[talk-ph] ASTER GDEM is now released for civilian use!

[Eugene Alvin Villar]

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. :)
