Respected Professor and all,

Namaskar!

I fully agree with the proposed timeline for the January 2026 release and would be very happy to contribute new features and notebook examples to PyGILE. I look forward to hearing about Job-san's modifications to the STAC-related RS notebooks and the numpy version issue resolution. I am currently preparing for the ATC exam, which is scheduled to conclude by the first week of December. I will begin working on PyGILE once my exam period is completed.

Thank you!

Hi All, Thank you, Venka-Sensei, for adding me to this list. I'm happy to be here and I appreciate the invitation and look forward to contributing. And Yes, Venka-Sensei, I'll update the modifications that I made on STAC related notebooks and also about the NumPy version issue.

Hi All,

I have added Job-san to this list.

Job-san, you can report the modification you made to get the STAC related RS notebooks [1] working and also about numpy version issue.

Bhuwan, with the experience gained over the last 6 months, we can plan a new release of PyGILE plus, including updates and more notebook examples. Maybe we could release the new version sometimes in Jan. 2026.

Let me know your thoughts

Best,

Venka

Hi All,

I just had a Zoom meeting with Bhuvan updating about recent examples of using STAC and GRASS in PyGILE-Plus.

Also, we had a talk on possibility of Bhuvan joining us in Mumbai.

Job-san, Lam-san, please discuss about your schedule for India trip with Bhuvan and also share with him details about any issue you face in deploying STAC and GRASS based jupyter notebooks.

Best,

Venka

P.S. I heard that Bhuvan and Lam had scheduled a meeting for today. Job-san, you can join this meeting too, if you are free.

Respected Professor and All,

I have developed a series of notebooks for PyGILE-Plus, organized into seven modules: Introduction to PyGILE-Plus, Configuration, SAGA Tutorial, GRASS Tutorial, OTB Tutorial, Whitebox Tutorial, Python Ecosystem, and Watershed Delineation. The accompanying markdown files outline the overall objectives for each section.

I believe these materials could be integrated into the upcoming PyGILE-Plus upgrade. I have attached the notebooks here for your reference. While the conceptual framework and workflow design are my own, I used AI tools to assist with portions of the code implementation.

Hi Bhuvan,

Thanks for preparing the updated notebooks.

My comments regarding the flow is as below

a) "06_Python_Geospatial_Ecosystem.ipynb" can be the second notebook b) Perhaps we can show Watershed Delineation (07_Watershed_Delineation.ipynb) in the third step and show all SAGA, GRASS, OTB and Whitebox examples only within the delineated watershed.

some other thoughts about visualization

a) Can we show 3D model of DEM using pythreejs and pyvista. I think they are is already available in PyGILE-Plus. ----Code---

# (Requires 'pip install pyvista')import pyvista as pvfrom pyvista.jupyter import set_jupyter_backend # Use the pythreejs backend set_jupyter_backend('pythreejs') # Load or create your DEM data (e.g., from a GeoTIFF file)# mesh = pv.read('your_dem_file.tif') # Example with sample data:dem_data = np.random.rand(100, 100)mesh = pv.from_array(dem_data) # Plotting in the Jupyter notebook with interactive controls mesh.plot(jupyter_backend='pythreejs')

---

b) can we show example of using OSM in the background and overlaying the computed results over the osm. Maybe we can use leafmap or ipyleaflet (example links below).
