Abstract. In this paper, we present a methodology to fusion 3D visible and thermal infrared (TIR) information on coastal landslide area located in Normandy, France. A reflex TIR camera on-board an Unmanned Aerial Vehicle are utilized generate model using Photogrammetry. Python-written algorithm is then used associate the scalar closest point cloud, before applying α-blending ease visualization of both data sets. This leads generation integrated thermo-visible model, allowing direct analysis...
Electrical Resistivity Imaging (ERI) is one of the most used techniques in geophysics. As for many imaging methods, Digital Elevation Models (DEMs) are required to consider complex topography conditions. In this paper, we present some developments implemented into a new 3D-ERI software optimized context. The article focuses on forward problem and discusses (i) meshing methodology that directly DEMs processing several profiles where electrodes not necessarily aligned (ii) aspects taking...
Abstract. We present geophysical and remote sensing measurements on a flood dike, in the framework of Polder2C’s Interreg European Project (https://polder2cs.eu/). Electrical Resistivity Tomography (ERT) Ground Penetrating Radar (GPR) profiles have been performed alongside across dike. The are then combined with Digital Terrain Model (DTM) caarried out RGB visible camera board an Unmanned Aerial Vehicle (UAV). Integrated 3D results enrich data interpretation form basis for future experiments.
Saltwater wedge is a natural phenomenon defined as the displacement and retention of saltwater in freshwater aquifer. This saline intrusion can modify content dissolved elements coastal aquifers, which have consequences for water use (drinking or agricultural), on ecology, environment, erosion coasts, stability structures.This study focuses integration coupled interpretation various geophysical optical data obtained ground by drone to evaluate seawater chalk cliff Sainte-Marguerite-sur-Mer...
Summary This study presents the work carried out at Notre-Dame-du-Val chapel located in Sotteville-sur-Mer (Normandy, France). Local authorities are considering restoration and have requested a geophysical survey of surroundings. First, aerial photography by drone yields Structure from Motion (SfM) model exterior chapel, completed 3D interior model. Geophysical prospecting consists imaging shallow surface surroundings, with help Ground Penetrating Radar (GPR) Electrical Resistivity Imaging...
