Inspector tool with folium?

[albertlarson]

I am using colab for a workshop with some students. I am replicating a tutorial from the vanilla GEE website about Global Water Occurrence. When I add the map layer, I am finding that inspector only shows lat/long. Is it possible to include the variable as well? Code is below. Thanks. -Albert

f = folium.Figure(width=600,height=300)
Map = geemap.Map(zoom=2).add_to(f)

gsw = ee.Image('JRC/GSW1_0/GlobalSurfaceWater')
occurrence = gsw.select('occurrence')
Map.addLayer(occurrence,{},'Water Occurrence')
Map

Unfortunately, the answer is no. Unlike ipyleaflet, folium is a one-way street from Python to Javascript (see python-visualization/folium#1402 and python-visualization/folium#1388). Once the map is created and displayed, there is not much interactivity except zooming in/out and toggling layers on/off. You cannot even get the clicked coordinates programmatically, not to mention querying GEE data, adding/removing layers, etc. If it were possible, I would have implemented this basic inspector feature.

If your students can't set up jupyter on their computer, here are two potential workarounds:

• Use HydroShare, which has geemap integrated into their JupyterLab env. See this tutorial.
• Use Voila, which can be hosted on your local computer and accessed by students. See this tutorial and demo (https://app.geemap.org)

Too bad about folium. I suppose in the long run we can patiently wait for the implementation in ipyleaflet.

HydroShare seems pretty neat, if not for this project than maybe for another. Thanks for getting back to me.
