Linear Spectral Unmixing

inputRaster

(Required)

The portal item ID, image service URL, cloud raster dataset, or shared raster dataset that will be added to the image collection. At least one type of input needs to be provided in the JSON object. If multiple inputs are given, the itemId takes priority.

Syntax: A JSON object describes the input raster.

inputRaster={"folderId": <portal folder id>}
inputRaster={"itemIds": [<portal item id>, <portal item id>, <portal item id>]}
inputRaster={"urls": [<image service url>, <image service url>, <image service url>]}
inputRaster={"uris": [<cloud raster uri or shared data path>, <cloud raster uri or shared data path>]}

outputName

(Required)

Output hosted image service properties. If the hosted image service is already created, the portal item ID or service URL can be given to the service tool. The output path of the raster dataset generated in the raster store will be used to update the existing service definition. The service tool can also generate new hosted image service with the given service properties. The output hosted image service is stored in raster store and shared on either the Raster Analysis Image Server or Image Hosting Image Server depending on the Enterprise configuration.

Syntax: JSON object describes the output raster. At least one type of input needs to be provided in the JSON object. If multiple inputs are given, the itemid takes priority.

inputSpectralProfile

(Required)

The spectral information for the different land cover classes. This should be specified in JSON format.

Syntax: JSON format.

Example

1
inputSpectralProfile={"EsriEndmemberDefinitionFile":0,"FileVersion":1,"NumberOfEndmembers":3,"NumberOfBands":7,"Endmembers":[{"ID":1,"Name":"urban","SpectralProfile":[88,42,48,38,86,115,59,10]},{"ID" : 2,"Name":"vegetation","SpectralProfile":[50,21,20,35,50,110,23,20]},{"ID":3,"Name":"water","SpectralProfile":[51,20,14,9,7,116,4,30]}]}

valueOption

(Optional)

List of options to define the output pixel values.

• SUM_TO_ONE —Class values for each pixel are provided in decimal format with the sum of all classes equal to 1. For example, Class1 = 0.16; Class2 = 0.24; Class3 = 0.60 .
• NON_NEGATIVE —There will be no negative output values.

Syntax: A list representing the value option.

Example

1
valueOption=[“SUM_TO_ONE”, “NON_NEGATIVE”]

context

(Optional)

Contains additional settings that affect task execution. This task has the following settings:

• Extent: A bounding box that defines the analysis area.
• Output Spatial Reference
• Snap Raster
• Cell Size
• Parallel Processing Factor

f

The response format. The default response format is html.

Values: html | json
