Service Description
This dataset is the new version of the Effective Mesh Density (seff) 2016 dataset with improved input data, for the year 2009. This new dataset uses the Copernicus Imperviousness and the TomTom TeleAtlas datasets as fragmenting geometries. The Effective Mesh Density (seff) is a measure of the degree to which movement between different parts of the landscape is interrupted by a Fragmentation Geometry (FG). FGs are defined as the presence of impervious surfaces and traffic infrastructure, including medium sized roads. The more FGs fragment the landscape, the higher the effective mesh density hence the higher the fragmentation. The geographic coverage of the dataset is EEA39.

Service Description
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 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 cell size regular grids as reporting units. Please note that the size of the reporting unit does not have an effect on the indicator. The index Effective Mesh Density (seff) is a measure of landscape fragmentation, i.e. the degree to which movement between different parts of the landscape is interrupted by FGs. The seff value is calculated as 1000/meff, hence number of meshes per 1000 km2.
