Project (Image Service)

URL:: https://<imageservice-url>/project
Methods:: GET
Required Capability:: Image
Version Introduced:: 10.3

Description

This operation is supported at 10.3 and later. The project operation is performed on an image service resource. This operation projects an array of input geometries from the input spatial reference to the output spatial reference. The response order of geometries is in the same order as they were requested. The project operation supports projecting geometries to different spatial references. This operation supports spatial references represented in the Image coordinate system, which is not available through the project operation of a geometry service.

You can provide arguments to the project operation as query parameters defined in the following parameters table:

Request parameters

Parameter	Details
`geometries`	Specifies the array of geometries to be projected. The structure of each geometry in the array is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API. The `geometries` parameter is an array of input geometries. All geometries in this array should be of the type defined by `geometryType`. Syntax: Use dark colors for code blocksCopy `1 2 3 4 { "geometryType" : "<esriGeometryPoint \| esriGeometryMultipoint \| esriGeometryPolyline \| esriGeometryPolygon>" "geometries" : [ <geometry1>, <geometry1>, ..., <geometryN> ] }` Example: Use dark colors for code blocksCopy `1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 { "geometryType" : "esriGeometryPolyline", "geometries" : [ { "paths" : [ [[-117,34],[-116,34],[-117,33]], [[-115,44],[-114,43],[-115,43]] ] }, { "paths" : [ [[32,17],[31,17],[30,17],[30,16]] ] } ] }`
`inSR`	Specifies a well-known ID `wkid` of the spatial reference, an image coordinate system ID `icsid`, or a spatial reference JSON object for the input `geometries`. For a list of valid WKID values, see Using spatial references. An image coordinate system ID can be specified using `0:icsid`; for example, `0:64`. The extra `0:` is used to avoid conflicts with `wkid`
`outSR`	Specifies a well-known ID `wkid` of the spatial reference, an image coordinate system ID `icsid`, or a spatial reference JSON object for the output `geometries`. For a list of valid WKID values, see Using spatial references. An image coordinate system ID can be specified using `0:icsid`; for example, `0:64`. The extra `0:` is used to avoid conflicts with `wkid`
`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`	The response format. The default format is `html` . Values: `html` \| `json` \| `pjson`

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.
