January 2002--MapMart.com, IntraSearch's (Englewood, Colorado) online initiative is the second commercial vendor to partner with the USGS to distribute free 7.5' SDTS DEMs on the Internet. MapMart is an online resource for the location and acquisition of a variety of digital map data. MapMart also sells numerous digital data products. The ordering of digital data can be done at different map scales, and in various mapping software formats.
August 2001--The GIS Data Depot, our first online partner, provides free 7.5' SDTS DEMs online. The GIS Data Depot houses data in support of the GIS industry. SDTS DEM data and a variety of other digital data are also available for purchase via premium (fast) download and on CD-ROM from the GIS Data Depot.
If you experience problems ingesting the new FGDC-compliant data (available October 2, 2001), please contact your software vendor to find the latest information about software upgrades or patches. Users who rely on free or public domain software might check the Web discussion lists for the latest solutions. However, if you believe there is an error in the USGS data, please send email to the SDTS mailing list at sdts@usgs.gov.
Our partners will continue to receive SDTS versions of the DEMs as they are made available by the USGS. Native format DEMs are still available for sale from USGS on various media and via FTP.
Agreements with our partners to serve updated, SDTS DEMs for no charge are not exclusive agreements. If this is your interest, please see the information about the USGS Business Partner Program.
If you have additional questions or comments, please contact us at sdts@usgs.gov. Please monitor the SDTS Home Page for further news and updates on this issue. USGS SDTS web site.
The compliant USGS SDTS DEMs are available from the GIS Data Depot (October 2, 2001) and at MapMart.com (January 4, 2002) and ATDI (March 8, 2002).
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.
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.
