Supports WKT for POINT, MULTIPOINT, LINESTRING, MULTILINESTRING, POLYGON, MULTIPOLYGON, and GEOMETRYCOLLECTION. *Parameters* ``wkt {String}`` A WKT string *Returns* {|Array} A feature or array of features for GEOMETRYCOLLECTION WKT. .. _write: write :: write: function(features) Serialize a feature or array of features into a WKT string. *Parameters* ``features {|Array}`` A feature or array of features *Returns* ``{String}`` The WKT string representation of the input geometries .. _extract: extract Object with properties corresponding to the geometry types. Property values are functions that do the actual data extraction. .. _parse: parse Object with properties corresponding to the geometry types. Property values are functions that do the actual parsing. .. _parse.point: parse.point Return point feature given a point WKT fragment. *Parameters* ``str {String}`` A WKT fragment representing the point *Returns* :ref:`{ZOO.Feature} ` A point feature .. _parse.multipoint: parse.multipoint Return a multipoint feature given a multipoint WKT fragment. *Parameters* ``str {String}`` A WKT fragment representing the multipoint *Returns* :ref:`{ZOO.Feature} ` A multipoint feature .. _parse.linestring: parse.linestring Return a linestring feature given a linestring WKT fragment. *Parameters* ``str {String}`` A WKT fragment representing the linestring *Returns* :ref:`{ZOO.Feature} ` A linestring feature .. _parse.multilinestring: parse.multilinestring Return a multilinestring feature given a multilinestring WKT fragment. *Parameters* ``str {String}`` A WKT fragment representing the multilinestring *Returns* :ref:`{ZOO.Feature} ` A multilinestring feature .. _parse.polygon: parse.polygon Return a polygon feature given a polygon WKT fragment. *Parameters* ``str {String}`` A WKT fragment representing the polygon *Returns* :ref:`{ZOO.Feature} ` A polygon feature .. _parse.multipolygon: parse.multipolygon Return a multipolygon feature given a multipolygon WKT fragment. *Parameters* ``str {String}`` A WKT fragment representing the multipolygon *Returns* :ref:`{ZOO.Feature} ` A multipolygon feature .. _parse.geometrycollection: parse.geometrycollection Return an array of features given a geometrycollection WKT fragment. *Parameters* ``str {String}`` A WKT fragment representing the geometrycollection *Returns* ``{Array}`` An array of ZOO.Feature
