Derived from NASA's SRTM elevation data, the dataset is conditioned for drainage direction analysis, but is less reliable above 60 degrees north. It is accessible through Google Earth Engine using the snippet `ee.Image(\"WWF/HydroSHEDS/30CONDEM\")`. The hydrologically conditioned DEM (b1) has a 927.67-meter pixel size, with elevations ranging from -415 to 8247 meters. Data is free for both commercial and non-commercial use.\n"]]
