Create 3D Dataset

Feature Description

SuperMap iDesktopX typically stores spatial data directly in corresponding types of datasets. For example, to create spatial data of the 3D point type, you need to establish a 3D point dataset in the target data source. If different 3D point data have different purposes and meanings, you can create multiple 3D point datasets within the data source, with each dataset storing 3D point spatial data of the same usage. Similarly, you can create 3D line datasets for storing spatial data of the 3D line type, 3D region datasets for storing spatial data of the 3D region type, and so on.

There are two main methods to create a 3D dataset: creating a new 3D point, line, or region dataset; or converting an existing 2D dataset into a 3D dataset containing Z-values. For the conversion method, refer to the Type Conversion Overview page. Z-values are primarily used in GIS features to include elevation (absolute height or height relative to the ground) and other vertical measurements (such as air pollution observations or temperature).

Operational Steps

Below, taking the creation of a new 3D region dataset as an example, we describe how to create a 3D region dataset named Region3DDataset in the file-based data source china400.udb (path: SuperMap iDesktopXInstallation Directory\SampleData\China).

  1. Start the SuperMap iDesktopX application and open china400.udb (path: SuperMap iDesktopXInstallation Directory\SampleData\China).
  2. Open the "New Dataset" dialog box using one of the following methods:
    • In the Start tab of the ribbon, within the New Dataset group, click the 3D Region button.
    • Right-click the collection node of the target data source under the "Workspace Manager," select the "New Dataset" option from the context menu, and then choose "3D Region" from the submenu.
  3. The "New Dataset" dialog box will appear. Set the necessary parameters for creating the 3D region dataset in this dialog. Each record in the dialog corresponds to a dataset to be created (this dialog allows batch creation of datasets). For parameter descriptions of the "New Dataset" group tab, refer to the "New Dataset" Group page.
  4. The "Target Data Source" field in the dialog is used to set the target data source where the new dataset will be located. Click the cell of this field to turn it into a combo box. Click the drop-down button on the right to display a list of all currently open data sources in the workspace. Select a data source as the target for saving the new dataset; here, choose the "china400" data source.
  5. The "Dataset Name" field in the dialog is used to set the name of the new dataset. Enter the name for the new dataset as: Region3DDataset.
  6. After completing the settings, click the "Finish" button. Once the dataset is successfully created, the dialog will close automatically.
  7. A new node with the display name "Region3DDataset" will appear under the "china400" data source node in the Workspace Manager, corresponding to the newly created 3D region dataset.
