I think Paolo has a point there. -32768 means "no data". So the "correct" way to get the coastlines would be vector data. However I think the other solutions will work in most parts of the world since: "The dataset available online has been cut for shorelines using the Shorelines and Water Bodies dataset (SWBD) that accompanies SRTM topography data." (quote from http://srtm.csi.cgiar.org/SRTM_FAQ.asp ) Whatever solution you choose, there might be other areas of the world with -32768 that are no ocean. How accurate is the SWBD used to clip the DEM? Just thinking aloud. ;-) ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ Xcsoar-user mailing list Xcsoar-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/xcsoar-user
