EarthObserver as iPhone App

Columbia University recently published yet another earth science application for Apple's iPhone. The app is called EarthObserver and is available from Apple's iTunes store. EarthObserver provides

• Basemap (computer-generated color-shaded relief of land and ocean floor)
• US Coastal Bathymetry (with color palette appropriate to provide details of bays, sounds, estuaries, harbors and rivers)
• US Nautical Charts (paper raster and digital electronic at all scales for Atlantic, Pacific, Gulf of Mexico, Bering Sea, Arctic and Great Lakes)
• US Topographic Sheets (entire USGS collection for US mainland, Alaska, Hawaii and Puerto Rico)
• Geologic Maps (entire world, by continent, by country and by US state showing formation ages, names and rock types)
• Geophysical Maps (global earthquakes, tectonic plates and boundaries, gravity anomalies, geoid height, magnetic anomalies and the configuration of world stress)
• Land Surface (temperatures day and night, primary productivity, vegetation index, land cover classifications and diversity, forest cover types and fragmentation)
• NASA Visible Earth (global earth scenes for each month)

And many more. See EarthObserver's homepage for more information.
