Description:

Sends a request to the Extract Server. Layers are extracted into shapefile format and and placed in a ZIP file.

Restrictions:

• Only vector data sets can be extracted. This includes shapefiles and ArcSDE layers. The layers can be extracted from a MapService or from dynamic vector layers in the GET_EXTRACT request. Image and acetate layers cannot be extracted.

Notes:

• See EXTRACT for response.
• In order for GET_EXTRACT to work on a MapService, the map configuration file must have at least one layer that includes an Extract EXTENSION. For example:
  
            <EXTENSION type="extract" >
              <EXTRACTPARAMS clip="true" />
            </EXTENSION>
  
  
• Extract requests must be routed to the Extract Server. This routing information is contained in the URL sent to the ArcIMS site such as in the following example (all one line):
  http://myComputer.domain.com/servlet/com.esri.esrimap.Esrimap?ClientVersion=3.1
          &ServiceName=myservice
          &CustomService=Extract
          &Form=True&Encode=True
• See Using GET_EXTRACT and EXTRACT for more information and additional examples.
