In the context of a research about application of dynamic visualisation parameters in animations for monitoring purposes, this paper reports on characteristics of dynamic geo-spatial phenomena for visual exploration. A framework of concepts is proposed to describe a variety of phenomena in the physical environment. The nature of monitoring tasks is taken(More)
We designed and applied interactive visualisation to help an urban study group investigate how suburban residents in the Tallinn Metropolitan Area (Estonia) use space in the city. We used mobile phone positioning data collected from suburban residents together with their socio-economic characteristics. Land-use data provided geo-context that helped(More)

Remote sensing image repositories are the fastest growing archives of spatio-temporal information. This leads to large time-series that geoscientists need to explore and understand. Effective exploratory tools are urgently needed to handle the large data sets efficiently. Common application areas that require such tools are, amongst others: climate change(More)
This paper concentrates on developing methods to effectively visualize uncertainty and fuzziness in animated representations by various combinations of graphic and dynamic visualization variables, and selecting or developing a method by which the usability of uncertainty and fuzziness displays in spatial planning maps can be evaluated. As a case study,(More)
Geographic information technologies are evolving from stand-alone systems to a distributed model of independent web services. In parallel, voluminous geographic data are being collected with modern data acquisition techniques such as remote sensing and personal navigation devices. There is an urgent need for effective and efficient methods to integrate and(More)
