Methodology for obtaining data Data formats:
EEA is able to use GIS digital data in most standard mapping formats. ArcInfo export format and ArcView shape files are ideal, but Mapinfo interchange files or dxf files are also acceptable when sufficiently described.

Different data structures may exist in different countries for geographical layers and attribute tables. Whatever format is used, it should be possible to extract from the delivered GIS data, separate layers for each of the designation types in "Designation" table and individual points, lines or polygons should refer to at least one of the CDDA site codes as indicated in the "Sites" table.

If one site is designated under several designations it might be present in different GIS layers. In such cases, attention should be given that exactly the same boundary is present in the different layers.
