This raster dataset represents landscape fragmentation across EEA38 plus the United Kingdom in 201<\/span>5<\/span> using normalised effective mesh size (meff) at 1 km resolution.<\/span><\/p>

<\/p>

The indicator was calculated using the cutting-out procedure within the EEA 1 km reference grid. The fragmentation geometry was derived from two principal input datasets: transportation infrastructure, including selected road classes and railways, from the <\/span>commercial <\/span>TomTom MultiNet vector dataset provided by Eurostat; and built-up surfaces derived from the harmonised 100 m Imperviousness Density (IMD) dataset produced within the Copernicus Land Monitoring Service. An imperviousness threshold of 30% was applied to identify built-up areas, while roads were buffered according to their functional class.<\/span><\/p>

<\/p>

The normalised meff value expresses the probability that two randomly selected points within a reporting unit belong to the same unfragmented landscape patch. Values range from 0 to 1, where values close to 0 indicate very high landscape fragmentation and low connectivity, while values close to 1 indicate a largely unfragmented and highly connected landscape.<\/span><\/p><\/div><\/div><\/div>", "mapName": "Map", "description": "This raster dataset represents landscape fragmentation across EEA38 plus the United Kingdom in 2015 using normalised effective mesh size (meff) at 1 km resolution.The indicator was calculated using the cutting-out procedure within the EEA 1 km reference grid.
