- URL:https://<rasteranalysis-url>/ClassifyObjectsUsingDeepLearning
- Version Introduced:10.8
Description
The ClassifyObjectsUsingDeepLearning task is used to classify objects based on overlaid imagery data using the designated deep learning model and generate a feature service with a new assigned label for each object.
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 input image used to classify objects. This can be specified as the portal item ID, image service URL, cloud raster dataset, shared raster dataset, a feature service with image attachments, or a raster dataset or image collection in the data store. At least one type of input must be provided in the JSON object. If multiple inputs are provided, the itemId value takes priority. Syntax: A JSON object describes the input raster. Example:
|
inputFeatures (Optional) | The feature service layer that contains the points, polylines, or polygons that identify the location of each object to be classified and labeled. The layer index is needed for the feature service URL. Syntax: A JSON object describes the input feature service layer. Example:
Example
|
outputFeatureClass (Required) | The output hosted feature service properties. If you're using an existing hosted feature service, the portal item ID or service URL can be provided, and the output path of the feature class that is generated will be used to update the existing service definition. The service tool can also generate a new hosted feature service with the service properties provided. The output hosted feature service is stored and shared on the hosting server. Syntax: A JSON object describes the output feature service. Example:
|
model (Required) | The deep learning model used to classify objects. This can be specified as the deep learning model portal item ID, as an .emd or .dlpk file, or as the entire JSON string of the model definition. Syntax: A JSON object describes the model. Example:
Example for JSON:
|
modelArguments (Optional) | The name of the value pairs of arguments and their values that can be customized by the clients. Syntax: A JSON object describes the value pairs of arguments. Example:
|
classLabelField (Optional) | The name of the field that will contain the classification label in the output feature service. Syntax: String. Example:
|
processAllRasterItems (Optional) | Specifies how all raster items in an image service will be processed. If set to true, all raster items in the image service will be processed as separate images. If set to false, all raster items in the image service will be mosaicked together and processed. This is the default. Values: true | false Example:
|
context (Optional) | The environment settings that affect task execution. This task has the following settings:
Example
|
f | The response format. The default response format is html. Values: html | json |

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://<rasterAnalysisTools-url>/AddImage/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://<rasterAnalysisTools-url>/AddImage/jobs/<jobId>/results/outObjects
JSON Response example
The response returns the outObjects output parameter, which has properties for parameter name, data type, and value. The content of value is always the output feature layer item ID and the image service URL.
