GeoSeries

GeoSeries is a data structure in GeoPandas for storing an ordered collection of geometric objects, such as points, lines, and polygons. It extends the capabilities of a pandas Series with geospatial information and carries an associated coordinate reference system (CRS). GeoSeries serves as the geometry container that integrates with common geospatial workflows in Python.

Each element in a GeoSeries is a geometry object, typically provided by the Shapely library. A GeoSeries can be used on its own or as the geometry column of a GeoDataFrame. It exposes properties and methods related to geometry type and supports spatial predicates and operations through its GeoPandas integration. The CRS attached to a GeoSeries ensures that coordinates are interpreted consistently when combining datasets or performing transformations.

Common usage involves constructing a GeoSeries from a list of geometries and optionally specifying a CRS; the series can then be embedded as the geometry column in a GeoDataFrame or used to store geometric data independently. Reprojection and other spatial transformations can be applied to the series through its data frame context. While GeoSeries focuses on geometry data, more complex analyses typically rely on a GeoDataFrame, which pairs geometry with non-geometric attributes and provides additional spatial operations.

In summary, GeoSeries provides a lightweight, geometry-centric container for geospatial data, enabling straightforward storage, access, and interaction of geometric objects within the GeoPandas ecosystem.
