Abstract
Studies have proved that 80% of data has a spatial reference [1] and it would be reasonable to assume that the temporal reference has a similar relevance. Spatio-temporal data visualization assumes an important role in the data presentation to users. Offering a synchronized view on three dimensions of data (i. e. descriptive, temporal and spatial) helps users in their knowledge discovery process. In some fields, like Cultural Heritage, time assumes an important role to explore data. The same timeline could be view in different thematic context, temporal domain could be stratified and the time reference could be qualitative and imprecise. Managing this kind of features improves the ability of the users to recognize pattern in data. In this paper is presented a spatio-temporal data visualization application that shows a new method to explore hierarchical and stratified temporal domains with imprecise temporal reference. The application interface offers a high level of personalization. Users can choose between different type of views and visual metaphors to compare objects on geobrowser activating or disabling layers of their interest. Interface is open and extendible to new kinds of visualization.
