[GRASS-user] Status of ITZI in GRASS?

Thu Sep 5 12:49:34 PDT 2024

Hi Venka,

I finally got time to run through your procedure -- thank you so much for
this! But, if I understand correctly, this only works within a docker
environment; is this correct?

I was able to successfully get through Step (d). However, the GRASS GUI
never launched and the process you provided installed GRASS 8.4, again,
within the docker environment. I was unable to work through the ITZI
tutorial due to these issues. I don't think this is a workable solution for
me. But, thank you!

Regards,
Tom
