A LinearRing is a closed, one-dimensional feature. A LinearRing that crosses itself or touches itself at a single point is invalid and operations on it may fail. Parameters ---------- coordinates : sequence A sequence of (x, y [,z]) numeric coordinate pairs or triples, or an array-like with shape (N, 2) or (N, 3). Also can be a sequence of Point objects. Notes ----- Rings are automatically closed. There is no need to specify a final coordinate pair identical to the first. Examples -------- Construct a square ring. >>> from shapely import LinearRing >>> ring = LinearRing( ((0, 0), (0, 1), (1 ,1 ), (1 , 0)) ) >>> ring.is_closed True >>> list(ring.coords) [(0.0, 0.0), (0.0, 1.0), (1.0, 1.0), (1.0, 0.0), (0.0, 0.0)] >>> ring.length 4.0 Ncs|dur tdSt|tr!t|tur|S|jstd|j}n5t |dr+t |}t|t j r:t |jt jr:nddt fdd|D}t |jt jsVtd t|d kratdSt|}t|tsotd |S) z!Create a new LinearRing geometry.NzLINEARRING EMPTYz"An input LineString must be valid.Z __array__cSs"t|tr |jdSdd|DS)NrcSg|]}t|qSr )float.0cr r r [z7LinearRing.__new__.._coords..) isinstancercoords)or r r_coordsWs  z#LinearRing.__new__.._coordscsg|]}|qSr r )rrrr rr]rz&LinearRing.__new__..z&Inconsistent coordinate dimensionalityrz/Invalid values passed to LinearRing constructor)r from_wktrrtyperis_validrrhasattrnpZasarrayZndarrayZ issubdtypeZdtypenumberarray ValueErrorlenZ linearrings)self coordinatesgeomr rr__new__=s0         zLinearRing.__new__cCsdt|jdS)z9Return a GeoJSON-like mapping of the LinearRing geometry.rrr&)tuplerr%r r r__geo_interface__mszLinearRing.__geo_interface__cCsttj|ddffS)zPickle support.

A polygon is a two-dimensional feature and has a non-zero area. It may have one or more negative-space "holes" which are also bounded by linear rings. If any rings cross each other, the feature is invalid and operations on it may fail. Parameters ---------- shell : sequence A sequence of (x, y [,z]) numeric coordinate pairs or triples, or an array-like with shape (N, 2) or (N, 3). Also can be a sequence of Point objects. holes : sequence A sequence of objects which satisfy the same requirements as the shell parameters above Attributes ---------- exterior : LinearRing The ring which bounds the positive space of the polygon. interiors : sequence A sequence of rings which bound all existing holes. Examples -------- Create a square polygon with no holes >>> from shapely import Polygon >>> coords = ((0., 0.), (0., 1.), (1., 1.), (1., 0.), (0., 0.)) >>> polygon = Polygon(coords) >>> polygon.area 1.0 NcCst|dur tdSt|tr|St|}|dur(t|dkr!d}ndd|D}tj||d}t|ts8td|S)zCreate a new Polygon geometry.Nz POLYGON EMPTYrcSrr )r)rrEr r rrrz#Polygon.__new__..)holesz,Invalid values passed to Polygon constructor)r rrr rr$Zpolygonsr#)r%shellrUr'r r rr(s    zPolygon.__new__cCs t|S)z(Return the exterior ring of the polygon.)r Zget_exterior_ringr+r r rexteriors zPolygon.exteriorcCs|jrgSt|S)z5Return the sequence of interior rings of the polygon.)is_emptyr9r+r r r interiorsszPolygon.interiorscCstd)zNot implemented for polygons.zCComponent rings have coordinate sequences, but the polygon does not)NotImplementedErrorr+r r rrszPolygon.coordscCsJ|jtkr g}nt|jjg}|jD] }|t|jqdt|dS)z6Return a GeoJSON-like mapping of the Polygon geometry.r r))rWrr*rrYrL)r%rholer r rr,s  zPolygon.__geo_interface__?c Cs|jrdS|dur|jrdnd}|durd}dd|jjDg}dd|jD}d d d||D}d |d d |d|d|d S)aReturn SVG path element for the Polygon geometry.
