ENVI LiDAR 5.1
What's New in ENVI LiDAR 5.1
The following features were added in ENVI LiDAR 5.1. For information on previous new features, see What's New in Release 3.2 Service Pack 1, What's New in Release 3.2 and What's New in Release 3.1.
Product Version
The ENVI LiDAR version number has been incremented to 5.1 for this release, to align ENVI LiDAR version numbering with ENVI's.
Viewshed Analysis Enhancements
- New properties have been added to Viewshed Analysis for observer direction, which can be useful when the observer point has field-of-view restrictions.
- Viewshed Analysis now includes range ring settings which enable you to show range rings, and to set the intervals at which to mark them.
Programming
New sample code has been added to the Toolbox extensions.
- The Calculate Forest Density sample code shows how to process LiDAR data to classify points as vegetation, then create rasters for vegetation density and canopy height that can be opened and viewed in ENVI.
- The Reproject LAS File sample code shows how to reproject points from a LAS or LAZ file to a new LAS file.
Show Point Feature by Color
You can temporarily color point features of the area visible in the Main window. The previous two options allowed you to color the values based on point frequency and the LAS file source ID. Additional new options are:
- Surface normal: Colors points by a unit vector perpendicular to the surface.
- Classification values: Colors points by classifications computed outside of ENVI LiDAR.
- Laser return number: Colors points by the number of times a laser pulse is reflected off an object and is returned to the system receiver.
File Support
LAZ files are supported as file input.
