WHAT IS FOSS?

                 “It is a gift culture, where the basics are
                 taken care of and social status is gained
                 by giving things away, rather than
                 accumulating.” (Harvey and Han, 2002)

                                                 GIS & SWMM:

                                         • Take advantage on GIS
                                           complex functions available
                                         • Better characterize the model
                                           and analyze modelling results
                                         • Data archive, access and
                                           manipulation

                                           Directive 2007/60/EC

                                      “(18) Member States should base
                                      their assessments, maps and plans
                                      on appropriate ‘best practice’ and
                                      ‘best available technologies’ not
                                      entailing excessive costs in the
                                      field of flood risk management.”

CONCLUSIONS

                 • inp.PINS – interoperability between GIS & SWMM
                 • FOSS advantages:
                        – Reduced costs
                        – Tools adapted to users' needs
                        – Standards: interoperability

                 • FUTURE WORK: EPANET
                 • LIMITATIONS:
                        – Dependent on EPA software developments
