#TodayILearned that if you do a .dissolve() on a #geopandas #GeoDataFrame "by" a certain column, it becomes "an index" thus, kind of hidden. You can regain access to it with .reset_index()

Also, when merging two gdfs it can be useful to first select just the relevant columns from one of them, in order to preserve the geometry column of the other...

...at least this is how it looks like how it worked for me...

while exploring @geopandas docs I learned it has a "explore()" function that creates an interactive #leafletjs map of the #geodataframe #pandas #gis #geodata #gischat #geopandas

@natera cheers Luis...

I've learned to get things just inside a bounding box...https://github.com/villares/sketch-a-day/blob/main/2023/sketch_2023_08_25/sketch_2023_08_25.py but I'm struggling with the documentation :(
I don't have a very definite goal but I'm exploring some ideas. I'd like to highlight a a chosen street and calculate it's length in meters.

I can convert a #osmnx graph to a #GeoDataFrame, just edges, and select named edges. But then I can't convert them back to a network (because I don't have nodes? Because I'm using the wrong methods?)
Can I plot the gdf together with the graph? Maybe I should learn to extract the nodes?

I can see some shapely geometry inside the dataframes, I wish I could convert/project it's coordinates to meters and then to some "screen coordinates" so I can draw them myself with #py5 instead of matplotlib (I never use matplotlib so I'm perpetually confused by it).

And don't worry if you can't help me much with this...

Update: I learned how to get the gdf (edged, nodes) tuple and I can highlight the selected street :)

I ran into issues with @geopandas explore today when the #geodataframe included datetime columns. Still have to check if this is a known issue and then create a reproducible example
