ASTER HDF Georeferencing Off by 1KM?

Description (last modified by )
Andrey,
Steve Soule from Vexcel has pointed me to an ASTER HDF file which seems to have incorrect georeferencing. He raised the concern because the georeferencing didn't match a GeoTIFF file derived from the file by other software.
I confirmed this, and noticed that the lat/long corners of the image as reported in the metadata don't seem to match the lat/long corners reported after reprojection (in the gdalinfo report).
I will attach the gdalinfo report to this bug report. The file itself is pretty large so I am putting it putting it at the following url for download, assuming you need to do that.

By the way, Steve reports the GeoTIFF file derived from the HDF file was generated with a program called HEG_Win, though the file itself reports it was generated with Erdas Imagine. However, hopefully you will be able to establish from the Aster file itself whether there is an inconsistency.

Frank, Whether it is possible to see gdalinfo report for mentioned GeoTIFF file? In fact I'm aware of problems with ASTER DEM georeferencing and I thought that I did my best to get it working. It is good news that there is a tool that works better. The only question remains: how those tool works :-)

Andrey, The GeoTIFF files gdalinfo report looked like this: Driver: GTiff/GeoTIFF Size is 2507, 2402 Coordinate System is `' Origin = (-116.929440,34.986245) Pixel Size = (0.000287,-0.000238) Metadata: TIFFTAG_SOFTWARE=IMAGINE TIFF Support Copyright 1991 - 1999 by ERDAS, Inc.

However, this isn't likely to help you much as the TIFF file had been resampled and reprojected.

The sample file is behind a dead link and without it (or some other ASTER HDF file leading to similar troubles) it feels unnecessary to keep this ticket open forever.

Ticket is pretty old with no activity in recent years. ASTER data is nowadays available as GeoTIFFs and there it a HEG conversion tool http://newsroom.gsfc.nasa.gov/sdptoolkit/HEG/HEGDownload.html. Enough reasons for closing this issue.
gdalinfo report for file.
