Merging LiDAR Point Clouds in Lixel Studio

This tutorial outlines how to merge separate LAS point cloud datasets quickly and cleanly within the desktop compilation environment of XGRIDS Lixel Studio. Combining heterogeneous spatial sensor data provides a more complete, gap-free reconstruction of complex job sites by unifying different tracking perspectives into a standardized output.

To demonstrate a comprehensive cross-platform compilation workflow, this guide features datasets originating from two separate hardware methods: a handheld terrestrial mobile mapping run via the XGRIDS Lixel L2 Pro, and an airborne mapping pass via the DJI Zenmuse L2 UAV payload. Prior to initiating the merging sequence, each raw target dataset was compiled, filtered, and tightly clipped to focus boundaries to ensure a highly precise, artifact-free final point cloud deliverable.

Dataset Selection & Tools

Execute the following step-by-step software commands to compile your distinct point files together into a combined matrix:

• Launch Lixel Studio on your workstation and pull the pre-clipped LAS point cloud files into your current active layout workspace environment.
• Open the primary database dashboard interface, navigate directly to the **Data Management** panel window view, and highlight both imported file strings simultaneously.
• With your chosen target layers cleanly highlighted, invoke the merging algorithm through either of two extraction paths: right-click across the active text selections to choose Merge from the pop-up context menu, or navigate up to the horizontal utility panel and click the explicit Merge icon found inside the primary Tools banner layout.

Merge Parameter Settings

An export configuration dialog card will appear across your screen viewport. Apply your targeted configuration properties within the respective parameter card fields:

• Verify and select the specific imported datasets you want to pass to the merging script.
• Choose the specific LAS format version profile revision string you require for your downstream data extraction or third-party engineering programs.
• Designate a unique output file string name and specify the targeted directory destination path where your combined spatial model asset should be saved.

Click OK to commit your parameters and execute the background compilation loop. After approximately one minute of automated calculation runtime, the desktop processing engine concludes, populating a flawlessly unified, georeferenced merged point cloud layer directly within your project workspace tree.
