The Point Cloud Feature Extraction tool performs feature extraction on point cloud data. Building, tree, and power line feature extraction requires an ENVI Feature Extraction license to generate. Contact your sales representative for more information.

You can also write a script to do feature extraction on point cloud data using the PointCloudFeatureExtraction task.

From the Toolbox, select LiDAR > Point Cloud Feature Extraction. The Point Cloud Feature Extraction dialog appears.

For descriptions of all available parameters and their settings, refer to the PointCloudFeatureExtraction task topic.

In addition to the parameters described in the task documentation, these additional settings are available in the tool dialog:

• Enable the Display result check box to display the output in the view when processing is complete. Otherwise, if the check box is disabled, the result can be loaded from the Data Manager.

• To reuse these task settings in future ENVI sessions, save them to a file. Click the down arrow and select Save Parameter Values, then specify the location and filename to save to. Note that some parameter types, such as rasters, vectors, and ROIs, will not be saved with the file. To apply the saved task settings, click the down arrow and select Restore Parameter Values, then select the file where you previously stored your settings.

• To run the process in the background, click the down arrow and select Run Task in the Background. If an ENVI Server has been set up on the network, the Run Task on remote ENVI Server name is also available. The ENVI Server Job Console will show the progress of the job and will provide a link to display the result when processing is complete. See ENVI Servers for more information.
