Generate Raster

rasterFunction

(Required)

Performs analysis on the input raster dataset. The value can be a string keyword for predefined raster functions such as NDVI, a JSON object that describes a raster function chain with built-in functions that are recognized by the server, or the contents of a raster function template file (*.rft.xml) . See the complete list of raster analysis functions you can execute on a distributed server.

outputName

(Required)

The location where the service will generate the output raster.

Syntax: A JSON object describes the output raster.

Example:

//Portal Item ID
{"itemId": <portal item id>}

//Image Service URL
{"url": <image service url}

//Service Properties
{"serviceProperties":{"name":"testrasteranalysis",
  "serviceUrl":"https://<server name>/server/rest/services/Hosted/testrasteranalysis/ImageServer"},
  "itemProperties":{"itemId":"8cfbd3ec25584d0d8f4ed23b8ff7c43b", "folderId", "sdfwerfbd3ec25584d0d8f4",: }}

functionArguments

The JSON string that specifies the raster function argument value. This parameter is optional because the argument value can also be defined in the function template. The rasterArguments parameter supports the RasterInfo argument for all raster functions. The information stored in RasterInfo allows you to specify the output raster dataset's properties such as cell size, extent, and nodata value.

}

outputRasterProperties

Sets the output raster's key metadata properties.

{"SensorName": "Landsat 8", "CloudCover": 20}

context

Contains the additional setting Output Spatial Reference (outSR ), which specifies where the output will be projected in the output spatial reference.

{"outSR": {spatial reference}}

f

The response format. The default response format is html.

Values: html | json
