A Web Map Tile Service (WMTS) raster tile is a global layer in 3D City Builder that supports independent style and data configurations. This topic describes the configuration items for the WMTS raster tile layer, including its general and graphics settings.
In the layer list on the left side of the scene editor, click the WMTS Raster Tile layer to open the configuration panel, where you can configure the WMTS Raster Tile layer's style and data.
This widget is exclusive to the DataV Premium Edition. You must upgrade to use this widget.
If the layer list does not contain WMTS Raster Tile, you must add the WMTS Raster Tile layer. For more information, see Add a sub-widget.

Search Configuration: To quickly find a specific configuration item, click on the Configuration panel in the upper right corner and enter the item's name in the Search Configuration field. The system utilizes a fuzzy match to assist in locating items. For more information, see search configuration items.
General
Parameter
Description
Rendering Order
Set the rendering order of the WMTS raster tile. A larger value brings the tile to the front.
Graphics
Parameter
Description
Transparency
Drag the slider to set the opacity of the WMTS raster tile. The value ranges from 0 to 1.

Data panel
Parameter |
Description |
url |
The service endpoint for the WMTS raster tile. |
projType |
The projection type of the WMTS raster tile. |
activeLayer |
The layer name of the WMTS raster tile. |
headers |
The request header for the WMTS raster tile. |
customParameters |
The service parameters for the WMTS 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 on the left of the Scene Editor, click the
icon to the right of WMTS Raster Tile.Click the
icon in the upper-left corner of the page.On the blueprint editor configuration page, click the WMTS raster tile layer in the import node bar. Its configuration parameters are displayed on the canvas, as shown in the following figure.
Events
Event
Description
When Data Request is Complete
An event that is triggered after the data API request is returned and processed by the filter. The event also returns the processed data in JSON format. 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
Requests data from the server again. 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 WMTS raster tile is set to
https://api.testand the data passed to the Request Data action is{ id: '1'}, the final request URL ishttps://api.test?id=1.Import Data
After processing the data into the format required by the component, you can import it to redraw the component. You do not need to request data from the server-side again. For specific data examples, see the Data tab in the Data Response Result area of the configuration panel on the right side of the canvas editor.
