The project presented in this paper aims at enforcing the INSPIRE Directive on a local scale by extending the capabilities of this SDI in order to providing on-demand geospatial web processing using the WPS Standard. This would enhance the current uses of the SDI by pooling all the processes built by IRSTV researchers and engineers – noise mapping, flooding modeling, atmospheric pollutant dispersion, etc. – and by creating a geospatial knowledge repository to study cities. These processes would then be accessible to the federation’s partners: local authorities, agencies, citizens, private organizations and companies.
