| Method | Defined By | ||
|---|---|---|---|
geodesicAreas(polygons:Array, areaUnit:String):Array [static]
Gets the area array of the input polygon array with the specified area unit. | GeometryUtil | ||
[static]
Returns a densified polyline or a polygon (depending on the input geometry). | GeometryUtil | ||
geodesicLengths(polylines:Array, lengthUnit:String):Array [static]
Gets the length array of the input polyline array with the specified length unit. | GeometryUtil | ||
normalizeCentralMeridian(geometries:Array, geometryService:GeometryService, responder:IResponder):void [static]
Normalizes geometries that intersect the central meridian or fall outside the valid world extent so they stay within the current coordinate system. | GeometryUtil | ||
polygonSelfIntersecting(polygon:Polygon):Boolean [static]
Returns true when the ring of the polygon intersect itself. | GeometryUtil | ||
| geodesicAreas | () | method |
public static function geodesicAreas(polygons:Array, areaUnit:String):ArrayGets the area array of the input polygon array with the specified area unit. The input polygon must be in a geographic coordinate system. The area will be calculated using a custom cylindrical equal-area projection. Note that the polygons cannot be self-intersecting. The method polygonSelfIntersecting is provided to check the self-intersecting. If the polygons are self-intersecting, use the geometry service to simplify the polygon before calculating the area.
Parameters
polygons:Array — The input polygons whose areas are to be calculated.
| |
areaUnit:String — The area unit for the returned areas.
|
Array — Array of areas corresponding to input Array.

| geodesicDensify | () | method |
public static function geodesicDensify(geometry:Geometry, maxSegmentLength:Number = 10000):GeometryReturns a densified polyline or a polygon (depending on the input geometry). The input polyline or polygon must be in a geographic coordinate system.
Parameters
geometry:Geometry — The polyline or polygon to densify.
| |
maxSegmentLength:Number (default = 10000) |
Geometry — A geodesic densified polyline or polygon.

| geodesicLengths | () | method |
public static function geodesicLengths(polylines:Array, lengthUnit:String):ArrayGets the length array of the input polyline array with the specified length unit. The input polyline must be in a geographic coordinate system. The length will be calculated using a custom cylindrical equal-area projection.
Parameters
polylines:Array — The input polylines whose lengths are to be calculated.
| |
lengthUnit:String — The length unit for the returned lengths.
|
Array — Array of lengths corresponding to input Array.

| normalizeCentralMeridian | () | method |
public static function normalizeCentralMeridian(geometries:Array, geometryService:GeometryService, responder:IResponder):voidNormalizes geometries that intersect the central meridian or fall outside the valid world extent so they stay within the current coordinate system. Only supported for Web Mercator and geographic coordinates.
Parameters
geometries:Array — The input geometries to be normalized.
| |
geometryService:GeometryService — The geometry service instance to use.
| |
responder:IResponder — The responder to call on result or fault.
|
| polygonSelfIntersecting | () | method |
public static function polygonSelfIntersecting(polygon:Polygon):BooleanReturns true when the ring of the polygon intersect itself. When true, consider simplifying the polygon to make sure it becomes topologically consistent. This can be done using the simplify method of the GeometryService.
Parameters
polygon:Polygon — The polygon to be tested for self-intersection.
|
Boolean — Returns true if the ring of the polygon intersects itself; false otherwise.
