Dynamic Graphics in a GIS: A Bidirectional Link between ArcView 2.1 and XGobi | An Update

This article reports on a bidirectional link between a Geographic Information System (GIS), ArcView 2.1, and an interactive dynamic graphics program, XGobi. ArcView 2.1 allows calls to external procedures via Remote Procedure Calls (RPCs) and it also enables external programs to invoke ArcView 2.1 functions using RPCs. These features enable us to provide a bidirectional link between ArcView 2.1 and XGobi. Our link combines the dynamic, interactive strengths of XGobi for visualizing high dimensional data with the map handling tools of ArcView 2.1, speci cally to explore spatial data. This article presents information about the technical realization of the link and it addresses substantial questions such as security and concurrency issues. However, the main focus of this article is to address a new audience in addition to the statistical community. To achieve this goal, several parts have been reused from previous publications on this topic by the same authors.
