Description
Average degree of fragmentation of the country expressed by effective mesh size (meff) in square kilometres (km²) and proportion of uncut spaces over 100 km² and over 50 km² as a percentage of the country’s area. The effective mesh size refers to the probability that two points (e.g. animals) are not separated by obstacles (e.g. settlements, roads). The more obstacles there are, the smaller the probability of two animals being able to meet, the smaller the effective mesh size becomes.
Intersection geometries:
Route and area infrastructure data of the Official Topographical Cartographic Information System (ATKIS DLM25) with the separating objects roads (federal highways, federal, state, district and municipal roads), rails, rivers from a width of 6 m, lakes and settlements.
Existence of a time series with the data points 1930, 1966, 1977, 1989, 1998, 2004 and 2013. Calculation of the effective mesh size and the UDR greater than 100 km² and 50 km² respectively.
Updates are foreseen.
