Shapely: Polygon from String?

Valeria picture Valeria · Aug 15, 2018 · Viewed 18.8k times · Source

I have saved string representations of some Shapely Polygons:

'POLYGON ((51.0 3.0, 51.3 3.61, 51.3 3.0, 51.0 3.0))'

Is there some fast way of directly converting it back to the Polygon type? Or do I need to manually parse the strings to create Polygon objects?

Shapely can directly parse this:

import shapely.wkt

P = shapely.wkt.loads('POLYGON ((51.0 3.0, 51.3 3.61, 51.3 3.0, 51.0 3.0))')
print(P)
