YES, I STARTUP - Crea la Tua Startup in 100 giorni LinkCode for converting Multi to Single Polygon. def convert_to_multipolygon(geoms): from shapely.geometry import MultiPolygon rings = [] for geom in geoms: if isinstance(geom, MultiPolygon): rings = rings + [geom for geom in geom.geoms] else: rings = rings + [geom] geometry = MultiPolygon(rings) # Downsample 3D -> 2D wkt2d = geometry.to_wkt() geom2d = shapely.wkt.loads(wkt2d) return geom2d Vous pouvez utiliser la fonction de forme de Shapely: from shapely.geometry import shape c = fiona.open('data/boroughs/boroughs_n.shp') pol = c.next() geom = shape(pol['geometry']) et un MultiPolygon est une liste de polygones, donc Multi = MultiPolygon( [shape(pol['geometry']) for pol in fiona.open('data/boroughs/boroughs_n.shp')]) Shapely and geometric objects - Read the Docs individual polygons with. In the example above, you dissolved the state level polygons to a region level. union seems to produce a polygon if the 2 objects intersect and a multipolygon if not. Useful attributes and methods in Shapely include: Creating lines and polygons based on a collection of point objects. geometry. Creating and editing multipart polygons—Help | ArcGIS for Desktop coords = [(24.950899, 60.169158), (24.953492, 60.169158), (24.953510, 60.170104), (24.950958, 60.169990)] poly = Polygon(coords) hospitals = ox.pois.osm_poi_download(polygon=poly, amenities=['hospital']) How many hospitals do we have in this district? polygon import Polygon: from shapely. Thanks Converting Shapely MultiPolygon to Polygon: Technique … In my previous two posts, I showed how to (1) read and plot shapefile geometries using the pyshp library an The signed area of the result will have the given sign. MultiPolygon-object represents a collection of polygons that consists of a list of polygon-like sequences that construct from exterior ring and (possible) hole list tuples. 1.2.14 (2012-01-23) A geometry’s coords property is now sliceable, yielding a list of coordinate values. This is the first appearance of an explicit polygon handedness in Shapely. This is the first appearance of an explicit polygon handedness in Shapely. To obtain a polygon with a known orientation, use shapely.geometry.polygon.orient(): shapely.geometry.polygon.orient(polygon, sign=1.0)¶ Returns a properly oriented copy of the given polygon.
