Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This portable system offers fast deployment with no recalibration and maps both vertical and horizontal features while maintaining optimal flight parameters. The geo-referenced image and 3D point-cloud data can be processed into digital terrain models, dig ...
This paper presents a self-contained, light and flexible mapping system that can be quickly deployed into inaccessible areas. Although designed to measure wind-transported snow volumes and the snow avalanche runoff over and experimental site, the system is ...
This paper discusses the integration of material flux analysis and agent analysis as the basis for a transition towards improved regional wood management in Appenzell Ausserrhoden (AR), a small Swiss canton located in the Pre-Alps of Switzerland. We presen ...

Among different dead wood types, large snags have a particular ecological relevance for biodiversity in forest ecosystems. For both research and management purposes, rapid and cost-effective inventories of large snags are required. Due to the great variabi ...
The Institute of Photogrammetry has developed a peripheral system for the automatic derivation of digital terrain models for the analytical plotter Kern DSR 15; this project is carried out in close collaboration with Leica AG. The principal component of th ...
