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.
