Query Boundary

URL:: https://<imageservice-url>/queryBoundary
Methods:: GET
Required Capability:: Image
Version Introduced:: 10.6

Description

The Query Boundary operation is performed on an image service resource.

The Query Boundary operation is supported by image services based on mosaic datasets or raster datasets.

For an image service based on a mosaic dataset, the result of this operation includes the geometry shape of the mosaicked items' boundary and area of coverage in square meters.

For an image service based on a raster dataset, the result of this operation includes the geometry shape of the dataset's envelope boundary and area of coverage in square meters.

Request parameters

Parameter Details

Parameter	Details
`f`	Description: The response format. The default response format is HTML. Values: `html \| json`
`outSR`	Description: The spatial reference of the boundary's geometry. The spatial reference can be specified as either a well-known ID or as a spatial reference JSON object. If the outSR is not specified, the boundary will be reported in the spatial reference of the image service.
`datumTransformation`	A WKID or a JSON object specifying the geographic datum transformation. Use it to apply a single datum transformation or a composite datum transformation chain to the exported image when the geographic datum of imageSR is different than the geographic datum of image service's spatial reference. When not specified, a default datum transformation will be applied if needed.

f

Description: The response format. The default response format is HTML.

Values: html | json

outSR

Description: The spatial reference of the boundary's geometry.

The spatial reference can be specified as either a well-known ID or as a spatial reference JSON object.

If the outSR is not specified, the boundary will be reported in the spatial reference of the image service.

datumTransformation

A WKID or a JSON object specifying the geographic datum transformation. Use it to apply a single datum transformation or a composite datum transformation chain to the exported image when the geographic datum of imageSR is different than the geographic datum of image service's spatial reference. When not specified, a default datum transformation will be applied if needed.

Datum transformation information

While specifying transformation, you need to think about which datum transformation is most applicable to project the image service to the imageSR. The spatialReference property of the image service resource reports which spatial reference is used by the service. For a list of valid datum transformation ID values (WKID) and well-known text (WKT) strings, see Using spatial references. For more information on datum transformation, see the transformation parameter in the Project operation.
