[GRASS-dev] GSoC introduction Roberta Fagandini

Roberta_Fagandini · April 24, 2018, 11:01am

Hi all!
I’m Roberta Fagandini, Ph.D. student at Politecnico of Milano.
My proposal “GRASS GIS module for Sentinel-2 cloud and shadow detection” has been accepted therefore I’ve been selected for the GSoC 2018.
I’m glad to start contributing to OSGeo and especially to GRASS GIS with the help of my mentors Roberto Marzocchi and Moritz Lennert.

My project consists in the realization of a GRASS GIS module for the detection of clouds and their shadows in Sentinel-2 images without using time series.
Below you can find the link to my proposal:

https://docs.google.com/document/d/1mQyouqbHGHugn5DjEDZI3hc1eU_bT_b0qLJPPwkt_hk/edit?usp=sharing

I would be grateful if you could have a look at the proposal and provide any suggestions.
Every feedback is welcome and it will be useful to improve my project.

I’m waiting for the writing access to the OSGeo wiki, therefore, I will share my wiky page as soon as possible.

Thanks for this great opportunity!

It is great to have you with us ! I'm looking forward to working with you on this project.

The first thing I would love to see is your existing python script to get a better understanding of the exact approach you are planning on implementing.

Depending on what tool you prefer, you can either set up a github repository for the project, or you could also use the sandbox in the GRASS svn [1]. You could then share your code there.

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

Please also set up a wiki page about your project. See [0] for examples from last year.

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.

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.

Moritz

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!

Thanks again!

<https://docs.google.com/document/d/1mQyouqbHGHugn5DjEDZI3hc1eU_bT_b0qLJPPwkt_hk/edit?usp=sharing>

I would be grateful if you could have a look at the proposal and
provide any suggestions.
Every feedback is welcome and it will be useful to improve my
project.

I’m waiting for the writing access to the OSGeo wiki, therefore,
I will share my wiky page as soon as possible.

Thanks for this great opportunity!

It is great to have you with us ! I’m looking forward to working
with you on this project.

First of all I want to thank you for being my mentor!

The first thing I would love to see is your existing python script
to get a better understanding of the exact approach you are planning
on implementing.

Depending on what tool you prefer, you can either set up a github
repository for the project, or you could also use the sandbox in the
GRASS svn [1]. You could then share your code there.

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.

Please also set up a wiki page about your project. See [0] for examples from last year.

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.

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.

Best wishes,
Moritz

Hi all!
I requested the right OSGeo user id and now I can log in and set up a wiki page for the project.

Regarding the development, I’ll use github for now but at the same time I can follow the procedure for access to the GRASS-Addons-SVN repository.

Thank you for your suggestions!

Thanks for this great opportunity!

It is great to have you with us ! I’m looking forward

First of all I want to thank you for being my mentor!

The first thing I would love to see is your existing
python script
to get a better understanding of the exact approach you
are planning
on implementing.

Depending on what tool you prefer, you can either set
up a github
repository for the project, or you could also use the
sandbox in the
GRASS svn [1]. You could then share your code there.

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.

Please also set up a wiki page about your project. See [0] for
examples from last year.

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

Hi all!
I requested the right OSGeo user id and now I can log in and set up a wiki page for the project.

Regarding the development, I’ll use github for now but at the same time I can follow the procedure for access to the GRASS-Addons-SVN repository.

Thank you for your suggestions!

Roberta

Your OSGeo_id is “Robifag”.

I give you write access to SVN add-ons GRASS repository, but I do not know how to give you access to trac system.

Please note that for access to the add-ons SVN, Roberta has to officially state in a mail to the PSC list that she has read and abides to RFC2 [1] (see [2] for more info).

I would suggest to develop in github for now and move to addons could then be done once the module is ripe. Or, as said earlier, to use the SVN sandbox for developing.

Hi Roberta,

Hi all!
I’m Roberta Fagandini, Ph.D. student at Politecnico
of Milano.
My proposal “GRASS GIS module for Sentinel-2 cloud
and shadow
detection” has been accepted therefore I’ve been
selected for
the GSoC 2018.
I’m glad to start contributing to OSGeo and
especially to GRASS
GIS with the help of my mentors Roberto Marzocchi
and Moritz
Lennert.

My project consists in the realization of a GRASS
GIS module for
the detection of clouds and their shadows in
Sentinel-2 images
without using time series.
Below you can find the link to my proposal:

https://docs.google.com/document/d/1mQyouqbHGHugn5DjEDZI3hc1eU_bT_b0qLJPPwkt_hk/edit?usp=sharing
<https://docs.google.com/document/d/1mQyouqbHGHugn5DjEDZI3hc1eU_bT_b0qLJPPwkt_hk/edit?usp=sharing>

<https://docs.google.com/document/d/1mQyouqbHGHugn5DjEDZI3hc1eU_bT_b0qLJPPwkt_hk/edit?usp=sharing>>

I would be grateful if you could have a look at the
proposal and
provide any suggestions.
Every feedback is welcome and it will be useful to
improve my
project.

I’m waiting for the writing access to the OSGeo
wiki, therefore,
I will share my wiky page as soon as possible.

Thanks for this great opportunity!

It is great to have you with us ! I’m looking forward
to working
with you on this project.

First of all I want to thank you for being my mentor!

The first thing I would love to see is your existing
python script
to get a better understanding of the exact approach you
are planning
on implementing.

Depending on what tool you prefer, you can either set
up a github
repository for the project, or you could also use the
sandbox in the
GRASS svn [1]. You could then share your code there.

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.

Please also set up a wiki page about your project. See [0] for
examples from last year.

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.

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.

Best wishes,
Moritz

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

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!

Moritz

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.
