> Now, NASA/METI has released the 30m global (83°N and 83°S and is
> composed of 22,600 1°-by-1° tiles) ASTER GDEM based on 1,264,118
> single ASTER dems from 1.4 million scenes in total. 95% vertical ci:
> 20 meters, 95% horizontal ci: 30 meters)

> ASTER GDEM is an easy-to-use, highly accurate DEM covering all the
> land on earth, and available to all users regardless of size or
> location of their target areas. Anyone can easily use the ASTER GDEM
> to display a bird's-eye-view map or run a flight simulation, and this
> should realize visually sophisticated maps. By utilizing the ASTER
> GDEM as a platform, institutions specialized in disaster monitoring,
> hydrology, energy, environmental monitoring etc. can perform more
> advanced analysis...

> ASTER GDEM tiles can be downloaded electronically from ERSDAC by
> visiting the link below: This web-based search system has 4 methods
> for tile selection. You can select tiles with one of the following
> methods.

> 1. Select tiles directly
> 2. Select tiles by polygon
> 3. Select tiles by shapefile
> 4. Select tiles by coordinates
