Buffering Geometries in GeoDataFrame

This function takes a GeoDataFrame and a buffer distance as input, applies a buffer operation to each geometry in the GeoDataFrame, and returns a new GeoDataFrame containing the buffered geometries.

Technology Stack : GeoPandas, Shapely

Code Type : Geographic data processing

Code Difficulty : Intermediate
