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

[Eugene Alvin Villar]

Interesting. It's kinda expected that it will have poor data in places
with skyscrapers. I don't think remote sensing is currently
sophisticated enough to distinguish buildings from surrounding
features.

But, basing on your visualizations, it *seems* that ASTER data has a
higher resolution than SRTM. Have you compared in non-urban areas with
dramatic changes in slope such as the Wawa Dam area? :)
