The indicator is based on the method of Effective Mesh Size (meff, Jaeger 2000). The effective mesh size (meff) can be interpreted as the area that is accessible when starting a movement at a randomly chosen point inside a landscape without encountering a physical barrier (hereafter a Fragmentation Geometry). Meff<\/SPAN>expresses the probability that any two points chosen randomly in an area are connected; that is, not separated by Fragmentation Geometries (FGs) such as transport routes or built-up areas. Hence Meff is a measure of landscape connectivity, i.e. the degree to which movements between different parts of the landscape is possible. Meff is measured as an area (km2), within 1km2<\/SPAN>cell size regular grid as reporting units. Please note that the size of the reporting unit does not have an effect on the indicator. <\/SPAN>For a detailed methodology, please consult the indicator fact sheet.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "mapName": "Major anthropogenic fragmentation - effective mesh size", "description": "
