[GRASS-user] GRASS GIS meetup in Raleigh, North Carolina, Nov 5

[Vaclav Petras]

Dear all,

next GRASS GIS Raleigh meetup is November 5. We had meetup almost every
month since December 2015. If you are or know people from the area, help us
spread the word for this one by tweets, personal emails, or whatever feels
appropriate to you. If not, then get inspired and organize one yourself.
See full announcement at the bottom of the email.

Best regards,
Vaclav


GRASS GIS Raleigh meetup, November 5, Hunt at NC State

Interested in using GRASS GIS as a geospatial processing backend? Or for
reproducible research with Python? Or as a surprisingly powerful desktop
GIS? Then come to the November GRASS GIS Raleigh meetup which will be
specifically focused on getting newcomers started with anything ranging
from using GRASS GIS to programing and contributing. The meetup is planned
for Saturday, November 5. Meet in 4502 Fishbowl at the Hunt library at NC
State Centennial Campus at 2 PM. Join any time during the afternoon; we
will be there at least till 6 PM, but there is an option to stay longer.

Contact Vaclav Petras (Vashek) if you have any questions:

In earlier versions the default colour table was 'rainbow'."


Paulo,

  If a user notices shifts in color from what modules in prior versions
produced is it likely for them to think of looking at r.color if they don't
explicitly use that module?

  Writing only for myself, I would not have thought of looking there as I
focused on the modeling required for my current project.

  A better location would be the download page, at the top, in a single file
that maintains a running history of changes.

Regards,

Rich

Markus,

  Perhaps a running CHANGELOG on the download page of the wes site would
help. In there major changes, by release (including development releases)
would be recorded.

  The CHANGELOG could include addition of new features, significant changes
in existing features, file storage structure changes, major updates to
modules, and other information of value to users.

   - viridis color table is the new default replacing rainbow (manage
with G7:r.colors)
Just running i.pca and noticed that the output layers are not (all) 
colored using the viridis color table. In the example on the help page, 
the colors of the layers are grey scale. Does the i.pca module apply a 
color scheme explicitly, or how does this work?


Markus,

   I should have checked before writing. My apologies to all.

Rich,

no problem and nothing to apologize for.
