Urban trees are equipped with beacons that connect via Bluetooth to a tailor-made app. The app is used for phenological monitoring, to display microclimate measurements and to broadcast information on the tree's regulating ecosystem services. We demonstrate an exemplary application of environmental monitoring in a young citizen science project. This approach and setting is scalable to other citizen engagement and VGI projects. The study design, and consequently, the results, fosters 1) an understanding how urban trees are in sync with the urban climate, and 2) deepens our understanding of systemic feedbacks which is key for implementing this understanding in urban tree management. Results show inter-species differences in the length of the growing season as a measure of the delivery of regulatory and cultural ecosystem services and as a response to urban heat island intensity.

The general goal of a smart city is to increase citizens’ well-being through sustainable development. Three-dimensional city modeling plays an increasingly important role in advancing this goal. According to Austrian architect, Christopher Alexander, city models can be considered to be composed of two parts, negative (building) and positive (open outdoor) spaces. Open outdoor spaces can have a significant impact on citizens’ well-being, but current 3D city models leave outdoor spaces almost empty, apart from the shapes of buildings, despite their key importance in cultural mapping. To close this gap, we propose a citizen science mapping project to improve the quality of existing 3D city models by crowdsourcing 3D imagery of public spaces and visual art artefacts.
Citizen Participation via Digital Maps: A Comparison of Current Applications

The effects of digitization on social coexistence have been a subject of controversy not only since the increased use of social media for political campaigns. But digital platforms are also being developed which, from the perspective of spatial planning and geography, enhance communication between administrations and citizens at the local, municipal level. These applications are being developed in relation to three areas: (1) the everyday experiences and competences of citizens in dealing with geomedia, especially using smartphones; (2) the individual process design for a particular participatory case; (3) the desired societal or local political benefit. This paper deals with these three aspects and discusses five selected examples of how digital participation platforms can be designed to include the use of geomedia. Based on experiences with the proprietary development of the web application PUBinPLAN in particular and on its comparison with other platforms, insights can be derived with regard to success factors as well as to opportunities and risks.

Designing user-friendly Public Participatory Geographic Information Systems (PPGIS) is a challenging task, since a PPGIS is typically used by users of different characteristics and having different requirements and needs. Hence, applying Human–Computer Interaction (HCI) principles is of particular importance in designing PPGIS. This study aims to create an inventory of usability aspects of a PPGIS by focusing on understanding the characteristics of a broad range of users. The usability study included 73 participants from Colombia, Uganda and Austria. We combined a custom qualitative survey (conducted in all three countries) with an eye-tracking based survey (conducted only in Austria). Especially participants with low levels of IT-literacy faced considerable usability problems. This was mostly due to a lack of experience in using functionally complex smartphone applications or interactive maps. In general, we observed a high level of difference in usability between the user groups. The eye-tracking statistics for the Austrian study supported the outcomes of the qualitative survey well.
