Hi all!<br>
I'm Roberta Fagandini, Ph.D. student at Politecnico of Milano.<br>
My proposal "GRASS GIS module for Sentinel-2 cloud and shadow<br>
detection" has been accepted therefore I've been selected for<br>
the GSoC 2018.<br>
I'm glad to start contributing to OSGeo and especially to GRASS<br>
GIS with the help of my mentors Roberto Marzocchi and Moritz<br>
Lennert.<br>
<br>
My project consists in the realization of a GRASS GIS module for<br>
the detection of clouds and their shadows in Sentinel-2 images<br>
without using time series.<br>
Below you can find the link to my proposal:<br>

<br>
I would be grateful if you could have a look at the proposal and<br>
provide any suggestions.<br>
Every feedback is welcome and it will be useful to improve my<br>
project.<br>
<br>
I'm waiting for the writing access to the OSGeo wiki, therefore,<br>
I will share my wiky page as soon as possible.<br>
<br>
Thanks for this great opportunity!<br>
<br>
<br>
It is great to have you with us ! I'm looking forward to working<br>
with you on this project.<br>
<br>
<br>
First of all I want to thank you for being my mentor!<br>
<br>
The first thing I would love to see is your existing python script<br>
to get a better understanding of the exact approach you are planning<br>
on implementing.<br>
<br>
<br>
Depending on what tool you prefer, you can either set up a github<br>
repository for the project, or you could also use the sandbox in the<br>
GRASS svn [1]. You could then share your code there.<br>
<br>
<br>
A the moment I have only some bash script. I'm testing different procedures for shadows detection, which is the task that is creating more troubles at the moment. Anyway, I already had the intention of setting up a github repository for the project therefore, I hope to share it as soon as possible.<br>
<br>

Please also set up a wiki page about your project. See [0] for examples from last year.<br></blockquote><div><br></div><div>Sure, tomorrow I'm going to set up the wiki page!</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Looking at your bash scripts, I think the first thing to do during this bonding period is, as you planned yourself, to get familiar with the writing of GRASS modules in Python. You can have a look at existing scripts [1, 2] to get feeling for this works and how to structure addon code in order to make it directly installable with g.extension.<br>
<br>
You can find the actual function definitions and documentation of the GRASS Python scripting library at [3]. The functions in that library should be more than enough to translate your scripts into a (or several) modules.<br>
<br>
Be aware that GRASS modules create their own GUI. So, unless you need some interactive features in your modules, you will not have to program your own GUI.<br></blockquote><div><br></div><div>Thank you for your precious suggestions! I'll start studying how to write a GRASS module in Python in the next days and at the same time I will keep on testing the procedures so as to show you some results and fix some open points.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
Something else you should probably do during this bonding time is to elaborate a schema of your algorithm, so that it is easier to understand what it does at each step.<br></blockquote><div><br></div><div>Yes, this could be very useful also for me in order to better organize and put in order everything!</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
