LiDAR

LiDAR (Light Detection and Ranging) is a remote sensing method used to examine the surface of the Earth. In this application, users can upload LiDAR datasets directly into the Data Layers panel for visualization and interaction. The platform currently supports .laz file formats, which are compressed versions of standard LAS files commonly used in geospatial data analysis. This functionality allows users to visualize dense point clouds, perform spatial analysis, and overlay data on 3D base maps within the SiEGA platform.

How To Use Lidar

The LiDAR section is located within the Data Layers panel, beneath the GeoJSON option. To begin importing a LiDAR dataset, click the import button (downward arrow icon) next to the LiDAR category.

Once the import button is clicked, an Import Window labeled "LiDAR Import" will appear in the center of the screen. To proceed, click the "Select a file" button to browse your local files for an appropriate .laz dataset.

Navigate through your local directories and select a .laz file to upload. In this example, the user selects G_Sw_Anny.laz. Only .laz files are currently supported by the system.

After selecting a file, the system will automatically begin uploading the data. A loading screen will display the upload progress as a percentage, indicating how much of the file has been processed.

Once the upload is complete, the LiDAR Import window will prompt you to input:

• A name for the asset

• Geographic coordinates (longitude, latitude, and elevation) You may also click "Zoom" to center the camera view on the asset’s location. Once all fields are finalized, click Submit to proceed.

After submitting, the imported LiDAR dataset will appear as a listed item under the LiDAR section in the Data Layers panel. From here, you can:

• Click the magnifying glass to zoom directly to the asset’s location.

• Click the trash icon to remove the asset from the session.

How to Move a LiDAR Object

To begin moving a LiDAR object, click the Select Mode button located on the right-hand toolbar (highlighted in yellow with a square cursor icon). This mode allows you to select and manipulate assets in the scene.

Once Select Mode is active, use your mouse to drag a selection box around the asset or actor(s) you wish to move. The dashed rectangle indicates the selected area within the scene.

When a valid actor is selected, a transformation gizmo will appear at the center of the object. This gizmo allows for:

• Translation (movement) using the directional arrows

• Rotation by selecting the curved handles

• Scaling through the bounding box handles

Additionally, a control panel appears at the top of the screen, giving you further options to delete, translate, rotate, or scale the selected object.
