2011) enhance conditions for developing modern information infrastructures. Quality 
and performance of appropriate infrastructure forms an important basis for the optimiza 
tion of cooperation, to increase productivity and to fulfill legal duties. 
The currently available tools do not meet these requirements. Important building 
blocks for the necessary networking have already been developed by NOKIS and the 
implementation of local spatial data infrastructures in various departments. There is still a 
considerable need for research and for standardization at national and European level in 
setting up functioning networks, which allow the use of harmonized and interoperable 
spatial data on the various administrative levels. 
VOGT (2002) highlights the importance of harmonization of data from different sources 
in the case of river basin analysis in the Guidelines for the implementation of the Water 
Framework Directive. It is a prerequisite for interoperable provision of geo-information 
by services to use interdisciplinary and distributed geodata (ARBEITSKREIS ARCHITEKTUR 
der GDI-DE 2007). The INSPIRE Directive establishes a strict time frame until 2014, 
in which documentation of data with metadata and data access with standardized network 
services for searching, visualization and download shall be implemented in stages. The 
MDI-DE project has been working on prototype solutions in this context. Section 2.1.5 
describes the sustainable platform for future conceptual and technical operation of 
MDI-DE.
