Point Cloud Tasks

Point Cloud Tasks

What is a Point Cloud Task (PCT)? A function (Extract ground, Conflate Line) that operates on points 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.

  • Select the Point Cloud Tasks tab
  • Under the Point Cloud Tasks drop-down menu select Add Task
  • Specify the Task Type you are trying to add and provide the task with a unique name
  • After clicking OK the task is now added to the Point Cloud Task List

Removing a task

Remove the task from the current task list

  • Select the Point Cloud Tasks tab
  • Select a PCT from the task list
  • Under the Point Cloud Tasks drop-down menu select Remove Selected Task…

Rename a task

Rename the selected task

  • Select the Point Cloud Tasks tab

  • Under the Point Cloud Tasks drop-down menu select Rename Selected Task…

Copy a task

Make a clone of the selected task

  • Select the Point Cloud Tasks tab
  • Select a PCT from the task list
  • Under the Point Cloud Tasks drop-down menu select Copy Selected Task…
  • Provide the copied task with a unique name

Import a task

Import a task in XML format

  • Select the Point Cloud Tasks tab
  • Under the Point Cloud Tasks drop-down menu select Import Task(s)…
  • Browse to the location of the task XML file

Export a specific task

Export only the task current selected in the task list in XML format
