Lidar Toolbar

Activating Global Mapper Pro will add the Lidar Toolbar as an additional component to the Global Mapper User Interface. The toolbar provides options to change the draw or color mode, quickly classify or re-classify selected points, auto-classify Lidar points, and more.

Like other Global Mapper toolbars, this interface may be activated and deactivated in the View > Toolbars menu. See Toolbar Visibility and Customization for more information on enabling toolbars and customization.

Tools Available from the Toolbar:

Lidar Draw Mode (Color By...) (Color By...) Change the draw or color mode of displayed point cloud, which allows users to easily select the display characteristics of the data.

Lidar/Terrain Display Controls – Allows the user to dynamically filter out lidar points by classification, elevation, and other attributes. Also allows for changing the color or classification groups of lidar classes. See more information on changing the class properties. Additional advanced filtering tools can be applied while running an auto-classification or by selecting lidar points with the Digitizer tool.

Spatially Thin Lidar Layers – Thin a dense lidar point cloud using one of the available thinning methods. This is especially good for thinning dense photo-generated point clouds, such as those from Pixels to Points ®.

Apply Color to Lidar Points – Applies color values from loaded imagery to Lidar points based on X, Y location values. Color values can include R,G,B values from true color imagery, intensity values, or values from multi-band imagery or raster calculations for LAS versions 1.4.

Lidar QC - Compare/ Adjust Elevations to Control Points – Control points may be compared to nearby Lidar points. This tool reports the differences and RMSE between the control points and nearby LiDAR points. It can also be used to adjust the point cloud so the points match the control elevations.

Fit Point Clouds – Automatically align one point cloud with another.

Compare Point Clouds – Calculate the change between 2 point clouds beyond a specified minimum. This performs a change detection to find points that have different beyond a minimum allowed distance.

Create Mesh from Selected Lidar – Convert the selected lidar points into a 3D mesh surface.

Create Swath Separation Image - Generate an image showing the vertical offset between lidar swaths.

Pixels to Points ®- Using drone- or UAV-collected images and a set of surveyed ground control points (optional) generate a 3D point cloud, seamless orthoimage and/or 3D mesh output.

Selection:

Select Lidar Classes – Quick select lidar based on classification or return type. This dialog can also be used to access class name, color and group for customization.

Select Lidar by Distance – Perform a spatial query to select lidar points near other points or near lines using a 2D or 3D distance threshold.

Find Duplicate Lidar – Delete points with the same XYZ locations. You can also optionally require other attributes to match as well as XYZ.

Select Lidar Segments - With the digitizer tool, enable this option to select all points in a specific segment.

Classification:

Manual Classification - provides quick methods for manually applying classifications to selected point features.

Change Lidar Class - Options for changing the classification of the selected points.

Automatic Point Cloud Analysis - Global Mapper's broad toolset for point cloud classification, segmentation, and feature extraction.

Segmentation - A classification method for identifying features in points based on their structure.
