[GRASS-dev] GSoC Introduction: GRASS and Jupyter Notebooks

[Caitlin Haedrich]

Hello everyone,

My name is Caitlin Haedrich and I'm one of the OSgeo Google Summer of Code
participants. I'm a first year PhD student in Geospatial Analytics at North
Carolina State University in Raleigh, NC. You can read more about my
background and interests on my website [1].

This summer, I'll be working on improving the integration of GRASS GIS and
Jupyter Notebooks. I'm proposing a new python library, 'grass.jupyter',
that will contain functions for:
* initiating GRASS sessions in Jupyter
* displaying maps in a more intuitive way (wrapping 'd.erase' and other
required modules into one function)
* displaying interactive maps with folium

You can read more about the project in my proposal [2] and follow my
progress on the project wiki page [3].  I'd love to hear any ideas or
feedback you have for the project.

Lastly, I'd like to thank OSGeo and Google for giving me this opportunity.
I'm really looking forward to working with you all this summer and being
part of the OSGeo community.

Best,
Caitlin

Hi Stefan and Roberta,

We can probably help too -- I work on Antarctic datasets: relief,
clouds, and very cold, white surface!

Thank you so much!!
The cases you describe are "the best cases" for me, clouds and snow are
hard to distinguish and shadows are strongly dependent on land use/cover.
Now I'm working on the python script, as soon as it is ready I will share
it with the community and commit it to my GitHub repository [0]

Re: [GRASS-dev] GSoC introduction Roberta Fagandini

[Stefan Blumentrath]

Hi Roberta,

Here in Norway we can do some “worst case” testing for your algorithm. Plenty 
of snow and clouds in the mountains, and heavily rugged terrain, that 
presumably has quite some effect on cloud shadows…

Looking forward to following your project from the side!

Kind regards,
Stefan

Interesting to hear your results, Roberta -- the reason I brought this
up is that some of my colleagues (non-GRASS users :( ) tried it very
successfully.

Happy to follow up with them if need be,

Hi Pierre!
Thank you so much for your hints!
I have already tested Fmask with Sentinel 2 images but I didn't have great
results. However, it is worth investigating better!
Thanks for all the references!

Hi Roberta,

On top of the review linked by Vero, I thought I'd mention the Fmask
procedure -- it seems to give great results and there is a python
library on Github.

*Relevant GRASS GIS tickets*:

https://trac.osgeo.org/grass/ticket/3473
https://trac.osgeo.org/grass/ticket/3283

*Papers*:

https://www.researchgate.net/publication/324836341_Improvement_of_the_Fmask_algorithm_for_Sentinel-2_images_Separating_clouds_from_bright_surfaces_based_on_parallax_effects

*Software*:

Hopefully this is helpful,

 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!

Sorry, I misspelled the rule..the right meaning is (blue > 0.08 *

Thanks ! I think the most interesting part would actually be the
details of the two detection procedures, so it would be good to
detail them :-).


Yes, I will add all the rules from the procedure file. Then I'd like to 
send a new mail with all the links related to the project (wiki, github 
and schema) to the grass dev list asking for feedback, hints, etc. What

Good idea.

Yes, but it's only a test ;-) since I have to get familiar with the GRASS
Python scripting library, I tried to do something that could be useful
during the coding period.

You are right and I will investigate all these issues in the next days!
Today I want to update my wiki page with more details especially about the

I committed [1] the first results of the procedure. In this case, I used

For GSoC, don't forget that you are in bonding period right now, so IMHO 
the most important is to get the schema out and discuss it with the 
community and to familiarize yourself with GRASS programming. Now that 
you have managed to program a Python script, you should look into how to 
make this into a module, i.e. how to use the parser instructions, how to 
create a Makefile and things like that.


The actual coding and testing of results can come during coding period 
starting next week.


Best wishes,
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.

Yes, I started working with GRASS Python scripting library. I'm

existing GRASS scripts [1,2] and moreover, Roberto gave me one
of his scripts as an example. I have just committed the first

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

using several images sensed in different seasons, latitude, etc.

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!

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.


Best wishes,
Moritz

I fully agree, I think small patches (for example a patch for each

yes, to start you can just launch GRASS and from the command line in
GRASS launch a Python3 console, it work.

Please use standard North Carolina dataset [0], the tests actually use
the "basic" version of the dataset

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!

 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

 Thanks for this great opportunity!


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

 The first thing I would love to see is your existing python script

 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

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.

welcome! For start, please create a wiki page on trac wiki (you should
already have access there), look at the examples from the past years,
and follow similar structure:
https://trac.osgeo.org/grass/wiki/GSoC

We will need to decide how to manage your contributions, since you
won't have access rights to the svn repository. We might need to do it
similarly as we did with one student 2 years ago, he tracked the
applied changesets in his github repository, which could be then
submitted to Google in the end of the program. You could post your
changes in tickets (created specifically for this GSoC) and they will
be applied by me, Luca or other developers. I understand this is not
ideal workflow, so if anybody has better idea, let me know.

For the community bonding period there are couple things I suggest.
* make sure you have all the development environment ready (you
probably have that already)
* have good idea about the code structure
* make yourself familiar with the testing framework, I would like you
to use it to update current tests of the libraries, adjust them to
work with Python3 and write new tests:
  https://grass.osgeo.org/grass74/manuals/libpython/gunittest_testing.html
  http://fatra.cnr.ncsu.edu/grassgistests/summary_report/
* specifically start looking at Python scripting library, it would be
great if you could start working on it during the bonding period,
specific challenges you may encounter there may help us get the
discussion going.

I will let you know if I think of more things. Please send your
questions/concerns either directly to me and Luca, or copy also the
grass-dev mailing list, so that we can keep other developers in the
loop.

Thank you and looking forward to working with you,

Anna

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.

My project consists in the realization of a GRASS GIS module for the

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.

[GRASS-dev] GSoC Introduction

[Sanjeet]

Hi everyone,

My name is Sanjeet Bhatti and I have got selected for GSOC 2018 in
GRASS GIS. My project is "Full support of Python 3 in GRASS GIS" with
Anna Petrášová and Luca Delucchi as my mentors.

Here is my project proposal and everyone is welcome to give
suggestions and feedback:
https://docs.google.com/document/d/18kD6I7adTKmtXpGOKr4A8hf1pBcf0LNU7jiiRoi9wJ8

This will certainly help me in understanding the requirements and
flesh out the ideas that I would be implementing in the coding period.

I will soon share my wiki page where I'll be reporting my progress
throughout the GSoC period, once I receive the writing access to the
OSGeo wiki.

Thank you so much for giving me this opportunity. I am excited to be
part of OSGeo and GRASS GIS community.

Thanks

 Hello,

 I would like to introduce my topic for  GSoC.

 My proposal for GSoC is porting of module i.ortho.photo into GRASS 7. The
 module is  based on x monitors, which support was removed  from
 GRASS 7, so
 it  is needed to integrate the ortorectification into wxGUI. The
 x-monitor
 support is related to these imaginary functions:
     photo.2image
     photo.2target

 That would be core of my work in GSoC.

 Waiting for your feedback! Do you consider this topic to be suitable for
 GSoC?

Definitively! I have converted X-terminal based i.points to the wxGUI
and worked on the i.ortho.photo suite, so please do not hesitate to
ask me if you have any questions! You should be able to recycle quite
a bit of the wxGUI georectifier for a new wxGUI orthorectifier, in
particular for i.photo.2target.

 I already have some experience
 in developing in GRASS. This semester I have
 been working on my bachelors thesis, which is focused on implementation on
 WMS support into GRASS GIS and SAGA GIS. So far I have rewritten module
 r.in.wms. This or next week the module should be accessible for testing on
 GRASS
 Addons SVN with name r.in.wms2.

 Thanks,

 Stepan

Maybe, the GUI for i.ortho.photo could be the same of i.points?
The user could choose between georectifier and orthorectifier
Maybe this proposal could integrate also something else?

Ahoj Stepane,

I was working with my collegue Vaclav on wxIClass which was based on
old i.class module (available only for X monitor) [1][2]. So don't
hesitate to ask us in case of some problems with wxGUI. Good luck with
your GSoC application.
