9.1 Point Clouds File​

Click Point Clouds menu, click [New Clouds] button, then enter the name in Create Point Clouds box and click [Create].

Figure 9.1 New Clouds

After creating clouds, the new clouds will be displayed in Work Space window.

Click Point Clouds menu, click [Edit Clouds] button, to open clouds editing interface for subsequent LAS file import and point clouds datasets editing operations.

After importing, the imported files will be displayed in the Las source file list. And the item could be deleted if the delete icon is clicked.

9.3 Datasets​

Click Datasets [+] button, check the LAS files that need to be imported into datasets, and check the column attributes in LAS files to import. Input the name, click [OK] and wait for the import to complete.

After datasets importing, the imported datasets will be displayed in the datasets list. And the item could be deleted if the delete icon is clicked. The interface displays the point clouds graphic for the checked datasets. Use the mouse wheel to zoom the display. Use the left mouse button to rotate the display and the right mouse button to drag the display, to adjust the 3D display angle of point clouds.

In datasets list, select item and lick [Rename] to change the name of selected item.

Select item and click [Copy] to copy the selected item, avoiding subsequent edits affecting the original dataset.

Select two or more datasets, click [Merge] and enter the name of merged datasets to merge LAS data contained in the two datasets into one dataset.
