Exercise 3. Measurements

All LiDAR360’s measurement tools are available from the following toolbar.

Add Data

3.1 Point Selection

Use Pick Point tool to select a point. Examine the 3D- Coordinate, Intensity, Return Number, Classification, and Time attributes of the point in the resulting window.

3.4 Area Measurement

Click on the Area Measurement tool to find the display switches to a top view, allowing you to define a measurement area in the 2D display by left clicking. The area measurement result will keep updating as you add vertices to the measurement polygon. Double click to complete the area measurement polygon.

3.5 Angle Measurement

Use the Angle Measurement tool to measure angles between data points.

When in 2D view, left click on intended data points to define an angle to be measured, double click to complete. This measures the defined angle in a horizontal plane.

3.6 Height Measurement

Height Measurement tool is only enabled in 3D view. Click on a data point to start, move around to other points to see the height measurement change, and then double click on an end point to complete the measurement.

LiDAR360 Software Basics

Try rotating or moving the point cloud loaded into the Viewer of [Focus] if the measurement text box is blocking a point to be included in the taking of a height measurement.

3.7 Volume Measurement

Click on Volume Measurement tool , then click on intended data points to define a measurement boundary. Double clicking to complete the area and this will bring up the Volume Measurement window. Set measurement parameters as needed and then click Compute to see the results.

LiDAR360 Software Basics

Working in a top view with View Mode set to Orthogonal Projection may make it easier to define a boundary.

The reference plane of volume calculation is defined together by your specified boundary and height. The resulting Cut and Fill volumes are relative to the reference plane.

3.8 Density Measurement

Click on the Density Measurement tool , the display will switch to a 2D View and the Density Measurement window will appear. Set the Width value to 25, and then click on the center of the intended area to make a measurement in a 25 x 25 square window.
