The biogeographical regions dataset contains the official delineations used in the Habitats Directive (92/43/EEC) and for the EMERALD Network set up under the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention). Changes in 2016 version: The Pannonian region of Serbia was missing in previous versions and this has been corrected in the 2016 version. Some Arctic islands which do not belong to the European part of Russia and which were erroneously included in previous versions have been removed. Biogeographical boundaries were obtained from the EU Member States and from the Emerald Network countries. These were merged together to produce a European wide map of the biogeographical regions independent of political boundaries. A number of the regions were updated during the work under Article 17 of the Habitats Directive (92/43/EEC) and in 2010 the Standing Committee to the Bern Convention adopted a number of changes according to progress in the setting-up of the Emerald Network. http://www.eea.europa.eu/data-and-maps/data/biogeographical-regions-europe-3

Dataset contains data selected from reporting of member and collaborating countries on Ammonium, Nitrate and Nitrite concentrations in groundwater sites. Reported data have been assessed and processed by the ETC-Water and the EEA. Disaggregated records were annually aggregated and statistic value calculated.

The Urban Atlas is part of the implementation of the Global Monitoring of Environment and Security (GMES) service. Compiled from thousands of satellite photographs, the Urban Atlas provides detailed and cost-effective digital mapping. The Urban Atlas will enable urban planners and the public to assess risks and opportunities, ranging from threat of flooding and impact of climate change, and to identifying new infrastructure needs. All cities in the EU will be covered by the Urban Atlas by 2011. This map will provide for the first time homogeneous and up-to-date information on urban environments, allowing for a comparison of different cities all across Europe.
