Polygon Filtering

In this section:

Introduction

This command is executed from folders of type Generic and will operate on data with schema type Multibeam Survey, Pointcloud, Poly Data or Structured Points (surfaces).

The command is removing data either inside or outside polygons.
For Multibeam Survey and Pointcloud data the removed data will be flagged as Polygon Filtered. The filtering can be reverted by the Revert Flagged Points command. 
For Poly Data and Structured Points the original data item is kept, and the filtered dataset gets the postfix _Clipped.
