grass.jupyter: Allow users to draw simple geometries and save it as vector

[29riyasaxena]

Hi Everyone,

This pull request adds a new feature to grass.jupyter.interactivemap.py: a "Draw Geometries" button that lets users create and add geometries to the map as a GRASS native vector map.

Here’s how it works:

1. Click the Pencil button to activate the drawing tool.
2. You can then draw a polyline, polygon, or circle marker on the map.
3. Enter a name for the new vector map in the "New vector map name" text box.
4. Click the Save button to finalize and add the geometry.
5. The new layer will be added to the map, and the drawing interface will automatically close.

For a visual guide, please check out the following recording:

Right now it's not creating a GRASS vector, it's just adding geojson layer to the map. The vector needs to be imported, I think v.import should do that as we discussed before.

should do

Hi Anna,
Yes, I remember. I hadn't thought of saving them as vectors. Sorry about that. I've pushed the changes now.

This is not working, in the jupyterlab log I get:

Failed to import geometries into GRASS GIS: a bytes-like object is required, not 'str'

Please test more. Run it in the notebook and check the output is correctly written as a vector map.

Hi Anna, I can successfully add vectors and save them, but I am stuck on the part when deleting them. I tried clearing all the geometries and removing layers when clicking the delete button, but things aren't working. Could you please share your opinions on this?
