It is a framework for international research and development cooperation, allowing to coordinate national research at European level. COST does not fund research as such, but coordination of research. COST includes as member states countries from the European Union, and a number of other European countries. Daquamap Data Quality MAP DEM Digital Elevation Model. This is an interactive program that comes in very handy for GIS people and environmental scientists. USGS has made available on the Internet, 1-degree Digital Elevation Model (DEM) data for the entire United States. Determining exactly which DEM file covers the region of your interest can sometimes be cumbersome. DFG Deutsche Forschungsgemeinschaft DLR Deutsche Forschungsanstalt für Luft und Raumfahrt e.V.
