Background
As an open-source solution, DIPAS was developed by the administration for the administration and with scientific support. The system is continuously being developed further.

Creation of DIPAS
DIPAS was launched in 2017 as part of Hamburg's ‘Digital First’ strategy to rethink digital citizen participation in urban planning. It was based on the project ‘Finding Places’ (2016) by the CityScienceLab (CSL) at HafenCity University (HCU): using analogue planning tables and a digital extension, citizens were able to collaboratively locate and develop ideas in workshops.
After the successful pilot project, the Hamburg Senate commissioned the Department of Urban Development and Housing (BSW), together with the Agency for Geoinformation and Surveying (LGV) and the CSL, to combine CityScope technology with an online participation tool to create an integrated system. DIPAS was tested step by step in real-life procedures and scientifically supported.
Today, it has evolved into a flexible, data-based participation tool that is continuously being developed by the administration, academia and urban society.
Further development of the open source software
DIPAS was set up as an open-source-solution. The open software was made available under a GPL licence in February 2021 to other cities, institutions and research facilities for reuse and further development. The repository on BitBucket contains all the files and instructions necessary for DIPAS to be installed by the city's own IT department.
DIPAS and the software behind it are continuously being developed.
In the ‘Connected Urban Twins’ (CUT) project, for example, the cities of Hamburg, Leipzig and Munich worked together to implement and improve DIPAS. By transferring the software from Hamburg to Leipzig and Munich, technical, structural and practical components could be adapted and tested.
The DIPAS user community brings together cities, companies and research institutions that use DIPAS, exchange information about its use and want to shape the future of the system together.
