Xgobi and Xplore Meet Virgis

In this paper we report on a linked environment of the three programs XGobi, XploRe, and ViRGIS. While XGobi and XploRe are statistical packages that focus on dynamic statistical graphics and provide analytical statistical features, respectively, ViRGIS is a 3D Virtual Reality Geographic Information System (GIS) that allows real{time access to, and visualization of, geographic data. The XGobi/XploRe/ViRGIS environment is based on the Remote Procedure Call (RPC) technology previously developed for the ArcView/XGobi/XploRe environment. It allows linked brushing and the exchange of data and commands | completely transparent to the user.
