IDRISI ascii format import

Hi

I finally found a tool to convert e00 format ARC/INFO files to
something more usable (ECV2000 tool. Runs only on Win through :frowning:

Now, how do I get the info from the resulting IDRISI .dvc and .vec into
Grass? I read that IDRISI binary .img files can be used directly, but what
about these ascii files?

There is a v.out.idrisi module that will produce exactly the same format
(.dvc & .vec) in an idrisi directory of the current mapset. But there is
no corresponding v.in.idrisi.

So there must be a simple solution, only I haven't found it. So I ask.

I have a m.in.e00 program that import e00 files into Grass. I sent
a pre-release to Markus, but have now something more useable (i.e.
understand arc, point, polygone and grid coverage). There is still
some work to do, but you get the lines and some cats files for
attributes. I wanted to post this version today, but forgot the
files at home (and can only post at work :-().

I hope to sent the stuff tomorrow, probably with an improved manual.

Hi there,

I am interested in obtaining the tool you mentioned, that is to convert arc info
.e00 format in to Grass format. Hope youcan send me the tools that you
mentioned.

Thanks in advance for your cooperation.

Without Idrisi or some other program which can read and convert Idrisi
files into something else which Grass can use you might have to learn about
the format of ascii Idrisi .vec files and reformat them. The other option
is to get the documentation for .e00 files (Arc export files) which is not
easy to find and then write your own conversion program.
