The Extract Data task is used to extract data from one or more layers within a given extent. The extracted data format can be CSV, KML, a file geodatabase, or a shapefile. File geodatabases and shapefiles are added to a .zip file that can be downloaded.
A list of input layers to be extracted.
Syntax: As described in detail in the Feature Input topic, this parameter can be one of the following:
The area of interest used to extract the input features.
The extent can also be set using the extent option for the context parameter. The default processing extent is the full extent of the dataset.
If an extent layer is used, the features that are extracted must be within the extent of both the extent layer and the processing extent. If no extent layer is selected, the extent will be based solely on the processing extent.
Syntax: As described in detail in the Feature input topic, this parameter can be one of the following:
A Boolean value that specifies whether the features in the input layer are clipped within the extent parameter. By default, features are not clipped and all features intersecting the extent are returned. The default is false.
Values: true | false
A keyword defining the output data format for the extracted data.
Values: FILEGEODATABASE | SHAPEFILE | KML | CSV
The default is CSV.
If FILEGEODATABASE is specified, and the input layer has attachments, the attachments are extracted to the output file geodatabase if clip is false. If clip is true, attachments are not extracted.
The name of the item on your My contents page. For more information on these item properties, see the Item resource page in the ArcGIS REST API.
The Context parameter contains the following additional settings that affect task operation:
The response format. The default response format is html.
Values: html | json
When you submit a request, the service assigns a unique job ID for
"jobId": "<unique job identifier>",
"jobStatus": "<job status>"
Checking 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 Checking 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:
When the status of the job request is esriJobSucceded, you can access the results of the analysis by making a request of the following form:
http://<analysis url>/ExtractData/jobs/<jobId>/results/contentID?token=<your token>&f=json
The result has properties for parameter name, data type, and value.
The value property contains the item ID and a URL to the item.
