The purpose of this project is to design, implement, and assess a prototype Temporal Geographic Information System with integrated multivariate spatiotemporal visualization capabilities. The prototype will include: (1) a fully-integrated multi-representational, multi-scale database model which integrates object-based, location-based and time-based representations, (2) a parallel approach for highly efficient data storage, retrieval and manipulation, and (3) a multi-dimensional, multi-scale visualization capability which facilitates exploratory and traditional analysis of time sequences of three-dimensional data.
The system proposed will be implemented in a UNIX workstation environment and use real-world data in assessing system functionality. Although each component of the proposed research will have independent utility, the principle contribution of the research will be the basis it establishes for building integrated Temporal Geographic Information and Visualization systems (TGIS/GVIS) that will support a full range of environmental science and decision support applications.
