[gdal-dev] ogr2ogr: debugging slow performance when converting .e00 to other formats

[Mike Flannigan]

I would try the "Geo::E00" module for Perl.
If you can get the file to me, I'll try it
for you.  Or you can install Perl and try it
yourself.

I just checked my files, and surprisingly I have
no E00 files.  I guess I just convert them and throw
them away, because I remember converting quite a few
in the past.  I also remember that the module does
not work on every E00 file, or at least does not
produce what I expect to see.

The "Geo::E00" module at Perl just produces a text file,
which is what I normally want.

Another option is to use QGIS to convert it.
That may be the best option for you.


Mike

After several hours the conversion operation is still running, but the files only grow very, very slowly.
