This 3D anaglyph movie of Hawaii Island was generated by 3dem and is based on USGS DEM data downloaded from geoarchive.net It dramatically shows the difference between the massive and smooth Mauna Loa and the more compact although taller Mauna Kea. The notched area in the north is the Waipio Valley. This movie is particularly stunning if you have red-blue anaglyph glasses. 1.4 megs movie
