ABSTRACT 
In many organizations, particularly local governments, there appears to be interest not only in GIS but also the 
linkages between GIS and seven closely associated geographic data technologies: 
- Document Scanning System (raster-based imaging system) 
- Image Processing System 
- Vector GIS 
- Raster-based GIS 
- Tabular DBMS 
- Computer-Aided Drafting and Design System (CADD) 
- Video Media System 
- Surface Modelling System 
Solutions for integrating these technologies will be one of the next major steps in GIS application evolution. 
This paper discusses a conceptual framework for the integration of these technologies and its implementation 
in the context of the ARC/INFO system.
