Espoo's 3D City Model Hackathon
From 9th till 11th October 2015 the Energizing Urban Ecosystems organized at the “Stage” in Aalto Design Factory, the first 3D City Model Hackathon of the city of Espoo focusing on how 3D City Models can serve as an innovation platform for Smart Cities.
Short video presentation of the whole event by
9th - 11th October 2015, Espoo, Finland http://3dcitymodelhackathon.com/
The goal of the 3D City Model Hackathon was to create applications related to city planning, urban digitalization, living, traffic & transportation, energy and environment that utilizes the 3D City Model of Espoo and open data provided by the organizers. The open questions were:
How can the 3D City Model Serve as an Open Innovation Platform for Smart Cities?
How to Combine a 3D City Model with Real-time Energy, Traffic, or Mobile Phone Data?
How can 3D Gaming Technologies Utilize 3D City Models and Data from the Databases of the City?
How a 3D city model and Open Data are utilized to support University Campus and Otaniemi area restaurants, cafés, events, and facility management?
How can the Internet of Things Benefit from 3D City Model?
How to utilize Open Data and Open Interfaces In 3D City Models?

The Hackathon offered a series of presentations from several companies, Institutions and Individuals who also mentored the participants during the three days. In-between, there was time for discussions, team building and to work. The participants had to apply for the hackathon via an online form and preference was given to software developers, designers and urban innovators with a desire to provide new services and applications to improve the living in the so strongly branded Smart Cities.
A series of APIs, software and 3D models were offered to the participants to hack upon. At the end, a total of 9 teams from over 70 participants came out with different proposals. These were offered several prizes for their work according to different categories.
The event was moderated by Pedro Aibéo who also belonged to the organizing team composed of himself, Jussi Lehtinen from Espoo City and Oskari Liukkonen from the company Sito.
The event was a collaboration between the Espoo City, Aalto University, Sito, Elisa, IBM, Slush, Futurice, Colossal Order, Unity, Tietoa, Fira, Virtual City Systems, AEC Hackathon Helsinki, Helsinki City, Gispo, Architectural Democracy, VTT (Technical Research Centre of Finland) and Kone

City of Helsinki
„People who are making 3D city models, 3D semantic models in Finland it’s such a small group, it’s like a family it’s like a thing we had in the 90s when we were doing GIS work or CAD (...) We have few people here in Finland so if we do it separately the same things it doesn’t work at all.”
Aalto University Campus & Real Estate
"The goal is for Otaniemi is to be energy self-sufficient"
Director, Wizardry and Development
„What we are talking about for openness is that businesses and the city and users can put their data together so that you have very low friction among them for adding a new service"

"About our Elisa Hackathon challenge for you: How to engage citizens to participate in city development?"
A construction company building in Jatkäsäri in August 2016. Mikael offers a set of data that might inspire some of the „Hackers“: „We have temperature data of all the individual apartments in that data model, that’s about it. We hope you can use this information somehow and let’s see what you guys come up with.“
Against the usual believe that big companies move slowly, IBM is putting up digital platforms such as the Bluemix: „What I am presenting today is the IBM Bluemix, which is the platform as a service which is the offering that we have, and it is more than that, it is more like a digital innovation platform.“
„How 3D city models, how they’ve been before and become open and usable for general public.“
Lucas van Walstijn
Virtual City Systems
"We create high performance web visualization of city models"
„You don’t want to limit your possibilities or your ways or ideas to go into the proprietary closed up source data, API’s Standards or whatever“

"Less time for introduction, more discussion!"
3D City Models & Unity
"Our user cases are, costum solutions, avatars, spatial engines"
"Complexity, City, 3D Model, if we are to empower citizens to add information to it, we have to give away for them to understand it in a fast and easy way and to empower, to edit it, if they don’t understand it, they will never do it"

Summary: Estia group developed a data-driven adaptive lighting and way finding system that promotes space sharing for energy saving and also allows the building to communicate with people through lighting and multiple devices.
They started this Hackathon by thinking about how buildings communicate with people. How can all the data of buildings such as heating, electricity usage, water usage, and occupancy be effectively communicated to the people who are using the building.
The whole concept was to avoid buildings where one receives the information through smartphones but to have a system that integrates the information with the actual interior design and the architecture of the building.
At the back end there is an analytic model of energy data to visualize such data in a deeper way for people to understand how they use their energy.

Plan P group proposed a fast and easy-to-use urban planning tool that compares and analyzes relevant information. It enables one to see the impact of new buildings and play around with ideas. It is aimed for city planners, decision-makers, activists, and citizens.
The problems the team wanted to solve were:
- planning new buildings is complicated
- it is not easy to take certain aspects into consideration
- the impact of a (new) building is hard to predict
- data is often distributed on several Platforms/Programs
- data is often only visible in 2D
The idea, one tool to (rule them all):
- plan new buildings
- get information about the impact of buildings
- combine all the available information
- virtualize buildings and their environment
- see the 3D buildings and the 2D information at one glance
With Plan-P You can...
… look at the 3D model of Otaniemi
… look at various data presented in colors on the map
… add new buildings to the model trying to achieve planned targets, for example certain square meter amount
… analyse the impact of (new) buildings
… analyse the impact of environment/climate change

Samuli Kuusisto firstname.lastname@example.org
Samuli Kuusisto represented Stereoscape Oy, a Finnish company that uses interactive 3D animation, virtual reality and other tools of the digital age to deliver high-impact product visualizations for marketing, sales, training and other applications. The demo is an early phase of a solution that delivers a sort of interactive BIM model for the construction industry to pre-market apartments and buildings. It was made with Unity 5.2 using pre-existing 3d model of Otaniemi area provided by the 3d City Model Hackathon.
The user can zoom in multiple ways, rotate around the target (pre-selected building), control the time-of-day and cloudiness, hide and show a building façade, choose a stair, room count and floor of the building and when pressing ‘select’ button the code shows the available apartments in the building according to the user’s selection. The visualization is created by manipulating cost-effectively pre-existing CAD- and IFC-models. The visualization is upgradeable, and it can be made use of in various contexts, for example in different phases of a building project and in diverse marketing channels.

Representing their own company, Beigeharmaa which does real-time visualization and motion graphics, they used the three hackathon days to implement their real-time voice recognition based navigation which runs on unity 5, into the 3D city model of Espoo. The Espoo city data model that they received from this Hackathon has a much higher level of detail than the Helsinki one they worked before. In the presentation they showed the real time demo by using its voice controls.
A draft version of the project can be found at the GitHub repository:
You can find the voice recognition by Api.ai Unity implementation based on api.ai Sample Unity app at:

This application developed along these 3 days by these 2 individuals had, in contrary to other groups, no backing from previous ongoing projects. The main idea was to access tweets (for the experiment sake, the 3D City Hack Tag were used) and with it, one could see the activity of events geo located. This was shown via a tweet logo on the building of the design factory. One thus knows that there is a gathering of people in that location and anyone can click on such logo to access all the live tweets. The idea of getting people’s location to optimize services is a current one that clashes with the desire of many to keep some features private. Some of the Q&A focused on that point in which the group replied as this not having been designed as a consumer product.

The problem the group tackled was that when one is designing cities one often makes miniatures out of them but there is still quite a gap between the virtual model and the physical model. It was thus intended to make an augmented reality application that would function as a bridge between these two. Basically the functionality is that you can put different textures in the models and by scrolling on a bar you can see how in a few years’ time the materials will look like in the real world.

Summary: The basic idea is that when one doesn’t know where classrooms are one can turn on the application, one inputs where you are and where you want to go and then you can see a 3D model that takes you to the location, including indoor navigation.

Maps in itself are not that exciting, one needs to build services on it to make it exciting. This team proposed and partially implemented geo-referenced and virtual reality information into digital maps by using a different set of sensors of smartphones.

Hackathons are important alternative tools within our ever changing teaching and collaborative system. One designates time to focus solely on one project (instead of the daily multi-tasking), most commonly for a few days around a problem or a challenge based on software. It is a collaborative environment to turn ideas into reality.
Often so, such events are used by companies or individuals to develop their ideas further and pitch them. But there are also individuals who are teaming up and from scratch, they bring about new solutions. Such shows one of the big qualities of Hackathons, its flexibility.
The promoters of this event understood that there is a high number of engaged people who have plenty of ideas and knowledge on the topic of smart cities, who are eager to collaborate with larger projects and institutions. These events are both solution generators and networking enablers and promote a spirit of collaboration and openness. The event served this purpose fully and ought to be be repeated within similar formats.
