Configuration file for the Data Extract widget

The general structure of the the Data Extract widget configuration file is shown by the conceptual graphic below.

The file is defined by a <configuration> tag that identifies it as a configuration file for the Viewer. It supports defining the geoprocessing service and the method of defining the data extract area of interest. It has the following child tags:

<dataextractionservice>

URL to the geoprocessing service where data will be extracted from. This should be a geoprocessing service based on the Data Extract task.

<useproxy>

Enables the widget to use a proxy server for data layers. If this is set to "true", the widget will use the proxy server specified by the <httpproxy> tag in the Viewer application configuration file. Learn more about using a proxy page.

<aioselectionmethod>

Defines how the area of interest is set. Valid values are "extent" and "draw". The "extent" option will use the current map extent as the area boundary to extract data from. When set to "draw", end users define the area of interest (AOI) to extract from with the area boundary creation tools.

<excludelayer>

When a layer is specified, it will not display in the Data Extract widget, and therefore will not be downloadable. Multiple <excludelayer> tags can be specified to exclude multiple layers.

Labels

In addition, the configuration file also supports changing the labels used in the widget dialog (this is not shown in the conceptual graphic).

<labels>

Container for labels that can be modified in this widget. It has many child tags:
