Message from USGS regarding SDTS DEMs
(Oct 14, 2001) -- New FGDC-Compliant USGS SDTS 7.5' DEMs available on-line. A Non-compliant
profile identifier was used in the USGS SDTS DEMs that were released to the
public at the GeoCommunity GIS Data Depot in July 2001. The compliant USGS
SDTS DEMs are now available from the GIS Data Depot
(http://www.gisdatadepot.com). Non-compliant data have been purged and are
no longer being distributed. The issue of non-compliance was with the
profile identifier name only and did not affect the integrity of the data.
You will also notice a change in the naming convention regarding the
FGDC-compliant dataset and the tar file. For example, the Dixon, Missouri
quad's .tar file name is 1626663 (preceded by GeoComm's unique download
instance identifier) and the .ddf names are 7364. This change is the result
of USGS maintenance requirements and does not affect the data. For more
information, please see this notice: New FGDC-Compliant SDTS 7.5' DEMs
available at GeoCommunity site
(http://mcmcweb.er.usgs.gov/sdts/geocomm.html).
Please note that the GIS Data Depot is not responsible for the
non-compliant identifier name. The USGS is the maintenance authority for
SDTS and continues to be the technical contact for the data and is
responsible for policy regarding data distribution. Please email us at
sdts@usgs.gov for more information.
