Kristin Cowalcijk created SEDONA-456:
----------------------------------------
Summary: SedonaKepler cannot work with geopandas >= 0.13.0
correctly
Key: SEDONA-456
URL: https://issues.apache.org/jira/browse/SEDONA-456
Project: Apache Sedona
Issue Type: Bug
Affects Versions: 1.5.0
Reporter: Kristin Cowalcijk
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.
{code}

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.
