Description

The following exception is raised when adding a dataframe with a geometry column not named "geometry" to the map. If the geometry column is renamed to "geometry" before adding to the map, then everything goes well.

AttributeError: You are calling a geospatial method on the GeoDataFrame, but the active geometry column ('seg') is not present. 
There are columns with geometry data type (['geometry']), and you can either set one as the active geometry with df.set_geometry("name") or access the column as a GeoSeries (df["name"]) and call the method directly on it.

During handling of the above exception, another exception occurred:
