Hi guys, Exciting map geek news! Version 2 of the ASTER GDEM data[1] has just been officially released for civilian use![2]
Some of you may have been aware of the ASTER GDEM map data that was released back in 2009 (Version 1). This data contains the 3D elevation of 99% of the earth at a resolution of 30 meters. This is 9 times more dense than the SRTM3 data (90m resolution) that is the default data used in Google Earth. However, version 1 was only released as raw data only fit for scientific research. In version 2, they have clean the data and it can now be used by the general public. :) I once played with GTOPO30 and SRTM3 data to create topographic maps[3] and I think the ASTER data would be interesting to play around with. :) [1] http://www.gdem.aster.ersdac.or.jp/ [2] http://www.wired.co.uk/news/archive/2011-10/19/nasa-elevation-map [3] http://vaes9.codedgraphic.com/posts/topomaps_using_srtm3_data
