Only when GIS data and analysis have migrated from discrete systems and are available enterprise-wide, will end-users be fully empowered. Standardization in the multimedia world will be the conduit to bring GIS integration to large organizations. This trend began with the exploitation of multimedia and videodisk technology by GIS developers. |. Introduction In the mid 1980's, geographic information system developers began to exploit new technology in order to handle complex graphical information less expensively. Integrating optical disk technology and audio visual standards such as NTSC has become known as “multimedia”. One of the characteristics of both multimedia and GIS installations is that they tend to be specialized, discrete environments. The value of geographic information systems for rapid calculation and effective communication will only meet it's potential when it is integrated enterprise-wide on the desktop. Multimedia will be the vehicle to bring this about. This vision of GIS integration is not a new one, it has been articulated in varying ways by many people. The purpose of this paper is identify how multimedia is the vehicle to propel GIS corporate-wide, and that the technology is realizable today. 2. "Video Disk" GIS Applications from simple colour maps with a minimum of data running on a personal computer to weather system simulations on super computers fit into the general category of CIS. The processing and memory 391 requirements of higher-end GIS applications needed very powerful computing in the 1980's. The costs for integrating large amounts of raster and vector information made software expensive, reducing the penetration of GIS into organizations - even those that had a legitimate and immediate need for automation. Since the 1960's when the value of digital processing was proven to be more effective than analogue processing, there has been a general tenet in the computer industry that systems are only elegant when all the information is digital and collected in a vector format with all sorts of attribute information. This has not always been a practical approach. In the case of GIS, developers have had to make decisions regarding the usefulness of information as it relates to processing and memory ramifications. Video disk technology brought GIS to the personal computer without compromising the quality and amount of information that can be displayed. Although the information is digitally stored on a disk, it is in raster format and integrated with the computer through analogue inputs. A software database allows the linking of what are essentially pictures of hard copy maps with the computer. The system immediately shows the wealth of
