Polyline

A polyline contains an array of paths or curvePaths and a spatialReference. For polylines with curvePaths, see the sections on JSON curve object and Polyline with curve. Each path is represented as an array of points, and each point in the path is represented as an array of numbers. A polyline can also have valued hasM and hasZ as boolean fields.

See the description of multipoints for details on how the point arrays are interpreted.

An empty polyline is represented with an empty array for the paths field. Nulls and/or NaNs embedded in an otherwise defined coordinate stream for polylines/polygons is a syntax error.

Polygon

A polygon contains an array of rings or curveRings and a spatialReference. For polygons with curveRings, see the sections on JSON curve object and Polygon with curve. Each ring is represented as an array of points. The first point of each ring is always the same as the last point. Each point in the ring is represented as an array of numbers. A polygon can also have Boolean-valued hasM and hasZ fields.

See the description of multipoints for details on how the point arrays are interpreted.

An empty polygon is represented with an empty array for the rings field. Nulls and/or NaNs embedded in an otherwise defined coordinate stream for polylines/polygons is a syntax error.

Polygons should be topologically simple. Exterior rings are oriented clockwise, while holes are oriented counter-clockwise. Rings can touch at a vertex or self-touch at a vertex, but there should be no other intersections. Polygons returned by services are topologically simple.

When drawing a polygon, use the even-odd fill rule. The even-odd fill rule will guarantee that the polygon will draw correctly even if the ring orientation is not as described above.

When adding elements to a GeometryBag, keep in mind that the elements acquire the spatial reference of the bag. If the spatial reference of the bag is null, for example, and the element references a well-defined spatial reference, then the element will lose that reference when it is added to the bag.

Property	Type	Description
hasM	boolean	Indicates whether the geometry contains M coordinate values.
hasZ	boolean	Indicates whether the geometry contains Z coordinate values.
points	[Geometry]	Array of Geometry
spatialReference	SpatialReference	The spatial reference can be defined using a well-known ID (WKID) or well-known text (WKT).

Curves

A curve object is a segment in a polyline or polygon. It cannot be used as a stand-alone object.

A curve object is given in a compact "curve to" manner with the first element representing the "to" point or end point. The "from" point is derived from the previous segment or curve object.

The supported curve objects are as follows:

• Circular Arc
• Elliptic Arc
• Bézier Curve

CircularArc

A Circular Arc is an object that describes any portion of a circle. A CircularArc differs from an EllipticArc in that every point along the CircularArc must be a fixed distance (the Radius) from the center.

Circular Arc is defined by an end point and an interior point. It is identified by the member "c" and can be represented in JSON as {"c": [[x, y, <z>, <m>],[interior_x, interior_y]]}

Property	Type	Description
c	[Point]	In the array, first element represents end point and the second element represents interior point

Alternatively, a Circular Arc may be defined as a special case of the Elliptic Arc notation without rotation, axis, or ratio specified: {"a": [[x, y, <z>, <m>],[center_x, center_y],minor, clockwise]}

EllipticArc

An Elliptic Arc is an object that describes any portion of an ellipse.

Elliptic Arc is defined by end point, center point, axis, arc orientation, angle from major axis in radians, length of semi major axis and ratio of the minor axis to the major axis and can be represented in JSON as follows: {"a": [[x, y, <z>, <m>],[center_x, center_y], minor, clockwise, rotation, axis, ratio]}

Property	Type	Description
a	[Point (end point), Point (center point), number(minor), number(clockwise), number(rotation), number(axis), number(ratio)]	Array elements should be in the following order : End point Center Point minor (0: arc is major, 1: arc is minor - less than 180 degrees) clockwise(0: counter clockwise, 1: clockwise) rotation: angle of rotation of major axis in radians with a positive value being counterclockwise axis: length of the semi-major axis ratio: ratio of the minor axis to major axis

If rotation, axis, and ratio are not specified with the Elliptic Arc, the object is a special case of Elliptic Arc that is a Circular Arc.

BézierCurve

A cubic Bézier Curve is a non-linear Segment defined by four control points. The Bézier curve starts at control point 0 and ends at control point 3. Control points 0 and 1 define the tangent at the from point and control points 2 and 3 define the tangent at the to point. The length of these tangent lines and position of the control points determines the shape of the created bézier curve.

Property	Type	Description
