The SuperMap REST raster tile is a global layer in 3D City Builder. It supports independent style and data configurations, including general, graphic, and interaction settings. This topic describes the configuration items for the SuperMap REST raster tile layer.
In the layer list on the left side of the scene editor, click the SuperMap REST Raster Tile layer to open the configuration panel, where you can configure the style and data of the SuperMap REST Raster Tile layer.
This widget is available only to users of DataV Premium Edition. To use this widget, you must upgrade to the Premium Edition.
If SuperMap REST Raster Tile is not in the layer list, this means that the SuperMap REST Raster Tile layer has not been added. For more information, see Add a sub-widget.

General
Parameter
Description
Rendering Order
Sets the rendering order of the SuperMap REST raster tile layer.
Graphic
Parameter
Description
Transparency
Drag the slider to set the opacity coefficient of the SuperMap REST raster tile layer. The value ranges from 0 to 1.
HSB Adjustment

Interaction
Parameter
Description
Server-side interaction
Turn on the switch to enable server-side interaction for the SuperMap REST raster tile layer. Turn off the switch to disable it.
Data panel
Parameter |
Description |
url |
The service endpoint of the SuperMap REST raster tile. |
projType |
The projection type of the SuperMap REST raster tile. |
scale |
The scale of the SuperMap REST raster tile. |
customParameters |
The service parameters of the SuperMap REST raster tile. |
Configuration Item |
Description |
Controlled Mode |
Turn on the switch to prevent the widget from requesting data upon initialization. Data is requested only through a callback ID or a method configured in the blueprint editor. Turn off the switch to allow automatic data update requests. The switch is off by default. |
Automatic Update Request |
Select this option to enable dynamic polling and manually set the polling frequency. If you clear this option, data is not updated automatically. You must manually refresh the page or trigger data update requests using the blueprint editor or callback ID events. |
Data Source |
Click Configure Data Source. In the Set Data Source panel, you can modify the data source type and data query code, preview the data source return results, and view the data response. |
Data Result |
Displays the response result of a data request. When the data source changes, click the |
icon on the right to view the real-time data response.You can also use the layer data API as a block data API to configure more data source types in the data dashboard or to interact with data from common chart widgets. For more information, see One-click generation of block APIs.
If you created your 3D City Builder project in Spatial Data Project mode and the project contains data primitive layer content, you can use the Spatial Build Data Source to obtain spatial map data when you configure the data panel in the scene editor. The steps are as follows:
In the layer configuration panel, select the Data tab. Click the Data Source Type drop-down list at the bottom of the panel and select Spatial Build Data Source.
From the Data Project drop-down list at the bottom of the panel, select an existing data project from the spatial build platform.
After you select a data project, select a matching dataset from the Dataset drop-down list.
NoteIf no configurable data types are available for the Data Project and Dataset configuration items, click Go to Spatial Build Platform to Manage Data in the panel to configure data in the spatial build platform. For more information, see Overview of spatial data management.
Blueprint interaction
In the layer list of the scene editor, click the
icon next to SuperMap REST Raster Tile.Click the
icon in the upper-left corner of the page.On the Blueprint Editor configuration page, click the SuperMap REST raster tile layer in the Imported Nodes pane. The configuration parameters for the SuperMap REST raster tile layer appear on the canvas, as shown in the following figure.
Events
Event
Description
When Data Request Is Complete
This event is triggered after a data API request is returned and processed by a filter. The processed data in JSON format is also returned. For a data example, see the Data Response section on the Data tab of the widget's configuration panel in the canvas editor.
Actions
Action
Description
Request Data API
Re-requests data from the server-side. Data from an input data processing node or a layer node is used as a parameter. For example, if the API data source for the SuperMap REST raster tile layer is set to
https://api.testand the data passed to the Request Data API action is{ id: '1'}, the final request URL ishttps://api.test?id=1.Import Data API
After you process the data in the component's rendering format, you can import the component to redraw it. You do not need to request server-side data again. For a data example, see the Data Response area on the Data tab of the configuration panel to the right of the component in the canvas editor.
