Reporting of assessment areas in 2012 Grid assessment areas an option for the 2012 reporting of geographical areas (see http://icm.eionet.europa.eu/schemas/dir200856ec/resources) INSPIRE compatible grid EEA reference grid recommended https://www.eea.europa.eu/data-and-maps/data/eea-reference-grids-2 EEA reference grid European Terrestrial Reference System 1989 (ETRS89) Lambert Azimuthal Equal Area projection (LAEA) Origin: 52°N and 10°E False northing 3 210 000 m. and false easting 4 321 000 m. Recommended grid resolutions 100 m, 1 km, 10 km and 100 km Standard grid cell naming e.g 100kmE31N36
EEA reference 100 km grid example

Spatial unit transformation - grid examples Maximum area Proportional Cell value = Σ ( Vi * Sharei ) Where: Vi = Value of unit i Sharei = Share of unit i within the cell In the example: V1 * 0.85 + V2 * 0.15 Point to grid E.g.
