New Features

The following are new features in ENVI LiDAR 3.2 Service Pack 1. For details on each feature, refer to the ENVI LiDAR Help.

  • The new Viewshed Analysis tool enables you to determine features that can be seen from one or more observation points. You can:
    • Calculate viewshed on-the-fly as you add, move, and edit observer points
    • Interactively include and exclude selected observer points from the calculation
    • Show what is visible for any observer point or all observer points
    • Import and export observer points
    • Export the Viewshed Analysis to a raster
    • Launch the Viewshed Analysis raster in ENVI or ArcMap™
  • The DSM is now generated when you create a project and is available as a layer that can be displayed in the standard view as well as the QA Mode view. The display mode of the DSM layer can be colored by intensity, RGB, or height. 
  • Three new methods have been added to the  API:
    • E3De::CreateLidarFromSubrect: Creates a project by using a spatial subsetof LiDAR data
    • E3De::GetViewExtents: Queries the view extents of the magenta rectangle shown in the Navigate window
    • E3De::SetViewExtents: Sets view extents
  • Multi-coreprocessing has been enhanced to remove the 8-core limit. By default,all available cores will be used, or you can set the value to be a subset of the cores available on the processing machine. Multi-core processing has also been added as a property in the API.
    Updates include:
    • The CPU Cores setting was enhanced and moved from the Preferences dialog to the Production Parameters Tab of the Project Properties dialog.
    • The NUMBER_OF_CORES property was added to E3DProductionParameters.
  • The generated building perimeter shapefile (buildings_perimeter.shp) now includes attributes for Area, Perimeter, Length, Width, MinHeight, MaxHeight, and Orientation.
  • ENVI LiDAR file support has been updated to include the following:
    Input files:
    • MrSID LiDAR files
    Export files:
    • COLLADA 1.4.1 and 1.5.0
    • Google Earth KMZ

Known Issues

ID Description
LIDAR-68584 Launch Generated Products in ArcMap fails when launching a new instance of ArcMap 10.1
If you Launch Generated Products in ArcMap in ArcMap 10.1 and ArcMap is not already running, or if you choose"Start a New Instance," then the products appear in the ArcMap layer manager, but do not display in the main view.

Workaround: Launch ArcMap from the Start menu before selecting Launch Products in ArcMap. When prompted choose to open the products in the already running instance of ArcMap.
LIDAR-68356,68357, and 68358 Network project open by different machines simultaneously causes issues
When a project located on a network is open by different machines at the same time, processing errors and 3D Viewer display errors will occur.  

Workaround: Use the API method E3De::CreateLidarFromSubrect to create subprojects so multiple users can then work with subsets of the project.


Problems Fixed

ID Description
LIDAR-67881 Launching ENVI LiDAR checked out the IDL license instead of the IDL_RT license when both were present.
