Parent Layer: Landscape Fragmentation MEFF

Name: Effective Mesh Size

Display Field:

Type: Raster Layer

Geometry Type: null

Description: The Gross Landscape Ecological Potential is based on surface measurements which don’t capture handicaps to wildlife resulting from barrier effect of land fragmentation by roads, railways and constructions. Fragmentation is a limiting factor of how this ecological potential can be utilized in relation to minimum size of territories as well as connectivity issues. The assessment of fragmentation is based on the Effective Mesh Size (MEFF) 'cross-boundary connections' (MEFF-CBC) methodology computed for 1km² grid. It uses TeleAtlas roads and railways and UMZ data as fragmenting factors. MEFF value can be interpreted as the expected size of the area that is accessible when starting a movement at a randomly chosen point inside the reporting unit (in our case 1km grid) without encountering a physical barrier. So the higher MEFF value the less fragmented area around.
