Description
The label
operation is performed on a geometry service resource. The label
operation calculates an interior point for each polygon specified in the input array. These interior points can be used by clients for labeling the polygons. This operation calls simplify
on the input polygons
. You can provide arguments to the label
operation as query parameters defined in the following parameters table.
Request parameters
Parameter | Details |
---|---|
| Specifies the array of polygons whose label points are to be computed. The spatial reference of the polygons is specified by Syntax
Example
For a large set of geometries, you can specify a URL to the input geometries stored in a JSON structure in a file on a public server. The expected format of the file's contents will be the same as that expected if the polygons were directly embedded in the request. URL-based syntax

| Specifies the well-known ID (WKID) of the spatial reference or a spatial reference JSON object for the input |
| The response format. The default response format is Values: |
Example usage
The following is a sample request URL for label
that computes a label point within the input polygon:
https://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/Geometry/GeometryServer/labelPoints?sr=4326&polygons=[{"rings":[[[-105,34],[-104,34],[-104,35],[-105,35],[-105,34]]]}]
JSON Response syntax
{
"labelPoints": [<point1>, <point2>, ..., <pointN>]
}
