The Nationally designated areas inventory was formerly known as the Common Database on Designated Areas (CDDA). The Nationally designated areas data is delivered by each country as spatial information (Type 1) and thematic information (Type 2). The inventory began in 1995 under the CORINE programme of the European Commission. It is an agreed annual Eionet core data flow maintained by the European Environment Agency (EEA) with support from the European Topic Centre on Digital Integration (ETC DI). The dataset is used by the EEA and e.g. the UNEP-WCMC for their main European and global assessments, products and services. The dataset is the official source of protected area information from the 38 European countries to the World Database of Protected Areas (WDPA). Nationally designated areas data can be queried online in the European Nature Information System (EUNIS).
