DONNEES - Stage Cartographie des risques sismiques
<p>FRANCAIS</p> <p>Cet entrepôt contient les données (shapefile, vidéos) utilisées lors d'un stage sur la cartographie des risques sismiques. Le reste des documents est disponible ici : https://github.com/berenice-lm/stage-M2-Cartographie-des-risques-sismiques.git </p> <p>Le projet consiste à créer une carte interactive et multi-échelle lisible pour les sapeurs-pompiers à partir de données de tremblements de terre estimées par le BRGM. L'objectif est de fournir très rapidement aux gestionnaires de risque une carte qui puisse les aider à agir efficacement sur le terrain, en attendant le retour des données de terrain.</p> <p>Le stage avait pour objectif principal de recueillir les besoins des sapeurs-pompiers (ateliers, entretiens, etc.) en matière de cartographie. Une phase de création de carte s'est ensuivie, avec une attention particulière portée à la généralisation cartographique (comment adapter les données à chaque échelle pour rendre la carte lisible) afin d’éviter de désorienter les utilisateurs, ce qui pourrait être d’autant plus préjudiciable dans une situation nécessitant une réaction rapide. Une phase d'évaluation de la carte, à l'aide d'un eye-tracker pour suivre le regard des utilisateurs, a ensuite permis de déterminer si la carte proposée correspondait à leurs attentes.</p> <p>La suite du stage consisterait à automatiser la création de ce type de carte pour produire en quelques minutes un outil puissant pour les sapeurs-pompiers.</p> <p>ENGLISH</p> <p>This repository contains the data (shapefile, videos) used during an internship on seismic risk mapping. You can check the rest of the documents here : https://github.com/berenice-lm/stage-M2-Cartographie-des-risques-sismiques.git</p> <p>The project involves creating a readable, interactive, multi-scale map for firefighters, based on earthquake data estimated by the BRGM. The objective is to quickly provide risk managers with a map that can help them act effectively in the field while awaiting the return of on-site data.</p> <p>The primary goal of the internship was to gather the firefighters' cartographic needs (workshops, interviews, etc.). This was followed by a map creation phase, with special attention given to cartographic generalization (how to adapt the data at each scale to make the map readable) to avoid disorienting users, which could be especially detrimental in a situation requiring rapid response. A map evaluation phase, using an eye-tracker to monitor users' gaze, then allowed us to determine whether the proposed map met their expectations.</p> <p>The next step of the internship would be to automate the creation of this type of map to produce a powerful tool for firefighters in just a few minutes.</p>
