Using "3D Lidar Viewer"
This viewer is used to display lidar point data.
Usage:
- Open one or more lidar files using the "File" pulldown menu.
- Manipulate the lidar data in three dimensions using the mouse:
- Drag while holding down the left mouse button to rotate the data.
- Drag while holding down the right mouse button to translate the data.
- Use the mouse scroll wheel to zoom the data in and out.
- The data can be viewed as points, a wire mesh, or a surface.
- The data colors can be set to correspond to elevation, intensity, vegetation height (if the data has been filtered), return number, scan angle, classification, or an image.
- The colors of the data, background, and optional axes are all customizable.
- The viewer also includes the capability to save a screen capture.

Notes:
- This viewer requires data that are in the LAS format.
- This viewer is based on FSC_SURFACE by David Fanning.
- Because most data sets contain far too many points for the viewer to adequately display, a random subset of points are utilized. The number of subset points can be adjusted by the user under "Properties".
- If the colors are set corresponding to an image ("Style->Surface Color Type->From Image"), the source image must be in the same projection as the lidar data and must completely cover the the geographical extent of the lidar data.
