Catalog layers can be created by referencing a feature service layer where the type is a 'Catalog Layer'. Catalog Layer helps visually explore the footprints of disperate layer types stored as references along with footprint in shape field and other attributes relavent to each layer reference.

Properties
| Property | Details |
|---|---|
| blendMode | Blend modes are used to create various effects by blending colors of top and background layers. normal blend mode is the default.Valid values: average, color, color-burn, color-dodge, darken, destination-atop, destination-in, destination-out, destination-over, difference, exclusion, hard-light, hue, invert, lighten, lighter, luminosity, minus, multiply, normal, overlay, plus, reflect, saturation, screen, soft-light, source-atop, source-in, source-out, vivid-light, xor |
| customParameters | A sequence of custom parameters appended to the URL of all requests related to a layer. |
| dynamicGroupLayer | Object representing the dynamic group layer that loads layers selectively based on the current map extent, their scale visibility, time and range. |
| effect | Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work. |
| footprintLayer | Object representing the dynamic group layer to visualize the catalog layer items as a polygon feature layer. |
| id | A unique identifying string for the layer. |
| itemId | Optional string containing the item ID of the service if it's registered on ArcGIS Online or your organization's portal. |
| layerDefinition | A layerDefinition object defining the attribute schema and drawing information for the layer. See layerDefinition properties table. |
| layerType | String indicating the layer type. Valid value of this property CatalogLayer |
| opacity | The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency. |
| refreshInterval | Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled. |
| timeAnimation | Indicates whether to disable time animation if the layer supports it. |
| title | A user-friendly string title for the layer that can be used in a table of contents. |
| url | The URL to the layer. |
| visibility | Boolean property determining whether the layer is initially visible in the web map. |
| visibilityTimeExtent | Represents time extent that will control when a layer should be visible based on webmap's current time. Visibility time extent only affects the layer visibility and will not filter the data. |
layerDefinition properties
| Property | Details |
|---|---|
| definitionExpression | SQL-based definition expression string that narrows the data to be displayed in the layer. |
| displayFilterInfo | Display filters provide information about which features should be rendered on the display. |
| maxScale | Integer property used to determine the maximum scale at which the layer is displayed. |
| minScale | Integer property used to determine the minimum scale at which the layer is displayed. |
| orderBy[] | An array of orderByField objects specifying the feature display order. Features can be sorted in ascending or descending order of a numeric or date field only. If ascending, features with smaller values will be drawn on top of features with larger values. For date values, ascending order means features with older dates will be drawn on top of features with recent dates. If descending, the sort behavior is reversed. Only one field can be specified at this time. When this property is not defined, features are displayed in the order in which they are received by the client. |
