Abstract
Integrated environment for visualization and analysis of temporal information is immature, while there is geographic information system (GIS) which is integrated environment for spatial information analysis. Additionally, basic data, corresponding to base map and gazetteer for spatial information, is not available for temporal information. Needless to say, temporal information is an essential element in various scientific fields, and is important to link between different kinds of data in interdisciplinary studies such as area study and environmental study. In this paper, activities of HuTime project which is trying to develop software tools and to construct basic data for visualization and analysis of temporal information are introduced.
