Aerial photography by drone taken as part of agricultural land mapping (Commune of Carcans, France).

Elaboration of an Ortho-Photography of vineyard plots of Château Beauséjour (Commune of St Emilion).
The ortho rectification and assembly of the photographic plates were carried out with the PIX4D software.
Export in Geotiff format allows the image to be integrated as an analysis support in a GIS (Geographic Information System) or spatial analysis software processing chain.

Production of a Digital Terrain Model (DTM) and ortho-photographic supports in Ivory Coast for a cashew nut plantation.The documents were produced from photographic images acquired with a Dji DJI Phantom IV drone.

In order to guarantee the geometric coherence of the photogrammetric point cloud and the precision necessary for hydrological studies (flow model),geodesy work and determination of support points (topographic canvas) was carried out by our teams.

Ortho-Photography of the roof of the National School of Magistracy (Commune of Bordeaux).

The intervention with the DJI Mavic 3E drone was carried out as part of a study for the repair of the roof and frame of the building.

Photorealistic 3D model of Château Conti (Commune of Isle d'Adam - 95) produced as part of a public lighting study and used for radiometric simulations.

The 3D mesh (Mesh) comes from a photogrammetric calculation from photographic images with 20 M pixels.

Drone survey of the castle for the purposes of producing roof and facade plans with nadir and oblique shots.

Drone inspection of the roof to identify sources of thermal leaks as well as defects(cracks, corrosion, foreign bodies, etc.) in order to assess the maintenance plan to be implemented.

Fusion of topographic data from terrestrial and bathymetric surveys.The realistic color data (RGB) comes from a Lidar topographic survey campaign acquired by Drone.

The data visible in solid green to red color comes from a campaign of bathymetric measurements.The unification of data makes it possible to obtain a comprehensive digital terrain model with an accuracy of around 10 cm.

Thermal monitoring mission of hot spots and fumaroles on the Domaine d'Hostens site following the fires in summer 2022 due to the persistence of lignite fires.

Monitoring is carried out using a drone equipped with a thermal camera (ZENMUSE H20T) allowing detect temperature variations between -40 and 550° C according to a flight plan listing the “risk zones”.

Extract from an Orthophotography of Cap Ferret (Gironde) carried out as part of a study concerning the dynamics of the coastline.

Topographic survey on industrial site for cubature measurements of piles of wood chips for stock management.

Topographic survey of an industrial aggregate storage site in order to obtain a monthly stock report.

Recording and photogrammetric modeling of piles of wood logs for cubature measurements, and evaluation of extracted silvicultural volumes

Topographic and Thermal Survey in order to identify anomalies of all the panels of a photovoltaic power plant + 3D modeling from the table to the cell

A flight was conducted over a 25-hectare plot immediately after a storm to determine the number of fallen pine trees and the size of the corresponding trunks. Following the flight, the digital data was classified (ground, trunk, canopy, fallen trunks) and then calibrated (size, diameter at 1.3 m, etc.).

Acquisition of the entire municipal territory to obtain a point cloud.This high-density colorized cloud (750 pts/m²) is then classified (vegetation, buildings, soil, etc.).

Finally, the 3D model was produced from the existing constructions and the topography of the site.

Manual flight carried out to take oblique views in order to produce a very high density point cloud (3000 pts/m²) of the facade of the vestige.

This data makes it possible to faithfully restore the masonry apparatus with a view to its probable restoration.

As part of the Patronage agreement between the UNGE of Gironde and the SMIDDEST, Parallèle 45 contributed to the creation of a digital twin of the Cordouan Lighthouse with centimeter precision.

Production of facade plans including 1 'stone by stone' plan of the bell tower, based on a digital twin (point cloud) of a 19th Century church.

For conservation purposes, we created a twin of the memorial and georeferenced all the pathologies related to the monument's deterioration over time. The photo corresponding to each pathology can be viewed online.

Video acquisition of a common multi-network trench with the aim of producing a class A georeferenced as-built plan.

Modeling of pipes with a view to integrating the project into a BIM process.

Production of a digital model of underwater terrain on Lac Vert (Community of BIGANOS) as part of a road redevelopment project.

PARALLELE 45 does not own an aquatic drone. If we have to use this means of acquisition, we are using the rental of a drone system to receive our Teledyne T50P system or other multi-beam system.
