Project objective

Where are the best places for skating in Vienna? Where to go to escape the summer heat? Which is the best park for a relaxing afternoon with friends? The project CityOases collected with the help of citizen scientists and the CityOases app data on the potential use of urban open and green areas in Vienna. The observations and data help urban planners to make Vienna an even more liveable city, and also citizens to enjoy the city even more.

CityOases is a pilot project within the international project Landsense coordinated by IIASA and funded under the European Union's Horizon 2020 framework programme. The Landsense project has developed a citizen observatory and innovation marketplace for land use and land cover monitoring and runs various pilot projects in Europe, such as CityOases in Vienna. 

How did citizen scientists participate?

Users searched for specific activities in Vienna with the CityOases app, visited one of the points indicated on the map and evaluated the point. They were asked to name the activities but also to rate characteristics like noise, safety, cleanliness or attractiveness of the area. The information, ratings and a photo of the place were shared with others. Users also created and evaluated new points and added them to the data pool.

Conditions: Places had to be publicly accessible, outdoors and in the urban area of Vienna. 

What happened to the contributions of citizen scientists?

The observations and data submitted by the citizen scientists were shared with other users of the CityOases app, so they were able to access recommendations and ratings. Additionally, the anonymised collected data was made available as open data to the public including scientists, researchers, students and the city council. 


How are winners being determined
Two school classes and one individual with most observations will win. Only observations and evaluations made within the city border of Vienna during the competition period will be counted.
