Sharing the City

Improving City Life with Open Data

Biggest Ever Open Data Hackathon in Prague History
Applications closed

Hackathon: June 12th - June 14th at Node5
Preparation event: June 8th


Naše školy [WINNER]

Team: Marek Lisý, Šimon Rozsíval, Martin Egrt, Honza Kašpárek, Lenka Moutelíková, Tomáš Fejfar, Michal Zwinger

Naše školy is a platform for open school data that are currently not standardized nor stored anywhere publicly and thus can’t be used for school comparisons, search of free spots, etc. We build a storage platform with API and a showcase app to demonstrate what can be build on a properly accessible school data. We have used Prague 7 and Prague 8 school data to start with.

Used tech: node.js, elasticsearch, MySQL, PHP, Linux server, Azure

Parking in Prague

Team: Jan Egert, Petr Egert, Pavel Kolář, Jura Cibula

We make the driver happy by providing one empty parking place for her/his car. We help to drivers arrive at an appointment, the office or date on time. Our application has real-time information about the nearest parking place, and the driver can make a payment if needed. The driver saves gas, time and money. Do you need a parking place?


Team: Jakub Žitný, Felix Palmer, Jaroslav Jirava, Petr Čmela, Lenka Vraná, Jan Sovka

NeverRun is for everybody who commutes daily with public transport. It shows the position of transport vehicles all around you.. Now you know if you should rush to catch a metro train or relax instead.
We used data supplied by Magistrát hl. m. Prahy in order to simulate live server giving us position data of all means of transport. City of Prague is planning to launch a real server soon - and our app will be ready!

Used tech: PostgreSQL + PostGIS + PHP running on Microsoft Azure, D3.js library and Google Maps

City Activity

Team: Jan Egert, Petr Egert, Pavel Kolář, Jura Cibula

How does an ordinary day in Prague looks like? What happens around? Which places to visit or better avoid? Where your car will be probably towed or your child hit by reckless driver near school? Check our application displaying Prague real life rush in 3D!

WebGL + Babylon.js, Google API, PHP, Apache, MySQL

PragueHacks act as evidence of the potential of innovations behind the geo related data and technologies. Similarly in Danube region, despite the obvious demand, there is lack of similar initiatives. DanubeHack Bratislava therefore aims to meet this needs & thanks to inspiration from PragueHack, proposal for the event website development took place.

Link: (pick it up)

Team: Vojtěch Švec, Jiří Špác (pick it up) is about dog poop decreasing the quality of living in cities.
It collects data about:
dog poop that wasn’t cleaned up
position of dog poop bins
number of bags at the bins
Uses cases:
avoid leaving dog poop behind (dog owners)
improve quality of clean-up and bin maintenance (people / cities / companies)
We haven’t used any data at the moment, we’re creating a new data set.


Team: Josef Gattermayer, Dominik Veselý, Jan Brejcha

LuckyMe is a mobile application for iPhone and Apple Watch that lowers the risk of their users of getting mugged or assaulted.
Unlike crime maps it reports the situation in an actual location and an actual time. A quick look at a watch or a phone shows the actual risk rate on a grade from 1 do 5 - one can for example check the risk rate before entering a dark street. Single incidents can be repoted as well by users, either from prefilled (robbery, intoxicated person, fight, assault, vandalism) or just as a subjective feeling from a given location on a grade 1 to 5.

The risk rate is calculated from 3 data sources: data from ambulance, data from municipal police and data reported by users. Public datasets accordingly are filtered, we take only a selected types of incidents.

Technology: Native iOS, Cloudant (CouchDB)

Open Flats

Team: Radek Švarz, Tereza Praksová, Ondrej Ešler, Jindřich Mynarz, Michal Vrchota

WalkingAreas is a web mapping application that shows walking areas to Prague metro stops and selected train stations. In addition, each stop shows graphs of demographics The user of this app can click on the map to calculate walking areas and demographics in any location within the city of Prague.

Used datasets: Walking Paths from IPR Prague, Demoographics from Czech Statistical Office Census 201, Lines and stops from network: Train network: OpenStreetMap, Base map layer: OpenStreetMap


Team: Jan Kolář, Martin Chapčák, Vojtěch Kurka, Jakub Stejskal, Eliška Doležalová, Jan Kučera

The municipal infoboards contain valuable information, however, with thousands of unstructured announcementsit is hard to keep track. Signalizator gathers the information and assigns a geographic position based on its content. You don't need to search for relevant information anymore - you simply pick a street and get an alert when a new announcement appears.

We built our solution on Microsoft Azure using AngularJS, Leaflet, PHP, Java, Spring, Lucene and municipal data from


Team: Radek Švarz, Tereza Praksová, Ondrej Esler, Jindřich Mynarz, Michal Vrchota

CleanData (Open data pumps framework) will help to make open data being truly open with open source data pumps API framework, deployable onto the cloud platforms.

Input: original excel sheet nightmare data
Service output: clean data via API

The developers can just plug-in and consume the data without spending time and effort on integration and data cleanage.


Team: Albert Uchytil, Peter Malina, Vojtech Mašek, Anna Šubrtová, Adam Benda, Pavel Hübner, Martin Štěpař

Regular maps will always show you the fastest way to your destination. This is not always the best solution for people with plenty of time or those who want to explore.

WALKz is able to find the best path based on user preferences. Green areas, population density, noise pollution. Personalized ideal paths for everyone. Don't go through the main street if park route is available. Explore, relax and be healthy at once. Walk(z).

Walk. Run. Have Fun!

Used data: Green areas, noise, POI, walk routes, pollution, built-up areas, terrain height
Used tech: Bluemix, Azure, Node.js, OpenLayers, WinPhone .NET

Storyteller Prague

Team: Ondrej Tomčík, Dominik Paľo, Peter Malík

City break holidays are increasing in popularity. Before travel, you can prepare your trip, book guided tours... if you have time. But you'll never hear interesting stories which only residents fully know.
Our application offers mobile (offline) guided thematic tours like Golden Prague, Josef Lada, Romantic walk through Letnanske sady, Tour de Czech Beer, In the footsteps of Krtek. You will be guided through the city and listen the story. You can answer quiz questions and share it. You can take pictures from public cameras to prove you enjoyed it! You will receive notification about discounts in restaurants during your walk. You can buy audio guides for museums, churches, castles directly to your mobile. Find the nearest toilets, ATMs, police stations directly on the map. And many others.

Used technologies: Xamarin, Azure.


Team: Robert Arzumanov, Vojta Dlapal, Axel De Acetis, Petr Flégr, Alžběta Gardoňová

To participate in the Hackathon, you must pay a symbolic registration fee of CZK 250 per person, which will cover some of our costs, including food and drinks for you and your team for the whole weekend. This is a non-profit event.

In order for the Hackathon to run smoothly and productively, we will hold a Pre-Hackathon meeting, a week before the event. At that time, sample data sets will be made available, and data providers, including city officials, will greet participants. IBM and Microsoft will also give a quick orientation on their development environments. This way, you’ll you’ll have 1-week head start on deciding which data you’ll use, and which tools work best for you.

No way! This event is open to anyone who cares about the city- you don’t need to be a resident to apply. You can even camp at Node5, if you bring a sleeping bag and mat. The event’s official language is English.

Event Sponsors IBM and Microsoft will give free access and training to all Hackers on their latest cloud technologies: Microsoft Azure and IBM BlueMix. These tools allow developers to use their favorite programming languages such as ASP.NET, PHP, Python, Node.js and depending on the chosen platform use tools like Watson, Cloudant, Mongo DB, Twilio, Elephant SQL, BigInsights for Hadoop, BigInsights for Twitter.

Of course! You can even make the fruits of all your hard work open-source, if you want. There are no obligations, as long as you use the available Open Data sets and create something useful for the residents, businesses, or municipalities of Prague. That’s it.

Not at all. When the Hackathon kicks off, you’ll have the chance to pitch your idea to all participants, or to join a team you find interesting. Teams may combine or split up according to their interests and goals. Teams should consist of 2 to 5 people with diverse skills.

Why apply?

The Sharing City, like the sharing economy, is emerging as a new and growing force to empower citizens to play a larger role in their cities. The sharing economy is changing personal relationships, spaces and buildings in cities everywhere, including our beloved Prague. Shared housing, offices or vehicles allow us to efficiently and economically utilize shared infrastructure. But we must go further.
Sharing the city makes us more responsive to changes in the environment, the economy, and political and social life. It makes us more secure as well, and boosts our ability to build a fairer, stronger, happier city for all our fellow residents.

The 21st century city must utilize public data on shared platforms, allowing its residents to rethink and reinvent it from the inside. Together, using new knowledge and tools, the denizens of Prague can and must outline and demand government and business services that are simple, effective, and easy to access.
With the help of its Hacker residents, Prague can remake itself into a beacon of new solutions and forward thinking innovations, and inspire other cities to join it. The Prague Hackathon is a chance to unleash your imagination, and to reinvent your role as a citizen of our great city.
