Dictionary renderer with graphics overlay

Create graphics from an XML file with key-value pairs for each graphic, and display the military symbols using a MIL-STD-2525D web style in 2D.

Use case

Use a dictionary renderer on a graphics overlay to display more transient data, such as military messages coming through a local tactical network.

How to use the sample

Pan and zoom to explore military symbols on the map.

How it works

1. Create a new DictionarySymbolStyle using a MIL-STD-2525D dictionary web style.
2. Create a new DictionaryRenderer from the dictionary symbol style.
3. Create a new GraphicsOverlay.
4. Set the dictionary renderer to the graphics overlay.
5. Parse through the XML and create a graphic for each element.
6. Use the _wkid key to get the geometry's spatial reference.
7. Use the _control_points key to get the geometry's shape.
8. Create a geometry using the shape and spatial reference from above.
9. Create a Graphic for each attribute, utilizing it's defined geometry.
10. Add the graphic to the graphics overlay.

Offline data

This sample uses the MIL-STD-2525D XML Message File hosted on ArcGIS Online.

About the data

The dictionary symbol style in this sample is constructed from a portal item containing a MIL-STD-2525D symbol dictionary web style. This ArcGIS Web Style is used to build custom applications that incorporate the MIL-STD-2525D symbol dictionary. This style supports a configuration for modeling locations as ordered anchor points or full geometries.
