2D to 3D Data Conversion
Through type conversion, 2D datasets (points, lines, regions) can be converted into 3D datasets (points, lines, regions).
When converting 2D datasets to 3D datasets, original fields and attributes are preserved. Additionally, a Z field (elevation information) will be added to the data objects' corresponding nodes. For viewing nodes of selected objects, see Query and Modify Object Properties.
When converting point datasets to 3D point datasets, a Z field will be added under the data object's node, and an elevation field (SMZ) will be created in the dataset properties table.
Load the converted 3D data into a scene for display. In the Layer Properties tab, set Height Mode to non-ground-following mode, then 3D objects will display point heights according to their Z-coordinate values.
This section uses 2D line-to-3D line conversion as an example to demonstrate feature entries and steps for 2D-to-3D data conversion.
Feature Entry
- Data tab -> Data Processing group -> Type Conversion -> 2D Line to 3D Line.
- Toolbox -> Type Conversion -> 2D-3D Conversion -> 2D Line to 3D Line.
Steps
- Click 2D Line to 3D Line, then set the source dataset, resulting dataset name and target datasource in the dialog box.
- Select the field containing elevation values, or left-click the Z-coordinate input box to manually set elevation values. Line data requires start and end elevation values; point and region data only need single elevation values.
- Execute the conversion after completing settings.
3D to 2D Data Conversion
Through type conversion, 3D datasets (points, lines, regions) can be converted into 2D datasets (points, lines, regions).
After conversion, the SMZ field will be removed from 3D point dataset attribute tables, and Z-coordinate information will be deleted from nodes. For 3D line and region datasets, Z-coordinate information will be removed from nodes.
This section uses 3D point-to-2D point conversion as an example to demonstrate feature entries and steps for 3D-to-2D data conversion.
Feature Entry
- Data tab -> Data Processing group -> Type Conversion -> 3D Point to 2D Point.
- Toolbox -> Type Conversion -> 2D-3D Conversion -> 3D Point to 2D Point.
Steps
- The 3D Point->2D Point dialog will appear. Set the source dataset, resulting dataset name and target datasource.
- Execute the conversion after completing settings.
