... The potential uses for geodata in the context of the national information infrastructure (NIp reach far beyond current uses, making current limitations even more disheartening. If legacy geodata, data generated by new technologies such as geoposition~ng systems, and 0th-resolution, satellite-borne sensors were easily accessible via networks, and if spatial data of various kinds were compatible with a wade range of desktop and embedded applications, the effects would be revolutionary in Nit application areas such as emergency response, health and public safety, military command and control, fleet management, traffic management, precision fanning, business geographies, and environmental management.

... These three technologies and new database management systems capable of handling multidimensional data will play an important role in operations decision support systems, maintenance management, and asset management wherever assets and processes are geographically dispersed. As the NIT concept challenges organizations to adopt more comprehensive, enterprise processing models based on we-area, multimedia communications technologies, there is a growing need to invest the NSD!

... A significant issue faced in recognizing the necessity of such an ~nteroperability mechanism for geoprocess~ng is that He geoprocess~ng community has been slow to adapt many recent advances in mainstream information technology. Traditionally, GIS packages (whether commercial or public sectors have created hippy structured and architecturally closed operational environments, tightly coupling display graphics with spatial analysis mechanisms, and relying on a tight coupling of spatial analysis with proprietary spatial database designs.

... also provide the means to create an extremely capable resource browser that users wait employ across networks to find and acquire bow data and processing resources. Searches wall be executed using powerful, object-oriented distributed database technology developed to handle large, complex, abstract entities that cannot be managed In conventional relational database management systems.

... Just as a Microsoft Word user can now run analyses on a Microsoft Excel spreadsheet embedded In a Word document without changing applications, a GTS user Will access (through the development of the OGIS and the object technology environments a full set of GIS capabilities while working in an application that may not be a GIS application. Just as the Word user no longer needs to convert the spreadsheet to tab~el~m~ted text before importing Me static data into the Word document, the GIS user will not need to convert data formats and projections.

The OGC board spealcs on behalf of both public- and private-sector users interested In finding more integrated and effective ways to use We world's Increasing wealth of geographical information to support problem solving In such areas as environmental mon~tonng and sustainment, transportation, resource management, global mapping, agricultural productivity, crisis management, and national defense. The OGIS Project Technical Committee of the OGC operates according to a formal consensus process structured to be fair and equitable and to ensure the technical completeness of the specification.
