The generation of 3D building models from Very High Resolution geospatial data is now an automatized procedure. However , urban areas are very complex and practitioners still have to visually assess the correctness of these models and detect reconstruction errors. We proposed an approach for automatically evaluating the quality of 3D building...

The automatic generation of 3D building models from geospatial data is now a standard procedure. An abundant literature covers the last two decades and several softwares are now available. However, urban areas are very complex environments. Inevitably, practitioners still have to visually assess, at city-scale, the correctness of these models...

The automatic modeling of urban scenes in 3D fromgeospatial data has been studied for more than thirty years.However, the output models still have to undergo a tedious taskof correction at city scale. In this work, we propose an approachfor automatically evaluating the quality of 3D building models.A taxonomy of potential ...

City modeling consists in building a semantic generalized model of the surface of urban objects. These could be seen as a special case of Boundary representation surfaces. Most modeling methods focus on 3D buildings with Very High Resolution overhead data (images and/or 3D point clouds). The literature abundantly addresses 3D mesh processing...

L'imagerie hyperspectrale (IH) est à l'heure actuelle encore trop peu considérée, pourtant ses spécificités en font un auxiliaire de poids pour le suivi des éléments du milieu urbain. Le projet HYEP a pour objectif de proposer un panel de méthodes et de traitements appliqués à l'imagerie hyperspectrale tout en comparant à celles d'autres...

he HYEP project (ANR HYEP 14-CE22-0016-01 Hyperspectral imagery for Environmental urban Planning - Mobility and Urban Systems Programme - 2014) confirmed the interest of a global approach to the urban environment by remote sensing and in particular by using hyperspectral imaging (HI). The interest of hyperspectral images lies in the range of...

A strong intern dynamic characterizes towns, a very high spatial heterogeneity of their elements, their 3D geometric shapes (horizontal and vertical) inducing shadows, and their large variety of materials. These characteristics make the collection of information of land surface properties and urban descriptors more delicate. Due to the...
