New Features in ENVI LiDAR 3.2

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

  • E3De has been rebranded as ENVI LiDAR.
  • The new IDL-based API for ENVI LiDAR allows you to control, extend, and automate the application. For details on programming for ENVI LiDAR in IDL, see the help topics "Write and Deploy Toolbox Extensions" and "Programming with ENVI LiDAR." You can:
  • Control the ENVI LiDAR application, such as open and close projects, add annotations, and so forth.
  • Read LiDAR data (.las, .txt, .ntf, .bin) with spatial queries and attribute filtering.
  • Write LiDAR data (.las).
  • Read and write coordinate system information.
  • Run automated feature extraction for DEM, DSM, contour lines, buildings, trees and power lines.
  • Run  in batch mode with no user interaction.Write and deploy custom extensions through the  Toolbox.Manage errors.
  • ENVI LiDAR user interface updates include the following:
  • Toolbox: You can customize your ENVI LiDAR installation by writing and adding your own tools using IDL. To view and select custom extensions from the user interface, select View > IDL Toolbox from the menu bar.
  • Operations Log: If you are running extensions from the Toolbox, the Operations Log shows output from IDL in blue text.
  • Context-Sensitive Help: Context-sensitive help is available on most dialogs. Click the question mark available at the bottom of the dialog to open help specific to that dialog.
  • The following changes were made to data processing:
  • The toolbar buttons for processing have changed. Setting parameters, previewing the results of parameter settings, and starting processing are all accessible by a single button, the Process Data button.
  • When processing is complete, the view will automatically switch to QA Mode by default. If desired, you can change the default preference to not automatically switch to QA Mode.
  • Generated products can be exported to a user-selected coordinate system. Output is no longer limited to UTM WGS84.
  • Annotations are new to this release. With annotations, you can:
  • Add text or coordinate annotations to mark places of interest, and you can easily add the current coordinate information for the annotation to that text. Annotations appear in both the Main window and (when open) the ENVI LiDAR 3D Viewer.
  • When you use the Measurement Tool to measure the difference between two selected points, the result is added as an annotation in both the Main window and (when open) the ENVI LiDAR 3D Viewer
  • Coordinate system conversion changes include:
  • When you create a project using a file that contains coordinate system information in its header, ENVI LiDAR applies that information to the project by default.
  • Additional dialogs for selecting the default coordinate system when you create a new project are available if you need advanced projection system options.
  • If you do not know the projection information for the file but wish to continue creating the project, a choice of "Arbitrary" is available in the Convert Format dialog.
  • You can capture the contents of the Main window and open the screen capture in a new or current PowerPoint™ session.

Known Issues in ENVI LiDAR 3.2

ID Description
67779 Canceling an IDL workbench launch from ENVI LiDAR causes ENVI LiDAR to become unresponsive and eventually crash.

Launching the IDL workbench from ENVI LiDAR when there is already an instance of the IDL workbench running will display the Workspace Unavailable dialog. Once the user clicks OK, the Workspace Launcher dialog will be displayed prompting the user to choose a different workspace. If the user clicks Cancel, then ENVI LiDAR will become unresponsive and eventually crash.

Workaround: Do not click Cancel in the Workspace Launcher dialog when prompted to select a different workspace. Instead, select a different workspace to continue without problem.

If you have already clicked Cancel and ENVI LiDAR has become unresponsive, then it is necessary to close and restart ENVI LiDAR.

Problems Fixed in ENVI LiDAR 3.2
