Welcome to the NUMIS portal, the environmental information portal run by the German Federal State of Lower Saxony! NUMIS offers a one-stop entry point to environmental information held by Lower Saxonies governmental organisations and institutions: web content, databases, topic pages, measurements, events, publications, maps and more.

The NUMIS search engine is the central component enabling a simple, fast and comfortable keyword search on all content indexed by our spider. With the Advanced Search you can specify more specific queries, for instance supported by a thesaurus, a gazetteer and a map client.

By means of the NUMIS portal, the federal state faces up to the challenges arising from Lower Saxonies Environmental Information Directive. (Niedersächsisches Umweltinformationsgesetzes, NUIG). The NUIG is Lower Saxonies implementation of the Directive 2003/4/EC on public access to environmental information of the European Parliament and of the Council of 28 January 2003. More information on the legal background can be found at the bottom of this page.

The NUMIS portal is operated by Lower Saxonies Ministry of Environment and Climate Protection. We are continuously trying to enhance and optimise our systems. If you have questions or suggestions, do not hesitate to contact us: Environmental Information Systems Working Group, Lower Saxony Ministry of Environment and Climate Protection.

Legal conditions I: Directive 2003/4/EC on public access to environmental information of the European Parliament and of the Council of 28 January 2003.

The directive considerably extends the right of European citizens to free access to environmental data and information and re-defines the terms of trade for environmental information in both an organizational and a technical sense:

The directive extends the circle of organizations that are required to publish environmental information. Not only environment agencies on the higher administrative levels, but all administrative organizations on all levels of the hierarchy have to make environmentally relevant information available. In addition, all private companies and semi-private organizations that fulfill environmentally relevant public obligations are included as well.

The directive explicitly calls for active distribution of data and information. Thus, not only references to data and information (i.e. metadata), but in many cases the data and information objects themselves should be online.

Legal conditions II: Directive 2003/98/EC on the re-use of public sector information of the European Parliament and of the Council of 17 November 2003

The PSI-Directive is built around two key pillars of the internal market: transparency and fair competition. It sets minimum rules for the re-use of PSI throughout the European Union. In its recitals it encourages Member States to go beyond these minimum rules and to adopt open data policies, allowing a broad use of documents held by public sector bodies.

While the main focus of the Environmental Information Directive is transparency between public authorities and citizens, the PSI-Directive deals with the way public sector bodies should enhance the re-use of their information resources in order to enhance their role as part of the general economic value creation chain. Even if the target audience of this Directive is not the citizen, many concrete actions, particularly in the field of geographic information, match with the implementation of the Environmental Information Directive.

Legal conditions III: Directive 2007/2/EC establishing an Infrastructure for Spatial Information in the European Community (INSPIRE) of the European Parliament and of the Council of 14 March 2007

The INSPIRE directive came into force on 15 May 2007 and will be implemented in various stages, with full implementation required by 2019. It aims to create a European Union (EU) spatial data infrastructure. This will enable the sharing of environmental spatial information among public sector organisations and better facilitate public access to spatial information across Europe.

A European Spatial Data Infrastructure will assist in policy-making across boundaries. Therefore the spatial information considered under the directive is extensive and includes a great variety of topical and technical themes.

The NUMIS portal delivers metadata and map services to the INSPIRE data infrstructure.
