Gis Open Sit is an operational tool at the service of the Public Administration for the census of house numbers, driveways and minor taxes (ICP, COSAP). It is a platform that allows the management of the census through a graphic dashboard and Android App for geo-referenced survey in the field. The survey and census activities can be distributed and assigned to several operators to make the operational and organizational process more efficient, with digital documentation and photographic surveys to support. The graphic dashboard allows analysis, reporting and export of data in different formats for subsequent import to third-party systems. GisOpenSit, in fact, allows to optimize the digitization of revenue collection and management processes right from the detection in order to allow an integrated view of debt and credit relationships with third party operating systems and processes and improve results performance. Gis Open Sit allows you to maximize the knowledge of the territory with the timely and digital detection of the information necessary for the calculation of the single tax and to minimize errors.
