In order to be compliant with the law, French cities have to set up their own tax management system for car parks starting from January 2018. In this objective, Marseille, the second biggest french city, has appointed APMS, a leader in the car park business for 25 years, to provide a complete and detailed state of the city’s parking lots. APMS has chosen the imajing technologies to achieve this objective. More than 19 000 parking places were surveyed and digitized with imajing solutions. These data will contribute to set up the municipal tax policy on car parks and later manage it as a smart city.
