Export Widget for CMV

  1. Export attributes in tabular formats from the Attributes Table widget or other widgets that have a dgrid. Formats supported:

    • Excel (xlsx and xls)
    • Comma-Separated-Values (csv)
  2. Export features in spatial formats. Formats supported:

    • Esri Shapefiles
    • KML
    • KMZ
    • GeoJSON
    • TopoJSON
    • Well-Known Text (wkt)
  3. Examples of exported features:

    • Features from the Attributes Table widget
    • An Identified Feature
    • Features from a Feature layer on the map
    • Graphics from a Graphics layer on the map
    • Drawn Graphic Shapes from a Draw widget
    • Features return from a QueryTask or FindTask of a Map Service
    • A FeatureSet returned from a Geoprocessing Task

All geometries exported to GeoJSON or KML are projected to Lat/Lng using Spatial Reference 4326. When exporting to Well-Known Text or Esri Shapefile, an output Spatial Reference WKID can be provided and the geometries are projected to the selected Spatial Reference.

NOTE: Downloading the export file when using Internet Explorer 9 or older is not supported.

Communicating with other widgets

The Exports widget does not stand-alone. It is intended with to be used as a querying interface for an attributes table. Two other widgets are planned that can communicate with an attributes table:

  1. Plug-in for layerControl widget
  2. Query Builder widget

Communication to/from another widget to an attributes table is via dojo's topic publish/subscribe model. The available topics are listed below.


Export Topics

Subscribed Topics

The Export widget subscribes to the following topics.

// open the widget
'exportWidget/openDialog'

// export attributes or features without opening the dialog
'exportWidget/export'
