Description
The FindArgumentStatistics task is used to extract the dimension value or band index at which a given statistic is attained for each pixel in a multidimensional or multiband raster.
License:
As of 10.8, you must license your ArcGIS Server as an ArcGIS Image Server to use this resource.Request parameters
Parameter | Details |
---|---|
inputRaster (Required) | The portal folder ID, portal item ID, image service URL, cloud multidimensional or multi-band raster dataset or shared multidimensional or multi-band raster dataset that will be added to the image collection. At least one type of input needs to be provided in the JSON object. Syntax: A JSON object describes the input raster.
|
outputName (Required) | The output image collection name or URL. The image service must exist before you add the images. 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: A JSON object describes the output multidimensional or multiband raster. NOTE: Set "image,metadata" as image service capabilities to make sure the output image service can be recognized as multidimensional by other raster analysis tools. Example: |
dimension (Optional; Required if inputRaster is multidimensional) | The dimension from which the statistic will be extracted. Syntax: A string representing the dimension name. Example
|
dimensionDefinition (Optional) | Specifies the dimension interval for which the data will be analyzed.
Syntax: A string of one of the keywords. Example
|
intervalKeyword (Optional; Required when dimension is StdTime and dimensionDefinition is INTERVAL_KEYWORD) | Specifies the keyword interval that will be used when analyzing along the dimension.
Syntax: A string of one of the keywords. Example
|
variables (Optional) | The variable or variables to be analyzed. If the input raster is not multidimensional, the pixel values of the multiband raster are considered the variable. If the input raster is multidimensional and no variable is specified, all variables with the selected dimension will be analyzed. For example, to find the years in which temperature values were highest, specify temperature as the variable to be analyzed. If you do not specify any variables and you have both temperature and precipitation variables, both variables will be analyzed and the output multidimensional raster will include both variables. Syntax: A list containing the variables. Example:
|
statisticsType (Optional) | The statistic to extract from the variable or variables along the given dimension.
Syntax: A string of one of the keywords. Example:
|
minValue (Optional; Required when statisticsType is DURATION) | The minimum variable value to be used to extract the duration. Syntax: A double value. |
maxValue (Optional; Required when statisticsType is DURATION) | The maximum variable value to be used to extract the duration. Syntax: A double value. |
multipleOccurrenceValue (Optional) | The pixel value to use to indicate that a given argument statistic was reached more than once in the input raster dataset. If not specified, the pixel value will be the value of the dimension the first time the argument statistic is reached. Syntax: An integer. Example:
|
ignoreNoData (Optional) | Specifies whether NoData values are ignored in the analysis.
Syntax: A Boolean value as either true or false Example:
|
context (Optional) | Contains additional settings that affect task execution. This task has the following settings:
|
f | The response format. The default response format is html. Values: html | json |
Example usage
Below is a sample request URL for FindArgumentStatistics:
https://services.myserver.com/arcgis/rest/services/System/RasterAnalysisTools/GPServer/FindArgumentStatistics
Response
When you submit a request, the task assigns a unique job ID for the transaction.
Syntax:{ "jobId": "<unique job identifier>", "jobStatus": "<job status>" }
After the initial request is submitted, you can use the jobId to periodically check the status of the job and messages, as described in Check job status. Once the job has successfully completed, use the jobId to retrieve the results. To track the status, you can make a request of the following form:
https://<analysis-url>/FindArgumentStatistics/jobs/<jobId>
When the status of the job request is esriJobSucceeded, you can access the results of the analysis by making a request of the following form:
https://<rasteranalysis-url>/FindArgumentStatistics/jobs/<jobId>/results/result/outputRaster?token=<yourtoken>&f=json

JSON Response example
The response returns the results output parameter, which has properties for parameter name, data type, and value. The content of value is always the image service URL.
