Update Raster (Operation)
URL http://<imageservice-url>/update (POST only)
Parent Resource Image Service
Required Capability Edit

Description

This operation is supported from 10.1 onwards.

The update raster operation is performed on an image service resource.

The update raster operation updates rasters (attributes, footprints, or replace existing raster files) in an image service (POST only).

In most cases, this operation is used to update attributes or footprints of existing rasters in an image service. In certain cases if the original raster need to be replaced, the new raster can either be items uploaded using the items parameter; or URLs of published services using the serviceUrl parameter.

Instead, if the serviceUrl is specified, the image service will add this URL to the mosaic dataset. The serviceUrl is required input for the following raster types: Image Service, Map Service, WCS and WMS.

You can provide arguments to the update raster operation as query parameters defined in the parameters table below.

Parameters

Parameter Details
f Description: The response format. The default response format is html.

Values: html | json
rasterId Required
Description: The object ID of the raster catalog item to be updated.

Syntax: rasterId=<rasterId>

Example: rasterId=3
itemIds Description: The uploaded items (raster files) being used to replace existing raster.

Syntax: itemIds=<itemID1>,<itemID2>

Example: itemIds=ib740c7bb-e5d0-4156-9cea-12fa7d3a472c,ib740c7bb-e2d0-4106-9fea-12fa7d3a482c

serviceUrl Description: The URL of the service to be uploaded to replace existing raster data. The image service will add this URL to the mosaic dataset. Service url is required for the following raster types: Image Service, Map Service, WCS and WMS

Example: serviceUrl=http://myserver/arcgis/services/Portland/ImageServer
computeStatistics Description: If true, statistics for the uploaded raster will be computed. The default is false.

Values: false | true
buildPyramids Description: If true, build pyramids for the uploaded raster. The default is false.

Values: false | true
buildThumbnail Description: If true, generate a thumbnail for the uploaded raster. The default is false.

Values: false | true
minimumCellSizeFactor Description: The factor (times raster resolution) used to populate MinPS field (maximum cell size above which raster is visible).

Syntax: minimumCellSizeFactor=<minimumCellSizeFactor>

Example: minimumCellSizeFactor=0.1
maximumCellSizeFactor Description: The factor (times raster resolution) used to populate MaxPS field (maximum cell size below which raster is visible).

Syntax: maximumCellSizeFactor=<maximumCellSizeFactor>

Example: maximumCellSizeFactor=10
footprint Description: A JSON 2D polygon object that defines the footprint of the raster. If spatial reference is not defined, it will be default to image service's spatial reference.

Syntax and Examples:

JSON Structures:

Syntax: 
 <polygon>

Example: 

{
"rings" : [ 
 [ [-97.06138,32.837], [-97.06133,32.836], [-97.06124,32.834], [-97.06127,32.832], [-97.06138,32.837] ], 
 [ [-97.06326,32.759], [-97.06298,32.755], [-97.06153,32.749], [-97.06326,32.759] ]
],
"spatialReference" : {"wkid" : 4326}
}
attributes Description: Any attribute for the uploaded raster.

Syntax: 
{
  "<name1>" : <value1>,
  "<name2>" : <value2>
}


Example: 
{
  "Year" : 2002,
  "State" : "Florida"
}
geodataTransforms Description: The geodata transformations applied on the updated rasters. A geodata transformation is a mathematical model that performs geometric transformation on a raster, it defines how the pixels will be transformed when displayed or accessed, such as polynomial, projective or identity transformations. The geodata transformations will be applied to the dataset updated. Below is the JSON representation of transformations:

Syntax: 
[
  {
  "geodataTransform" : "<geodataTransformName1>",
  "geodataTransformArguments" : {<geodataTransformArguments1>}
  },
  {
  "geodataTransform" : "<geodataTransformName2>",
  "geodataTransformArguments" : {<geodataTransformArguments2>}
  }
]

The syntax of the geodataTransformArguments property varies based on the specified geodataTransform name. Please refer to the Geodata Transformations documentation for more details.
geodataTransformApplyMethod Description: This parameter defines how to apply the provided geodataTransform. The default is esriGeodataTransformApplyAppend.

Values: esriGeodataTransformApplyAppend | esriGeodataTransformApplyReplace | esriGeodataTransformApplyOverwrite

Example Usage

Update raster visibility and some other attributes by specifying the following post request content: 
rasterId=10&attributes={"MinPS":0,"MaxPS":10,"GroupName":"LAS"}
Update an image's georeferencing by providing the following post request content: 
rasterId=10&geodataTransforms=[{"geodataTransform" : "Polynomial","geodataTransformArguments" : {"sourcePoints" : [{"x":0, "y":0}, {"x":100, "y":0},{"x":100, "y":100}],"targetPoints" : [{"x":10, "y":10}, {"x":110, "y":10},{"x":110, "y":110}],"polynomialOrder" : 1,"spatialReference": {"wkid" : 54004}}}]&geodataTransformApplyMethod=esriGeodataTransformApplyAppend&f=json
