2D data and 3D Data Conversion

2D Data to 3D Data

With Type Conversion, you can convert a 2D Dataset (point, line, surface) to a 3D Dataset (point, line, surface).

When a 2D Dataset is converted into a 3D Dataset, the fields and Attributes of the original 2D Dataset will be retained, and a Z field (elevation information) will be added to the data object, that is, the corresponding Nodes. See the Querying and Modifying Properties of an Object for how to view the Nodes for Select Objects.

When a Point Dataset is converted to a 3D Point Dataset, a Z field is added under the Nodes of the data object, and an Elevation Field (SMZ) is added to the Dataset Properties table.

Load the converted 3D Data into the scene for display. On the Layer Properties tab, set Height Mode to non-ground mode, and the 3D Data object displays the height of the point as a value at the Z coordinate.

Here, we take the conversion of 2D line data into 3D line data as an example to introduce the function entrance and operation instructions of converting 2D data into 3D data.

Function entrance

  • Data tab-> Data Processing group-> Type Conversion-> 2D Line to 3D Line.
  • Toolbox-> Type Conversion-> 2D Data and 3D Data Conversion-> 2D Line to 3D Line.

Operating instructions

  1. Click 2D Line to 3D Line, and set the Dataset to be converted, the Resulting dataset name, and the stored Datasource in the pop-up dialog box
  2. Select the field as the elevation value, or click the box corresponding to the Z coordinate bar with the left button to activate the input state and then set the elevation value manually. Line data contains two elevation values, the start and the end. For point data and surface data, only one elevation value can be set.
  3. Once the setup is complete, the conversion operation can be performed.

3D Data to 2D Data

Type Conversion lets you convert a 3D Dataset (point, line, surface) to a 2D Dataset (point, line, surface).

When the conversion is complete, the SMZ field is removed from the attribute table in 3D Point Dataset, and the Z coordinate information is removed in Nodes. The 3D Line Dataset and 3D Region Dataset strip the Z coordinate information from the Nodes.

Here, we take the conversion of 3D point data into 2D point data as an example to introduce the function entrance and operation instructions of converting 3D data into 2D data.

Function entrance

  • Data tab-> Data Processing group-> Type Conversion-> 3D Point to 2D Point.
  • Toolbox-> Type Conversion-> 2D Data and 3D Data Conversion-> 3D Point to 2D Point.

Operating Instructions

  1. In the 3D Point-> 2D Point dialog, set the Dataset to be converted, the Resulting dataset name and the saved Datasource.
  2. Once the setup is complete, the conversion operation can be performed.
