GAT: Geological Analysis Tool

Abstract

[en] This project arises to help researchers of the Faculty of Earth Sciences to analyze geographical accidents, making an effective link from the photometric images to 3D models, both obtained by photometric devices, such as LIDAR (Laser Imaging Detection and Ranging). The 3D input data is a set of a large number of points so that its treatment tends to be slow and requires good memory management. Therefore, in this project, we have carried out the analysis, design, implementation, and validation of an application that allows the management of projects consisting of a series of images, the calibration data of the cameras, and a point cloud (3D model). This application helps the user to digitalize 2D points based on the images, taking into account their projection on the 3D model. We focus on the usability of the program, its accuracy, and its robustness concerning the storage of the data and in the operations of digitization. Thanks to this app, researchers could analyze the fractures of geological formations in different locations as well as they could predict future landslides.
