The Finnish city of Hyvink\u00e4\u00e4 has developed a unique internet service for collaborative 3D city planning. It gives real estate owners, investors, developers, designers, authorities, and citizens easy-to-use tools to publish their 3D plans and ideas for the built city environment.<\/p>\n Participants can comment on the 3D plans directly in the city model. The 3D app is integrated with Facebook, which enables further conversation.<\/p>\n During the last three years, the city has started experimenting with how to connect models with web-based city development processes. Tiihonen has initiated three government-supported KIRA-digi experimentation projects to accomplish the task.<\/p>\n Before starting at the city of Hyvink\u00e4\u00e4, Tiihonen had worked on numerous GIS and IT projects. In addition, she had produced several multimedia products for consumers.<\/p>\n \u201cI\u2019m enthusiastic about developing IT applications for consumers and citizens so that we can reach and engage them,\u201d Tiihonen says. \u00a0\u201cThat\u2019s why we wanted to make 3D city models easily accessible using a Web browser as the interface.\u201d<\/p>\n The first KIRA-digi experiment <\/a>in 2016 was built for an architectural competition to design a residential development project. It allowed both the jury and residents to study and comment on the competition entries in a realistic 3D environment \u2013 anywhere, anytime \u2013 using only a web browser.<\/p>\n Hyvink\u00e4\u00e4\u2019s second KIRA-digi experiment combines and extends the results of its previous project. It focuses on using 3D models for collaborative urban development.<\/p>\n \u201cMy initial idea was inspired by the augmented reality of Pok\u00e9mon GO. As a citizen, you could walk around the town and, with your mobile phone, see how a particular place might look in the future,\u201d Tiihonen describes.<\/p>\n Both city employees and private enterprises develop building plans for the city. It is also important to consider the opinions and ideas of the citizens. Tiihonen wanted to give every party involved an opportunity to present their plans, ideas, and comments in the 3D model. She contacted Annukka Lehtonen<\/strong>, the business director of Hyvink\u00e4\u00e4; Anitta Ojanen<\/strong>, the city planning manager; and Petri Kokko<\/strong>, CEO of Sova3D<\/a>. Together, they devised the second experiment, \u201cBrowser-Based 3D City Model for Collaborative Urban Planning.\u201d<\/p>\n The project aims to offer a user-friendly, visually striking solution that can serve the city\u2019s own organizations, private companies, and residents. Based on feedback from users, the project has, so far, reached its goals.<\/p>\nBuilding the 3D City Model<\/h2>\n
