fill_polygon_holes#

fill_polygon_holes(gpd_results: GeoDataFrame, threshold: float | None = None) → GeoDataFrame[source]#

Fill holes over a given threshold on the hole area (in meters) for all polygons of a GeoDataFrame. If the threshold is set to None, every hole is filled.

Parameters:

  • gpd_results (gpd.GeoDataFrame) – Geodataframe filled whith drilled polygons

  • threshold (float) – Holes area threshold, in meters. If set to None, every hole is filled.

Returns:

GeoDataFrame with filled holes

Return type:

gpd.GeoDataFrame

Example

>>> # Open a polygon with holes
>>> holes = vectors.read("holes.geojson")
>>> # This polygons has interiors features, it has holes
>>> holes.interiors
