• Clip points to a rectangle – Discard all points outside of a rectangle. Enables the following options to define the rectangle:
  • X coordinate of first point on rectangle
  • Y coordinate of first point on rectangle
  • X coordinate of second point on rectangle
  • Y coordinate of second point on rectangle
• Clip points to a circle – Discard all points outside of a circle. Enables the following options to define the circle:
  • X coordinate of center of circle
  • Y coordinate of center of circle
  • Radius of circle
• Clip points to a range of heights – Discard all points outside a range of heights. Enables the following options to define the range:
  • Minimum height
  • Maximum height
• Drop returns – Whether and how to drop returns. Options are:
  • Don't drop returns
  • Keep only first return
  • Keep only last return
  • Drop a list of returns – Enables the following option:
    • List of returns to drop, separated by space – A space-separated list of returns to drop, e.g. "1 2 3" to drop returns 1, 2, and 3. You can also specify just one number to drop only that return.
• Filter points by class – Whether and how to filter points by their classification. Options are:
  • Don't filter classes – No filtering is done.
  • Keep class – Keep only specified classifications. Enables Class to filter/drop option.
  • Drop class – Drop only specified classifications. Enables Class to filter/drop option.
• Class to filter/drop – Space separated list of classes to filter or drop.
• Set classification of points – Whether to set the classification of points in the file. If used, all points in the file will be set to the chosen classification. Enables the following option:
  • Classification to set points to – What classification to set the points to.

Output Parameters

• Output file – Where to write the output file to.
