DEGREE OF URBANIZATION: for countries with CORINE LC the followed methodology was: crossing of clc90 with a regular grid of 10 km in order to compute an indicator showing the % of artificial surfaces for each grid cell. The % of artificial surface was then reclassified into 3 categories: low (0-25%), moderate (25-50%) and high (50-100%). The crossing & generalization of coastline in base the artificialisation layer was done by manual digitalisation. Countries without CORINE LC coverage the coastline was digitized using different analog sources.OIL SPILLS and WATER POLLUTION: features were digitized from different analog sources.
