To exploit the potential of geo citizen science, technological solutions are needed that are tailored to the requirements of citizens and scientists. To create suitable solutions, participatory design is a valuable means. While information on techniques for requirement-gathering in cooperation with future solution users exists, less knowledge is available regarding implementation tools for creating solutions together with future solution users. One tool used in a professional setting is ESRI’s Survey123 for ArcGIS. The suitability of Survey123 for ArcGIS to implement geo citizen science solutions was evaluated within the citizenMorph project. The experiences showed that by using Survey123 for ArcGIS most requirements were met, but citizens faced a number of challenges using the citizenMorph solution developed.
Urban activity detection using geo-located Twitter data

More and more studies are based on freely available social media data. With microblogs the analyses of urban activities are possible. This paper is focusing not only on mapping human activities but also defining urban functionality in the city. Using geotagged Twitter data, separately spatial, temporal and spatio-temporal analyses are performed. Tweets are grouped by six activity groups: Work, Home, Leisure, Eating, Shopping and Education, based on chosen keywords. The results show stronger performance for Leisure, Eating, Shopping and Education activities and less successful for Work and Home activities. The first four are focusing in the centre of the city, while the rest are more scattered all over the city. Moreover, each activity shows its own temporal pattern. This study finds characteristic patterns for everyday activities and shows the possibility of using social media data for defining urban functionality for places where land use information is not available.
Citizen Science @ PLUS (University of Salzburg)
Marlene Ernst, Vera Strasser
Universität Salzburg, Österreich
There is more to citizen science than generating data. By involving the public in our research we break down barriers and make professional science more approachable. It’s all about cooperation and mutual respect. The contact point for citizen science at the University of Salzburg (established 2015) offers support to those interested in experiencing this research method.
