Thanks Oshyan. The terrain does have actual displacement, just an image map set to give a maximum displacement of 8848 meters (the height of Mount Everest). There is no displacement for below the ocean since I haven't gotten the bathymetry data to work properly. As a result, the water is just a reflective shader being controlled by a homemade water map to make sure the reflectivity doesn't extend onto the land. The clouds are actually two separate cloud layers (one with 500m height and the other a height of 2000m with altitudes of 2000m and 2500m respectively) both masked by the blue marble cloud map using the highest available resolution (43200 x 21600). All shaders have been adjusted for contrast, brightness, gamma, and saturation in photoshop to try and provide the most realism possible.
