The local administration is conscious of these problems and tries to solve them to guarantee a global approach to urban management, to optimise former affords in data capture and database creation and management. This tendency is reflected in the physical integration of databases as well as in the release of several recent accordings between the data owning institutions. Nevertheless the digital network revolution is inevitably on its way and will soon solve the annoying transport problems. This does not eliminate the database access problems, but it reduces them to compatibility problems on the one hand and political decisions on data sharing and standardisation on the other. The WWW was originally developed to allow information sharing within internationally dispersed teams, and the dissemination of information by support groups.
Data sharing is controlled by access restriction on the Web.
The first approach requires the integration of all datasets into one standard system and the change of every administrative unit to this standard system. This would in long terms offer the ideal situation for management, but it is very cost intense and requires large political agreements. This general query has to be interpreted and transferred to the specific GIS software. The specific GIS software has to execute the query and summarise the results into a single file. This file has to be exported and transformed to be visualised on the WWW interface.
