Hi Moritz and Roberto!
Here [0] you can find the schema of the algorithm!
I committed [1] the first results of the procedure. In this case, I used the image S2A_MSIL1C_20171025T095101_N0206_R079_T33SVB_20171025T134153 (Sicily). I have already tested the procedure using other two or three images but I want to keep on testing!
If you have any suggestions about the testing phase please let me know! As I wrote in another mail, I have the intention of trying out the procedure using several images sensed in different seasons, latitude, etc.
Best wishes
Roberta

Nice! The last step of the script you have written in python works as you expected.
Now it is important to draw a diagram (or schema ) as a summary for you (you have worked a lot in the last few months) and to share it with Moritz and Markus.
After that, test, test and test
for validation/calibration of the automatic procedure.

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.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.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.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.
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.Yes, this could be very useful also for me in order to better organize and put in order everything!
Have you advanced on any of this ? Do you have any questions ? Please don’t hesitate to ask on the mailing list.
Yes, I started working with GRASS Python scripting library. I’m following the link [0] you suggested, I’m also looking at other existing GRASS scripts [1,2] and moreover, Roberto gave me one of his scripts as an example. I have just committed the first version of the python script I’m working on, it works and I’m quite satisfied
Tomorrow I want to elaborate the schema of the algorithm and at the same time, I have to keep testing the procedure. As I wrote in the bash file, shadows detection seems to be strongly land cover dependent therefore I think it is necessary to test the procedure using several images sensed in different seasons, latitude, etc.
Anyway, I’ll commit some results tomorrow so as to show you something more concrete!
Best wishes,
Moritz
