Evolution of the MOSS geographic information system for 32-bit computer systems

The authors discuss the current status and plans regarding the 32-bit implementation of the Map Overly and Statistical System (MOSS) geographic information system. Increasing interest in this system is promoting significant expansion of its capabilities, but any such enhancements will require careful analysis and planning to ensure that the resulting system is functionally complete and efficient yet flexible enough to adapt to a variety of user requirements and systems. All enhancements must be coordinated among centers of development in order to ensure the continued viability of a single MOSS. A baseline software configuration must be defined, and procedures must be developed to ensure coordination of any modifications to the baseline. Finally, there is significant interest in maintaining the public-domain aspects of MOSS to promote its shared use in the Department of the Interior. For these reasons, coordination efforts such as those initiated by the IDCCC and the MOSS Users Workshop should be strongly supported by the MOSS user community.
