That's really good for you to familiarize with writing code in GRASS, as
that would give your idea more chances.

No, that is not necessary

Actually it works the other way around, you're supposed to write and submit
your proposal at this stage, so that potential mentors can comment on it
and give you feedback, and decide whether it's feasible and if they want to
mentor it. Please, follow the guidelines I linked to you to submit a
proposal, and share it publicly also in GRASS mailing list for developers
to comment.

Good luck!

Hi Margherita,

I really appreciate for your feedback! I'm not much familiar with GRASS GIS
as I had only developed standalone codes in Python using directly libraries
like GDAL and RIOS  and used QGIS for layers
visualization. But, as I observed here
 and here
, Python scripts can
easily be integrated within GRASS GIS and I could seamlessly adapt my
programming skills to work with that. That way, I could compromise myself
in integrating my already done codes (and new ones) into GRASS GIS
software/libraries.

Also, if allowed, I could edit the Ideas' wiki page to contemplate my own
idea, so that it could be visible to a broader audience. If I get a mentor
in time, I will make a detailed proposal for the mentors/community be able
to understand better the idea.

Thank you very much,

Evandro Carrijo Taquary

Hi Evandro,

thank you for your proposal, I put in cc also the GRASS GIS dev mailing
list, as it might be a suitable project candidate if anyone is available
for mentoring it. It is usually a bit more difficult to find mentors when
the proposal comes from a student and it is not listed in our ideas page,
however not impossible, and your idea sounds very interesting. Are you
familiar with GRASS GIS?
I'd like to point you out our recommendations for students at
https://wiki.osgeo.org/index.php?title=Google_Summer_of_Code_Recommendations_for_Students
, particularly our guidelines on how to submit a proposal.

Thanks,
