pyguymer3.geo.extract_lines

pyguymer3.geo.extract_lines(shape, /, *, onlyValid=False)

Extract the LineStrings from the shape

This function accepts any Shapely geometry and returns a flat list of all of the LineStrings contained within.

Parameters:

• shape (list, shapely.geometry.point.Point, shapely.geometry.multipoint.MultiPoint, shapely.geometry.polygon.LinearRing, shapely.geometry.linestring.LineString, shapely.geometry.multilinestring.MultiLineString, shapely.geometry.polygon.Polygon, shapely.geometry.multipolygon.MultiPolygon, shapely.geometry.collection.GeometryCollection) – the Shapely geometry

• onlyValid (bool, optional) – only return valid LineStrings (checks for validity can take a while, if being called often)

Returns:

lines – a flat list of all of the LineStrings

Return type:

list of shapely.geometry.linestring.LineString

Notes

To pass GeoJSON objects you must first convert them to Shapely objects by doing something like shape = shapely.geometry.shape(shape).
