Point Cloud Tasks

What is a Point Cloud Task (PCT)? A function (Extract ground, Conflate Line) that operates on points, rasters, and/or vectors. A task can be a filter and/or an extractor. A filter classifies or changes the classification values for points (e.g. classify ground). An extractor extracts information from the point cloud data into vector, image or informational files (e.g. Point Cloud Statistics). The Point Cloud Tasks are accessible on the Point Cloud Task tab of the Table of Contents in Arc (when using the LP360 for ArcGIS extension) or in LP360. LP360 v2018.2 introduced the Point Cloud Task Manager.

See An Introduction to the Point Cloud Task tutorial for more information.

PCT I/O Manager (IOM)

This IOM allows setting of layers and files for both input and output. For our example, we are setting
data for a single output file and therefore, we click in the File/Folder field of the IOM row. For complex
tasks and/or macros, the IOM can have many rows. The row that contains the data for the selection you
are currently working will be highlighted in green. See the Point Cloud Tasks – The I/O Manager for more information.

LPRunPCT – PCT Command Line Tool

Do you ever find yourself performing the same point cloud task over and over again for larger datasets? A tool may help by allowing you to run point cloud tasks from the command line. Named “LPRunPCT.exe”, this application contains a number of command line options and associated parameters for running point cloud tasks via the Windows Command Line Interface (CLI). This has proven useful for customers who perform large numbers of routine tasks, such as classifying ground, vegetation, or buildings over large areas. All you need to do is create a point cloud task, set its parameters, and then save that task as an .xml file. Then you are ready to execute that task using LPRunPCT.exe.

It is important to note that in order to run a point cloud task from the command prompt, a separate license instance is required.
