We have been using the SDTS-DXF conversion program by Sol Katz version
.003 to convert 1:24K DLG files for use in CAD and ultimately for
importing into ArcView. I have a hypsography file here now that will
not convert for some reason.
I keep getting the message "error reading data record subfield". I have
converted hundreds of these files with this same DOS program in the past
but this particular file is acting up for some reason. Interestingly, it
does go ahead and convert partially. I can import the resulting dxf
file into AV but there is quite a bit of contour data missing. The .dxf
file won't open in any of the CAD software we use.
At first, I thought the USGS file was corrupted; however, I downloaded
it from another source and have the same results. Either the same file
is corrupted on separate servers or there is something unique about this
Can anyone recommend another SDTS-DXF converter? I'm at a bit of a loss
as to what to try next? I really need this hypsography layer to
complete a map I'm creating. As always, any advice will be greatly
Thanks in advance.
