dtoolkit.geoaccessor.geoseries.select_geom_type(s: gpd.GeoSeries, geom_type: GEOM_TYPE, /, complement: bool = False) → gpd.GeoSeires[source]#

Select geometries by geometry type.

Parameters

geom_type{“Point”, “MultiPoint”, “LineString”, “LinearRing”, “MultiLineString”, “Polygon”, “MultiPolygon”, “GeometryCollection”}: Geometry type.
complementbool, default False: If True, do operation reversely.

Returns

GeoSeries: GeoSeries with selected geometries.
