In the specific context of the Territorial Intelligence, taking some socio-ecological foresight constraint into account, there is a clear requirement of an advanced Geographic Information System with semantic abilities. Indeed, being able to overlay and do some geoprocessing on several spatial thematic layers is a sine qua non but not enough condition. What is strongly required is a systemic approach that includes the anthropocentric view as a fundamental data. To achieve such an ambitious objective, we combine several types of indicators: from urban morphological one such as the partial isovists field (a useful tool to characterize the open space concept, that is the void where the urban pedestrian is immersed) to the (human-processed) soundscape signal through an adaptation of the entropy calculation. The aim of our paper is both to present the GearScape geoprocessing tool and to develop this multi-dimensioned indicator.
