SHORT DESCRIPTION
  •  Info created by NASA - uploaded by User:LuisArmandoRasteletti - nominated by User:LuisArmandoRasteletti -- LuisArmandoRasteletti (talk) 06:45, 15 May 2010 (UTC)[reply]
  •  Support -- LuisArmandoRasteletti (talk) 06:45, 15 May 2010 (UTC)[reply]
  •  Comment Needs a better description. What's a Global Digital Elevation Model? Jafeluv (talk) 09:49, 15 May 2010 (UTC)[reply]
    •  Comment It probably means that, under certain climatic circumstances in the future, people living in the blue areas are either dead, or breathing trough a scuba tank. --Alex:D (talk) 12:03, 15 May 2010 (UTC)[reply]
  •  Comment - Very little value as is. This is probably a hypsometric map of the world, where each colour corresponds to a class of elevation above mean sea level. But a proper scale is missing, as well as an indication of the map projection and some form of georeferencing (e.g. graduated meridians and parallels). Also there are areas not covered by the representation. -- Alvesgaspar (talk) 13:51, 15 May 2010 (UTC)[reply]

  •  Oppose I think we could feature this picture as an example of how to get a poor image out from a good database. How on Earth (no pun intended) did they manage to make central Russia look more mountainous than the Rocky Mountains? Also I love the transient between purple and green... And add to that the comments made by Alvesgaspar. One of the worst topographic images out there IMO. - Keta (talk) 15:17, 17 May 2010 (UTC)[reply]
  •  Info This Global Digital Elevation Model, or GDEM, is a product of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), a joint program of NASA and Japan's Ministry of Economy, Trade and Industry. The image was released on 29 June 2009, and was created by processing and stereo-correlating the 1.3 million-scene ASTER archive of optical images, covering Earth's land surface between 83 degrees North and 83 degrees South latitudes. The GDEM is produced with 29 m postings, and is formatted as 23,000 one-by-one-degree tiles. In this coloured version, low elevations are purple, medium elevations are greens and yellows, and high elevations are orange, red and white. With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 100 m, ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched 18 Dec. 1999, on NASA's Terra satellite. The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. --LuisArmandoRasteletti (talk) 23:30, 18 May 2010 (UTC)[reply]
