Description:

Provides the structure for setting up parameters for shapefiles generated with the Extract Server.

Restrictions:

None

Notes:

In order to allow GET_EXTRACT requests on an ArcIMS service, the extract EXTENSION must be included in the map configuration file with at least one layer. As part of the extension, EXTRACTPARAMS is required and OUTPUTFILE and OUTPUTFIELD are optional.
In order to allow clipping for a layer in a map configuration file, EXTENSION and EXTRACTPARAMS must be included, and clip must be set to "true".
For more information on using the Extract Server, see Using GET_EXTRACT and EXTRACT.

Attribute	Usage	Back to Top
clip	Determines whether features are clipped at the current extent boundary in the viewer. If no clipping is used, features partially within the envelope are extracted in their entirety. If clipping is used, features are extracted based on the current extent boundary. Note that none of a layer's database values are prorated for any clipped features.
