DIPAS is a digital participation system. It combines Hamburg’s online participation tool with digital planning tables to create a seamless and integrated digital system for citizen participation. With DIPAS, citizens can access digital maps, aerial images, plans, 3D models, urban planning designs and, above all, urban geodata from home, on the move or at events and provide precisely localized feedback on planning projects. Contributions can also be commented on, discussed and evaluated. A quantitative live evaluation is transparently visible on the site. The feedback collected from citizens is evaluated following the participation phase and is incorporated into further planning.
Since the end of 2022, it is possible to automatically display all of a city’s DIPAS procedures via interfaces on an overview page, the so-called DIPAS navigator, and to obtain further information, for example on procedure topics and senders, as well as active and past procedures and their location in the urban area.
