Urban Soundmarks Psychophysical Geodimensioning: Towards Ambient Pointers Geosystemic computation

Through interaction with environmental parameters such as light or sound, urban and architectural spaces generate ambiences with identifiable characteristics. This notion of ambiences is related to the human being position through its perception of environmental physical phenomenon during a pedestrian walk. Presented work aims to evaluate, so as to characterize, the impact of sound ambiences (soundscape) onto an urban pedestrian pathway using GIS spatial dynamical mapping. To carry out this scheme, our research work within AMBIOFLUX project concerns spatial interaction between sound ambience (soundscape) and man urban spatial trajectory (soundwalk). Spatial impression of soundsources or soundmarks has to be both defined through acoustical measurement and perception informational evaluation. The remainder of this paper is dedicated to the evaluation’s methodology of the pedestrian pathway’s acoustic fingerprint using the GearScape spatial formalism described thereafter. Preliminary results we have obtained will also be presented and validated.

A « perlaborative » environment for sustainable cities design staff in a participative perspective. GIS and knowledge database

Geolocalized photographical pictures realized during urban walkthrough are able to constitute a pertinent research matter for pedestrian emotional and semantical effects perception and representation acknowledgement. Ideoscenic-images manipulation processes analysis enables infra-logical access to visual ambiances recorded with the parameterized camera (framing, point, density…). So-producted knowledge is then integrated in a so-called perlaboration environment for urban planning actors.
