Label 3D point data by a field in a layer property or by specifying a plug-in image path. This feature is available only for 3D point datasets. The specific operation steps are as follows:

1. Click the Scene-Thematic Map button to pop up the Thematic Map Settings panel.



2. In the panel, select a specific point data layer from the Layer Selection drop-down menu.
3. Select the specified field from the Associated Fields drop-down menu. All values for the selected field are displayed in the attribute sheet.
4. Set the annotation object type by checking Text or Picture. When you select text, you can modify each attribute value in the attribute sheet as needed. When a picture is selected, you can enter the absolute path of the specified picture at each attribute value as needed to label the point data to show the unspecified picture.
5. You can check whether to cluster according to your needs. Clustering indicates whether the data in the layer is clustered according to the set value when zooming the scene. Specific parameters include:
• Cluster Spacing: Indicates the screen pixel spacing between two point objects, points within a set value range display clusters as the first point within the range in pixels, default is 80.
• Minimum Number of Clusters: Indicates the minimum number of point objects displayed in the scene, in units, the default is 3.
6. After setting the parameters, click OK to add a thematic map effect to the scene. Clicking Cancel clears the theme effect from the scene.
