Urban sustainability assessment in Geneva: Relevance of the local neighbourhood unit

François Golay, Melissa Pang, Claudia Rebeca Binder Signer

The physical characteristics of an urban system are typically heterogeneously expressed, creating distinct neighbourhoods shaped by specific local features. Hence, spatially explicit expression of sustainability across the urban system is expected and shou ...

Evidence of traffic-generated air pollution in Havana

François Golay, Alain Clappier, Jessie Madrazo Bacallao

In Havana, transport is blamed as a likely source of pollution issues. which is usually supported on arguments referring to a vehicle fleet mainly made of old cars (i.e., most models are American from the 1950s or Russian from the 1980s) with poor technica ...

Shifts in wind energy potential following land-use driven vegetation dynamics in complex terrain

François Golay, Jiannong Fang, Alexandre Buttler, Fernando Porté Agel, Alexander Ludwig Johannes Peringer

Many mountainous regions with high wind energy potential are characterized by multi-scale variabilities of vegetation in both spatial and time dimensions, which strongly affect the spatial distribution of wind resource and its time evolution. To this end, ...

Heuristic-driven Graph Wavelet Modeling of Complex Terrain

François Golay, Alexandre Buttler, Alexander Ludwig Johannes Peringer, Ioana Stoicescu

We present a novel method for building a multiresolution representation of large digital surface models. The surface points coincide with the nodes of a planar graph which can be processed using a critically sampled, invertible lifting scheme. To drive the ...

Pose Estimation of Web-Shared Landscape Pictures

François Golay, Vincent Lepetit, Devis Tuia, Timothée Produit

We propose a robust method for registering high oblique images of landscapes. Typically, an input image can be registered by matching it against a set of registered images of the same location. While this has been shown to work very well for images of popu ...

Analyse spatiale de la conflictualité, exploration par la régression géographiquement pondérée

François Golay, Stéphane Joost, Elisabeth Salazar

Cette recherche porte sur l’analyse spatiale de 1600 conflits urbains s’étant produits entre 1965 et 2000 dans le territoire correspondant aux limites actuelles de la ville de Québec. L’article propose de renouveler l’analyse de la relation entre la fréque ...

Modelling wind-driven rain on buildings in urbanized area using 3-D GIS and LiDAR datasets

Luca Rossi, François Golay, Claudio Magalhaes Carneiro, Pauline Emery, Sylvain Coutu, Vera Wyrsch

This study investigated the distribution of the fraction of rainfall intercepted by the facades of buildings located in an urbanized area. We used the frequently used semi-empirical standard ISO-15927-3 to simulate Wind-Driven Rain on facades. The implemen ...

Academic Cooperation to Foster Research and Advocacy Competences in the Occupied Palestinian Territory (West Bank)

Martin Schuler, Marc Soutter, François Golay, Claudio Magalhaes Carneiro, Béatrice Métaireau

Palestinians living in the West Bank, a territory occupied by the State of Israel according to International Law, face a deprived access to land and a limited ability to move freely which pertains to the presence of Israeli settlements and other infrastruc ...

Pose estimation of landscape images using DEM and orthophotos

François Golay, Devis Tuia, Timothée Produit, Christoph Strecha

In this paper, we propose a methodology for the estimation of the pose of oblique landscape images. Knowledge about the pose is needed for using such images in augmented reality applications or to allow projection of pixels in a GIS for spatial analysis. W ...

Remote-evaluation of user interaction with WebGIS

François Golay, Jens Ingensand

In this paper we propose a framework that characterizes user interaction with webGIS. Furthermore we present a technique to remotely test and evaluate such systems. Our framework does not only include parameters describing the usability of a system, but re ...
