to the challenges of the extreme ruggedness of the site, the density of the maquis vegetation and the physical difficulty of accessing the take-off points.

But it was a successful mission for the team of L’Avion Jaune, who harvested more than 300 million data points!

Drones to map individual palm trees

OLAM Gabon commissioned L’Avion Jaune to supply a drone capable of mapping its tens of thousands of hectares of palm tree plantations. The operation was successfully completed with the provision of a Boreal system and in-situ staff training.

Archaeological mapping at 4,000m above sea level

Begun in 2016, the mapping of the pre-Inca sites in the region of Uyuni (Bolivia) continued in 2017. A fixed-wing drone mapping mission was conducted on a dozen sites located on the slopes of the Tunupa Volcano. The objective of these mapping missions is to understand the pre-Inca farming system of quinoa production. This data is of interest to the scientists of the CEFE ecology research centre for their anthropological and agronomic research.

A new product for vineyards

Winegrowers expressed the wish to see what was happening at the level of vineyard rows. Last summer, this wish was granted. New algorithms providing more precise images have resulted in the commercialization of a new product, at the cutting edge of cartography, for visualizing vineyard rows.
