Normalised effective mesh size (meff) representing landscape fragmentation across EEA38 plus the United Kingdom in 2018 at 1 km resolution, calculated using the cutting-out procedure. Values range from 0 to 1, where lower values indicate higher landscape fragmentation and lower connectivity, while higher values indicate greater landscape connectivity. |

<div style='text-align:Left;font-size:12pt'><div><div><p><span>This raster dataset represents landscape fragmentation across EEA38 plus the United Kingdom in 2018 using normalised effective mesh size (meff) at 1 km resolution.</span></p><p><span /></p><p><span>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><span>commercial </span><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><span /></p><p><span>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> |
