Generalization Operations and Supporting Structures

Abstract

Current GIS do not support wide flexibility for the performance of map generalization operations so users have limited opportunity for creating views of data at different levels of resolution. This paper describes a context for computer assisted generalization and reports on a set of generalization operators. The generalization operators are embedded within a larger scheme for a map design system which could be attached to a GIS. The selection and sequencing of operations is not fully automated but relies on user interaction. This approach is adopted to allow users maximum flexibility in tailoring maps to their individual needs. The system, however, is designed to provide substantial support for the user in negotiating this process. The final section of the paper describes data structures for supporting the operations within the context of this interactive environment.
