EC contribution Overarching objectives  data gap analysis  spatially explicit regional scenarios of development  develop early warning and decision support tools at regional, national and local levels  Build capacities in the Black Sea region to enhance data interoperability, by promoting open standards (ISO and OGC)  large scale, high resolution distributed hydrologic model of the Black Sea watershed  a Grid-enabled Spatial Data Infrastructure (SDI)
