Call for Papers & Deadlines

The workshop is a follow-up to the successful workshop on Visualization, Analytics and Spatial Decision Support at the GIScience’2006 conference. Selected papers from the previous workshop, including the Setting the research agenda paper, were published as a special issue of IJGIS, v.21(8), 2007.

The workshop supported by the Commission on GeoVisualization of the International Cartographic Association aims at bringing together researchers from relevant fields to address research issues of geospatial visual analytics in the multidisciplinary context of GI Science.

A big part of data that the modern society deals with has both spatial and temporal characteristics. Visualisation of spatial and temporal data traditionally belongs to the research area known as geographic visualisation, or geovisualisation. Geovisual Analytics (short for Geospatial Visual Analytics) extends geovisualisation research by enhancing purely visual and interactive methods with new possibilities provided by computational techniques such as data mining, statistics, and optimisation. Potential enhancements come also from developing methods to support analytical reasoning, argumentation, knowledge building, and knowledge communication.

The frontier research problems in Geovisual Analytics involve the scalability of tools and their usability. The goal of the workshop is to present the most advanced methods and applications of geovisual analytics, discuss problems and possible approaches to solving them, and define appropriate directions for further research.

Major scientific topics to be addressed:
- scalability - how to make visualisation suitable for huge data sets (e.g. with the help of database technologies and data mining);
- usability - how to fit the tools to the needs, abilities and conditions of different categories of users (for example, domain experts vs. decision makers);
- effectiveness - how to ensure the effectiveness of visual analytics tools and how to test and prove it;
- innovative visually driven methods of data analysis addressing the problems of scalability, usability, and effectiveness.

Challenging applications of geovisual analytics:
- decision support: - generation, evaluation and comparison of alternatives,
- accounting for uncertainty of decision recommendations,
- explanation, justification, and communication of results;
- education: - enhancing learning and knowledge transfer;
- scientific research: - acquiring new knowledge;
- collaboration: - supporting communication, cooperative problem solving and knowledge construction.

Authors are invited to submit original research contributions or application reports in English. The authors are requested to stress the multidisciplinary character of their approaches and their relevance to the theme of the workshop. We encourage submissions presenting early stages of cutting-edge research and development, as well as submissions from PhD students.
