2. Distribution maps The issue Extreme heterogeneity of spatial data
31 projections / 25 MS
Points (locations or centroids), multipoints, polylines, polygons
ca. 8 months person-days used to ‘harmonise’ data
‘European picture’ often blurred
Additional difficulty in analysing and interpreting distribution data

3. Distribution maps The proposal Standard submission by all MS
MS to convert available distribution data
Feature type: polygon = filled 10km ETRS grid cells
