Testo completoThe detailed characterization of large area is a challenging task because time and resources are frequently limited. This Master’s thesis is part of the ParaChute research project. The aim of this project is to develop a rockfall susceptibility rating system along linear infrastructures. A partially automated method has been developed to facilitate field works planning while optimizing time and resources. It is mainly based on 3D rockfall simulations carried out systematically and efficiently on every rock slopes located nearby the infrastructure to help identify potential hazardous natural cliffs. Automation tools were developed to allow the realization of simulations over large area. The proposed method also uses the software Rockyfor3D and only requires surface elevation model obtained from airborne LiDAR survey as input data. However, other data, such as orthophotos, were used for calibration. The method was applied along the ArcelorMittal Infrastructures Canada railway. The covered zone starts near Port-Cartier (Québec) and extends 260 km north along the ArcelorMittal Infrastructures Canada railway up to the Groulx Mountains. In this Master’s thesis, a partially automated method that helps to choose on which areas to focus field work by telling if there is a possibility for a block to reach the linear infrastructure is detailed.

Testo completo3D MRDB (Multi Representation Data Base) population is more and more required to support advanced cartographical applications and advanced geospatial decisional analysis. This dissertation presents a new photogrammetric approach dedicated to multiple representation acquisition process to populate the buildings of a 3D MRDB. The proposed approach is named SAISIE (this French acronym matches with a semi-automatic acquisition process, initialized and supported by human intervention). The SAISIE approach tackles simultaneously the Detailed Geometries (DG) extraction and the Simplified Geometries (GS) extraction. This uses both the Multi-Representation Acquisition Pattern concept and the Instance Driven SASS concept (SASS : Selection of the Algorithms, Sources and Setting) to improve the process performance. These two new concepts have been introduced during this research. The MRAP concept stems from bridging together the geometric pattern concept (used to support generalisation process) and the parametric model (used to support the photogrammetric building extraction). Two new algorithms have also been introduced. The first one deals with the automatic implantation of 3D geometric pattern and the second one with the automatic extraction of building footprints. The SAISIE approach, the new concepts and the two new algorithms, have been implemented and tested with four test sites. These test sites cover more than three hundred buildings. Results analysis and several recommendations, based on our experimentation and experience, are proposed to conclude this dissertation.

Testo completoAeolian dunes at different scales (m-km) are the primary topographic forms in aeolian systems and are found on various planetary bodies such as Earth, Mars, or Venus. They result from the interaction between wind, transported sediments, and the substrate. The shape, size, spatial arrangement, and movement of dunes allow for the analysis of interactions between airflows and sediment supply, modulated by surface conditions. The production of detailed maps of individual dune characteristics, coupled with spatial morphometric statistical analysis, is thus necessary to understand better and characterize the origin of dune formation and evolution.However, accurately mapping dunes over large areas remains a challenging task today for two reasons. Firstly, considering the availability of remote sensing datasets with ever-increasing spatial (and temporal) resolution, such mapping requires automated processes since manual digitization i) is time-consuming and ii) can be subjective and of uneven quality. These limitations are mainly because human operators cannot maintain consistent mapping criteria across large study areas, especially when dealing with complex morphologies. Secondly, this mapping is challenging, particularly due to the complexity of some forms and the lack of a universally accepted dune classification, despite recent research efforts.The primary objective of this work is to propose a new method for mapping aeolian dunes, focusing on an approach that couples Deep Learning to delineate the dune outlines, "skeletonization," and network analysis to map their crestlines and connectivities (defects). The originality of this study lies in the ability to map these features at various scales, ranging from a few kilometers to entire deserts. The developed algorithms demonstrate excellent performance in analyzing large and complex geographic areas with an accuracy of around 90%. This method has enabled the creation, for the first time, of a database containing several thousand dunes from the Rub'Al Khali desert (the largest active desert in the world), with high fidelity compared to visual observations of the dunes present in the Digital Elevation Model (DEM).From this database, we studied the morphological variability of the dunes by comparing them with wind data (ERA5 Land Reanalysis) on a desert scale, in order to quantify and understand their morphological changes and spatial distributions in relation to wind dynamics. This spatialized morphometric analysis is based on Principal Component Analysis (PCA) and highlights the dominant parameters as follows: dune length (PC1) explains more than 50% of the variance and describes the linear dunes in the SW of the desert; height (PC2) represents 18% of the variance and describes the crescent-shaped dunes in the NW; and defect density (PC3) explains 14% of the variance, representing star and dome dunes in the SE. P-value tests were also conducted on these parameters and revealed values below 0.05, thus confirming a significant spatial organization of dunes at the desert scale.Each archetypal dune form is dominated by one of the three parameters identified by the PCA, and transitions between these forms represent evolutionary stages. By comparing these results with wind data, we obtain an evolutionary model in which dunes shape, size, and orientation are strongly influenced by the directional characteristics of sand flow associated with the Shamal and Kharif winds. The analysis of wind data to the different statistically defined dune populations also revealed two dune growth modes: an elongation mode in the west, where the crests of linear dunes align with the sediment flow, favoring their stretching, and an instability mode in the east, where isolated and crescentic dunes, perpendicular to the flow, optimize their vertical growth
