GIS Databases: From Multiscale toMultiRepresentation
Graph Chatbot
Chattez avec Graph Search
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.
Remote sensing and geographic information science offer many pos- sibilities in terms of availability of diverse data. Some products like land cover layers or digital elevation models can be extracted from imagery and enable the realization of 3D city mode ...
The recent availability of geospatial information as linked open data has generated new interest in geospatial query processing and reasoning, a topic with a long tradition of research in the areas of databases and artificial intelligence. In this paper we ...
We propose a semiautomatic procedure to generate land cover maps from remote sensing images. The proposed algorithm starts by building a hierarchical clustering tree, and exploits the most coherent pixels with respect to the available class information. Fo ...
Gaussian random fields are widely used as building blocks for modeling stochastic processes. This paper is concerned with the efficient representation of d-point correlations for such fields, which in turn enables the representation of more general stochas ...
To make successful predictions in ungauged basins (PUB) exploring how to facilitate the identification of catchment characteristics from readily available information is as important as improving the theoretical representation of different hydrological pro ...
The recurring challenge facing anyone who tries to localize realities in order to show their spatial relations on a map is the systematic impermanence of any objectivized space. Thus any space used as a base layer in thematic maps must be thought of as the ...
The number of cross-border workers in Luxembourg has steadily increased for over thirty years. In the collective imagination the cross-border workers come to the Grand Duchy just to work. The purpose of this article is to overcome this representation by me ...
Many studies have suggested that the motor system is organized in a hierarchical fashion, around the prototypical end location associated with using objects. However, most studies supporting the hierarchical view have used well-known actions and objects th ...
Modern cartography, grounded in the Euclidean concept of space and the mathematization of its language, has laid the foundation of academic geography and promoted its epistemic emergence as a scientific discipline. Developments over the last decades and th ...
GPS devices allow recording the movement track of the moving object they are attached to. This data typically consists of a stream of spatio-temporal (x,y,t) points. For application purposes the stream is transformed into finite subsequences called {\em tr ...
