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. >>> 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|tkr|S|jstd|j}n5t |dr+t |}t|t j r:t |jt jr:nddt fdd|D}t |jt jsVtdt|d kratdSt|}t|tsotd |S) NzLINEARRING EMPTYz"An input LineString must be valid. __array__cSs"t|tr |jdSdd|DS)NrcSg|]}t|qSr)float.0crrr [z7LinearRing.__new__.._coords..) isinstancercoords)orrr_coordsWs  z#LinearRing.__new__.._coordscsg|]}|qSrr)rr#r$rrr]r z&LinearRing.__new__..z&Inconsistent coordinate dimensionalityrz/Invalid values passed to LinearRing constructor)r from_wktr!rtyper is_validrr"hasattrnpasarrayndarray issubdtypedtypenumberarray ValueErrorlenr)self coordinatesgeomrr%r__new__>s0         zLinearRing.__new__cCsdt|jdS)Nr r'r4)tupler"r3rrr__geo_interface__mszLinearRing.__geo_interface__cCsttj|ddffS)zWKB doesn't differentiate between LineString and LinearRing so we need to move the coordinate sequence into the correct geometry typeT) include_srid)rr to_wkbr9rrr __reduce__qszLinearRing.__reduce__cCstt|S)z/True is the ring is oriented counter clock-wise)boolrr9rrris_ccwvszLinearRing.is_ccwcCstt|S)zsTrue if the geometry is simple, meaning that any self-intersections are only at boundary points, else False)r>r is_simpler9rrrr@{szLinearRing.is_simpler ) __name__ __module__ __qualname____doc__ __slots__r6propertyr:r=r?r@rrrrr s" /  r c@sLeZdZdZdZdZdZddZddZddZ d d Z d d Z d dZ dS)InteriorRingSequenceNrcCs||_|j|_dSr )_parent_ndim)r3parentrrr__init__s zInteriorRingSequence.__init__cCsd|_||_|S)Nr)_index__len___lengthr9rrr__iter__s zInteriorRingSequence.__iter__cCs.|j|jkr||j}|jd7_|St)N)rMrO _get_ring StopIteration)r3ringrrr__next__s  zInteriorRingSequence.__next__cCs t|jSr )r get_num_interior_ringsrIr9rrrrNs zInteriorRingSequence.__len__cCs|}t|tr'||dks||krtd|dkr ||}n|}||St|trIg}||\}}}t|||D] }|||q<|St d)Nrzindex out of rangezkey must be an index or slice) rNr!int IndexErrorrRsliceindicesrangeappend TypeError)r3keymiresstartstopstriderrr __getitem__s    z InteriorRingSequence.__getitem__cCst|j|Sr )r get_interior_ringrI)r3r`rrrrRszInteriorRingSequence._get_ring) rArBrCrIrJrMrOrLrPrUrNrerRrrrrrHs rHcs|eZdZdZgZdddZeddZeddZed d Z d d Z fd dZ eddZ dddZ eddZZS)r aE A geometry type representing an area that is enclosed by a linear ring. 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 >>> 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)Nz POLYGON EMPTYrcSrr)r )rrTrrrrr z#Polygon.__new__..)holesz,Invalid values passed to Polygon constructor)r r&r!r r r2polygonsr1)r3shellrgr5rrrr6s    zPolygon.__new__cCs t|Sr )r get_exterior_ringr9rrrexteriors zPolygon.exteriorcCs|jrgSt|Sr )is_emptyrHr9rrr interiorsszPolygon.interiorscCstd)NzCComponent rings have coordinate sequences, but the polygon does not)NotImplementedErrorr9rrrr"szPolygon.coordscCst|tstSt|tsdS|j|jf}t|rdSt|r dS|jjgdd|j D}|jjgdd|j D}t |t |ksDdSt ddt ||DS)NFTcSg|]}|jqSrr"rinteriorrrrrz"Polygon.__eq__..cSrorrprqrrrrrscSsg|] \}}t||qSr)r* array_equal)rleftrightrrrrs ) r!rNotImplementedr rlallanyrkr"rmr2r*zip)r3other check_empty my_coords other_coordsrrr__eq__s,   zPolygon.__eq__cs tSr )super__hash__r9 __class__rrrs zPolygon.__hash__cCsJ|jtkr g}nt|jjg}|jD] }|t|jqdt|dS)Nr r7)rkr r8r"rmr\)r3r"holerrrr:!s  zPolygon.__geo_interface__?cCs||jrdS|dur|jrdnd}|durd}dd|jjDg}dd|jD}d d d||D}d d ||||S) aReturns SVG path element for the Polygon geometry.
