Dissection of the countryside 1935–2002: average size of a non-dissected area in km2

Definitions/Comments: territories below 2100m. The geometry of dissection is based on the criteria of possible settlement, i.e. areas such as glaciers and lakes have been excluded. The following are considered as barriers or elements of dissection: motorways, roads (classes 1–3), tracks, settlements, rivers, lakes and mountains (territories above 2100m).
