I am trying to read in the USGS DLG (1:100K), but am having trouble.
What is the trick?
I downloaded the optional format files, uncompressed them into the
appropriate dlg directory, and ran v.in.dlg. The program begins to
read the file but reports the following:
ERROR: Number of sides in the polygon defining the coverage
of the map less than 4.
25400000000D+01 4 0 4 1 -0.106007030000000D+09 0.3202203
Another words the Dlg header is incorrect.
Dlg header line 4, data element 8.
Is there another procedure? Do the files need translating somehow
first? Can I use the SDTS formats instead?
Thanks for your help.
