Abstract
Many applications of spatial information systems require not just spatial data handling but a unified approach to space and time. This paper begins by motivating this requirement with some examples, continues by identifying some of the key issues in this area and then discusses a unified generic model for information which is referenced to two spatial dimensions and two temporal dimensions (database and event times).Keywords
