Static Layer Support

Supported static layer in RAMP

RAMP can display a feature layer as a static (non interactive) layer. It will display as an non-interactive layer on the map, and will appear in the layer selector. Layer visibility and opacity can be adjusted. Static layers can be re-ordered amongst any other feature layer. The static layer must support a projection that is compatible with the basemap being used.

Clicking the static layer will not return any information, no maptip or anchored maptip will be displayed. Features of a static layer do not appear in the data grid.

Think of a static layer as an enhancement to the basemap tile. It provides extra contextual information to the map, but is not considered to provide feature data.

Config a static layer

Static layer config is added in the featureLayers section just like regular feature layer with additional config values. The following is an example of static layer config setting:

{
	"id":"oilSandsRegions",
	"displayName":"Oil Sands Regions",
	"url":"http://somedomain.com/ArcGIS/rest/services/OilSandsRegions/MapServer/0",		
	"symbology":{
		"icons":{
			"default":{
				"imageUrl":"assets/images/icons/oil-128-128.png",
				"legendText":"Oil Sands Regions"
			}
		}
	},
	"isStatic":true
}

Please note the above mentioned config settings are the required attributes for a static layer, any extra information is not used.

• symbology This information is used to generate legend information with the imageUrl and legendText.
• isStatic The isStatic attribute is used by RAMP to identify the layer as static; which in turn unsubscribe to the event handlers for maptip display and datagrid generation.

Please refer to JSON Config Definition for more information on RAMP config settings.
