| Property | Details |
|---|---|
| drawingInfo.labelingInfo[] | An array of labelingInfo objects. |
| drawingInfo.renderer | The renderer object contains the drawing information for the operationalLayer. |
| elevationInfo | Elevation info defines how features are aligned to ground or other layers. |
| maxScale | Represents the maximum scale (most zoomed in) at which the layer is visible in the view. If the web scene is zoomed in beyond this scale, the layer will not be visible. A value of 0 means the layer does not have a maximum scale. If set, the maxScale value should always be smaller than the minScale value, and greater than or equal to the service specification. |
