List layers available in a file.

Provides an overview of layers available in a file or URL together with their geometry types. When supported by the data source, this includes both spatial and non-spatial layers. Non-spatial layers are indicated by the "geometry_type" column being None. GeoPandas will not read such layers but they can be read into a pd.DataFrame using pyogrio.read_dataframe().

Either the absolute or relative path to the file or URL to be opened, or any object with a read() method (such as an open file or StringIO)


A DataFrame with columns “name” and “geometry_type” and one row per layer.
