Geoweb 2.0 for Participatory Urban Design: Affordances and Critical Success Factors

In this paper, we discuss the affordances of open-source Geoweb 2.0 platforms to support the participatory design of urban projects in real-world practices.We first introduce the two open-source platforms used in our study for testing purposes. Then, based on evidence from five different field studies we identify five affordances of these platforms: conversations on alternative urban projects, citizen consultation, design empowerment, design studio learning and design research. We elaborate on these in detail and identify a key set of success factors for the facilitation of better practices in the future

Public Participation GIS for sustainable urban mobility planning: methods, applications and challenges

Sustainable mobility planning is a new approach to planning, and as such it requires new methods of public participation, data collection and data aggregation. In the article we present an overview of Public Participation GIS (PPGIS) methods with potential use in sustainable urban mobility planning. We present the methods using examples from two recent case studies conducted in Polish cities of Poznań and Łodź. Sustainable urban mobility planning is a cyclical process, and each stage has different data and participatory requirements. Consequently, we situate the PPGIS methods in appropriate stages of planning, based on potential benefits they may bring into the planning process. We discuss key issues related to participant recruitment and provide guidelines for planners interested in implementing methods presented in the paper. The article outlines future research directions stressing the need for systematic case study evaluation

Web-based PPGIS application for participatory spatial planning in context of bikeability

Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial TechnologiesThe spatial planning processes are complex and require public participation to get insights about important problems and development of the neighborhood from the communities during final decision-making. The traditional participatory methods offer limited two-way communication just inform the public rather than to obtain suggestions from them and few public can participate due to time & location restrictions. Due to low public empowerment, they do not know how their participation can influence the spatial planning and decision-making process. This study tries to design and develop the web-based Public Participation GIS application with the integration of the internet, public participation, and GIS technologies to increase public participation during spatial planning and decision-making to overcome the limitations of traditional participatory methods. The web-based PPGIS application development is based on open-source technologies and allows the participants to visualize spatial data layer, perform spatial analyses and contribute to increasing and improving the bikeability of the city. The user study experiment is conducted to evaluate the usability and usefulness of the application. The evaluation results show that the web-based PPGIS application is easy to use with a System Usability Scale (SUS) score of 84.6 and an effective approach to increase public engagement and give suggestions on the spatial planning process and decision making

Seafloor characterization using airborne hyperspectral co-registration procedures independent from attitude and positioning sensors

The advance of remote-sensing technology and data-storage capabilities has progressed in the last decade to commercial multi-sensor data collection. There is a constant need to characterize, quantify and monitor the coastal areas for habitat research and coastal management. In this paper, we present work on seafloor characterization that uses hyperspectral imagery (HSI). The HSI data allows the operator to extend seafloor characterization from multibeam backscatter towards land and thus creates a seamless ocean-to-land characterization of the littoral zone
