Abstract
AbstractComputer-Aided-Design (CAD) is the emerging force to be reckoned with in the world of surveying and mapping. CAD provides the technology for mapmakers to integrate, at different degrees of sophistication, the many facets of map making into a linked information chain so that maps are easy to make, revise, view, understand and communicate. Implicit in the CAD concept is the recognition that maps, which represent the end products of the mapping cycle, are shared graphic databases to be used in other information cycles. The uses to which these graphic databases can be applied are only limited by the imagination of man. To harness the full power of CAD technology, standards for graphic interchange formats must be firmly established. This paper examines the problems of graphic database interchange standards from across the CAD spectrum: from microCAD to mainframe CAD, and looks at some solutions to these problems.
