Hello Everyone,

I was wondering if anyone had some insight for me. First are the facts:

30m DEM is availible from USGS for the United States
90m DEM is availible from USGS internationally
GLS LandSat data has 7 Bands and typically it does not include DEM

I have downloaded GLS2005 Imagery from USGS for an area in Peru, Lucky for me there was also a 30 Meter DEM included with a few of the tiles. Unfortunately there is no metadata for this DEM. Has anyone ever come across 30m DEM that is included with thier landsat data?

I have contacted USGS and they dont have any answers for me. I would love to gain access to 30m Dem for other parts of Peru and the world. Why would this 30m DEM be included in my landsat?
Anyone have any insight?

Thanks!

A near global 30m DEM is available, start here:

http://asterweb.jpl.nasa.gov/gdem.asp

NASA describe it as "research grade" so be aware that there are anomalies within.

Or the japanese site for ASTER GDEMs, which I find easier to use:

Better a late reply than never...

How sure are you that the DEM is a DEM? Are you assuming it is a DEM from the filename, filetype or the bit-depth of the data?

If the latter, it may be an array of scene radiance or reflectance values for a spectral band or perhaps of the values for a spectral band(s) ratio, may be NVDI.
