If 3.2 can't import the data accurately to begin with - viola - garbage in,
garbage out!
For the .E00 files I have when 3.2 reads the coverage created by IMPORT or
IMPORT71 it fails to make line or point layers. And the polygons it makes
do not match those displayed by ArcExplorer 2.
ArcExplorer 2 can create line and area (but not points) from the product of
IMPORT and IMPORt71, but of course all you can do is look at the result.
IMPORT and IMPORT71 are very low quality tools if they are suppose to
convert .E00 to anything useful by either ESRI or any other GIS tool IMHO.
You should probably temper your suggestions to others to use IMPORT and
IMPORT71 with a caveat that they cannot convert all .E00 files, which they
provable cannot. And can't convert 100% of the files they seem to convert
with no error messages.
I don't blame ESRI for not supporting free conversion of .E00 to a more
public transfer standard. Why would they want to help people using tools
other than ESRI?
I've also received some supposed SDTS output from ArcInfo users (federal
agency) and it was garbage. I have no idea if the output was created by
ESRI code or by some frustrated user that had to get some information into
the hands of the public and ESRI wasn't supporting him or her so they rolled
their own.
I'll also ask you to join me in flaming any site that publishes public
domain data in a proprietary format - .E00.
These agencies should not be lead to believe by GIS experts that .E00 is a
public interchange format, it is not. As far as I can tell it is a way to
move files from one system to another using the same
make/model/version/extension of _ESRI_ software and nothing else.
