Current geographic information systems (GISs) have been designed for querying and maintaining static databases representing static phenomena and give little support to those users ...
Conceptual design involves requirements analysis, functional specification, and architectural design. It remains informal and poorly understood. We studied the conceptual design a...

Hypertexts may be implicitly structured, based on either node content or context. In this paper, we examine implicit structures that rely on the interpretation of node’s spatial...
