Do you mean the DTED topo data?? If so it was retired a while back and replaced with SRTM data.. For the US take a look here <a href="http://dds.cr.usgs.gov/srtm/version2_1/SRTM1/">http://dds.cr.usgs.gov/srtm/version2_1/SRTM1/</a> . The rest of us can get lower resolution data here <a href="http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/">http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/</a> .<br>

You may have luck at <a href="http://data.labins.org/2003/MappingData/DLG/dlg.cfm" target="_blank">http://data.labins.org/2003/MappingData/DLG/dlg.cfm</a><br>
<br>
FYI, I believe most states have a GIS (Geographic Information Systems) data clearinghouse of one sort or another, where all manner of maps can be had.<br>
<br>
Sometimes it works out better to go to your state's clearinghouse rather than direct to USGS.<br>
<br>
Good luck!<br>

Hi all,<br>
<br>
Years ago the USGS published a series of CD's containing their 1:100,000<br>
Digital Line Graph (Optional Format) map data. This could be utilized by APRS<br>
mapmakers to create detailed maps for the DOS version of APRS. I have copies<br>
of these disks for the northeast (which is where I'm from), and have made such<br>
maps for Long Island, New York City and portions of New Jersey. Unfortunately<br>
these disks are no longer available, and I'd like to try to make some maps for<br>
the Tampa area. Maybe more later, as well ... if I can locate a copy of that<br>
CD. Does anyone have one that can make a copy for me?<br>
<br>
Apparently, the data is supposed to be downloadable, but I haven't been<br>
able to do so. When you go to their website, it says you need to wait for the<br>
tape server to load ... which seems to take forever.<br>
<br>
Why do I want to make maps for a dinosaur version of APRS? Among other<br>
reasons, APRSDos will run on literally any PC clone from 8088's up, with 486's<br>
being the sweet spot for fast map loading. Any old laptop you have gathering<br>
dust can be set up at a shelter or EOC in a deployment and utilized for APRS,<br>
or other DOS-based packet programs.<br>
<br>
While many newer APRS clients have flashier maps, interesting bells-and-<br>
whistles and can interface with the internet, APRSDos has many features which<br>
no other client does.<br>
<br>
As the brainchild of Bob Bruninga WB4APR "The Father of APRS", it's true<br>
to his original concept of what APRS is about, namely that:<br>
<br>
"APRS is a real-time tactical digital communications protocol for exchanging<br>
information between a large number of stations covering a large local area."<br>
<br>
It seems that much of this original concept has been supplanted with the idea<br>
that APRS' most useful - and, to many, sole - feature is to track vehicles and<br>
other movable assets. There are so many users that have never used APRS with<br>
anything more than a self-contained box (Kenwood TM-D710, Yaesu FTM-350, Tiny-<br>
Track, etc) and have never connected one to a computer, and ran an APRS client<br>
on it to see some small part of what APRS is truly capable of!<br>
<br>
If, by creating some local maps, letting users dust off an old clunker so<br>
they can get a taste of how APRS can be utilized in tactical situations or in<br>
a disaster scenario, then it'll be more than worth it to me. And, I hope, the<br>
Emergency Management infrastructure would also see its value to their efforts.<br>
<br>
So if anyone has a copy of that 1:100K DLG disk, please contact me. 73<br>
