Interactive Spatial Web-Applications as New Means of Support for Urban Decision-Making Processes

Abstract

<p><strong>Abstract.</strong> Citizen participation, co-creation – a joint development of professionals and citizens – initiatives for urban planning processes have increased significantly during the last few years. This development has been strongly supported by the evolution of Information and Communication Technologies (ICT). E.g., it has never been easier to get information through your mobile devices wherever and whenever you want it. Public open spatial data is available in many cities around the world and web-based applications use this data to provide tools and services for many different topics such as traffic information, or the communication of health-related information (e.g. ozone, particulate matter or pollen loads). This paper presents typical problems of such web-applications in terms of application design and implementation and usability evaluation via describing three case study applications which have been developed recently. It tries to answer the question: How can this kind of geo-services be developed and used by scientists to enable public participation within data gathering and urban planning processes? All three applications have the common goal to provide interactive geo-visualization and analysis features which are tailored to support users in their urban planning processes. The innovation of those applications lies in their flexibility regarding the topics they can tackle and their capability to perform interactive analyses triggered by the user. The applications have been built with a strong focus on exploring the available data (e.g. Open Government Data – OGD). Two of the applications have been implemented using the R-Shiny framework, the third application, the smarticipate platform, has been developed using ReactJS for the front-end, running a MongoDB in the background which is fed via a micro-service framework. In the latter application, the users can configure topics, i.e. the platform enables the user to create new services for different planning issues.</p>

CWDAT—An Open-Source Tool for the Visualization and Analysis of Community-Generated Water Quality Data

“…Participants indicated that the proposed method of statistical paired site comparison is a promising technique which could help to address the discussed barriers. Specifically, the reliance on publicly available datasets can leverage spatial open government data to the benefit of the CBM field, especially as this resource is typically underused outside of the scope of "expert" research projects [46] while remaining accessible.…”

Urban Planning Design and Evaluation Based on GIS Information and Bayesian Network

“…With the application of GIS in various fields, such as resources and environment, people gradually have a strong awareness of the proportion of spatial information in global information concentration, and various advantages of GIS gradually appear in front of people [15]. For example, GIS has a rich variety of software and application systems and has special features in the format, processing, and display of spatial data.…”

Performance Matters on Identification of Origin-Destination Matrix on Big Geospatial Data

“…The performance is measured in two aspects: spatial accuracy and run-time. The former DBMS has a natural linkage with QGIS due to its relational structure, whereas the latter is non-relational DBMS (NoSQL) that is commonly used in web-based applications (Gebetsroither-Geringer et al, 2018). In order to make the experimental results repeatable and improve their development, the source code of this research is shared on GitHub .…”
