vallue and geographic information databases. Integration of the information itself puts a radically different perspective on the work process. Staff now need to question how the information will be used and to what end in order to expli citly capture the relevant relationships of map elements in the database. This requires an information perspective. This, in turn, affects the tasks within the organization while at the same time new ones are created i.e. data base manager, database administrator, application pro grammers, etc. Decentralization The decentralization of production capabilities occurs when conventional expertise as expressed in software can be used by non-experts. Examples include GPS, digital photogrammetry, automated bank tellers and air line reservation systems. In our profession the most profound impact of this charac teristic is the loss of monopoly of governmental carto graphic production agencies. This requires a complete rethinking of mandates and recognition of how the power ful relationships shift between and inside institutions. A good example of this was the challenge levelled at the Ordnance Survey of Great Britain by the joint utilities, land registry and municipalities to accelerate by a decade or so the completion of the large-scale digital topographic database of Great Britain by reducing the number of feature codes drastically. The challengers had carried out a pilot project to prove their point, and the Ordnance Survey was faced with an unprecedented situation. This was during the period of the so-called Chorley Commis sion on the Handling of Geographic Information in 1986. However, the real exploitation of this character of the technology requires some kind of supporting infrastruc ture, such as the active control system for GPS, or the networks necessary for automated bank teller and airline reservation systems.

This infrastructure is the collection of electronic, physical, and education facilities, together with the databases policies and standards all of which govern and promote access to and use of infor mation. There is a growing literature on this subject. The re-evaluation of the mandates of national mapping agencies and the question of information infrastructure may lead to clarification of the mission of these organiza tions. This was reported in a study on the future of the national mapping division (NMD) of the U.S. Geological Survey by the National Academy of Sciences. ,,As the 21st century begins and this nations economy continues to be transformed by technology from one dominated by production utilizing natural resources, to one based on service, transportation and information, it will increasingly require the support of what might be called an information infrastructure. This infrastructure will include not only myriad data sets (and a spectrum of public and private sector organizations to create or gather them), but also complex systems for co-ordinating, storing, processing, managing and distributing them. From this perspective it would appear in the best national interest for USGS/NMD to be transformed prior to 2010 from a mapping service organization to the federal agency responsible for struc turing and co- ordinating the geographical or spatial component of the national infrastructure. Such a transfor mation can take place gradually, but it requires that clear vision of ultimate goals be in place so that all subsequent technological and institutional development occur in an orderly and purposeful fashion". Customization The technology promotes customization of products at relatively low cost.
