Object: esri/geometry/geodesicUtils
[ AMD Module Require | Legacy Module Require ]
require(["esri/geometry/geodesicUtils"], function(geodesicUtils) { /* code goes here */ });
Description
(Added at v3.8)
Utility methods for various geodesic calculations. When coding legacy (non-AMD) style, there is no need to require the module. All methods and properties are available in the namespace. For example,
esri.geometry.geodesicAreas().Samples

| Name | Return type | Summary |
|---|---|---|
| geodesicAreas(polygons, areaUnit) | Number[] | Determine the area for the input polygons. |
| geodesicDensify(geometry, maxSegmentLength) | Geometry | Returns a densified geometry. |
| geodesicLengths(polylines, lengthUnit) | Number[] | Determine the length for the input polylines using the specified length unit. |
Method Details
Determine the area for the input polygons. The input polygons must be in a geographic coordinate system.
Return type:
Number[]Parameters:
< |
Required | An array of polygons. |
< |
Required | The area unit. See Units for a list of valid values. |
Sample:
require([
"esri/geometry/geodesicUtils", "esri/units", ...
], function(geodesicUtils, Units, ... ) {
var areas = geodesicUtils.geodesicAreas([inputGeometry], esri.Units.ACRES);
...
});
Returns a densified geometry.
Return type:
GeometryParameters:
< |
Required | A polyline or polygon to densify. |
< |
Required | The maximum segment length in meters. |
Sample:
require([
"esri/geometry/geodesicUtils", ...
], function(geodesicUtils, ... ) {
var clientDensifiedGeometry = new geodesicUtils.geodesicDensify(geometry, 10000);
...
});
Determine the length for the input polylines using the specified length unit. The input polylines must be in a geographic coordinate system.
Return type:
Number[]Parameters:
< |
Required | An array of polylines. |
< |
Required | The length unit. See Units for a list of valid values. |
Sample:
require([
"esri/geometry/geodesicUtils", "esri/units", ...
], function(geodesicUtils, Units, ... ) {
var lengths = geodesicUtils.geodesicLengths([polyline], Units.KILOMETERS);
...
});
