The XYZ raster tile is a global layer in 3D City Builder. It supports independent style and data configurations, including general configurations and graphic styles. This topic describes the configuration items of the XYZ raster tile layer.
In the Layers list on the left side of the Scene Editor, click the XYZ Raster Tile layer to open the Configuration Panel and configure the style and data of the XYZ Raster Tile layer.
This widget is available only to users of DataV Professional Edition or later. To use this widget, you must upgrade DataV to the Professional Edition or a later version.
If XYZ Raster Tile is not in the layer list, you need to add the XYZ Raster Tile layer. For more information, see Add Child 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

Data panel
Parameter |
Description |
url |
The URL of the XYZ raster tile template. |
projType |
The projection type of the XYZ raster tile. |
minZoom |
The minimum zoom level of the XYZ raster tile. |
maxZoom |

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 Scene Editor, click the
icon to the right of XYZ Raster Tile in the Layers list.Click the
icon in the upper-left corner of the page.On the Blueprint Editor configuration page, click the XYZ raster tile layer in the Import Nodes pane. The configuration parameters for the XYZ raster tile appear on the canvas, as shown in the following figure.
Events
Event
Description
When a Data API Request is Complete
This event is triggered after the data API request is returned and processed by the filter. The processed data in JSON format is also thrown. For a data example, see the Data Response Result area on the Data tab of the widget's configuration panel on the right of the canvas editor.
Actions
Action
Description
Request data API
Requests server-side data again. Data output from an input data processing node or a layer node is used as a parameter. For example, if an XYZ tile layer is configured with an API data source of
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
Process the data in the component format and import it to redraw the component. This action does not require a new request for server-side data. For data examples, see the Data tab and view the Data Response area in the configuration panel of the canvas editor.
Show component
Shows the component. No parameters are required.
Hide component
Hides the component. No parameters are required.
