Text To Las

The Text To Las tool converts LIDAR data from a standard ASCII format into the more efficient binary LAS and LAZ formats.

Input Parameters

  • Text file to process – An ASCII file containing LIDAR data.
  • Parse string – Indicates how to parse the file. See #Parse Strings below for more details.

Output Parameters

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

Parse Strings

Text To Las is intelligent enough to handle common field separators inside a text file, but it needs to know what the resulting numbers mean. Parse strings provide that information.

An example parse string: xyzt

This indicates that the first field on each line is the X coordinate of a point, the second field is the Y coordinate, the third is the Z coordinate, and the fourth is the GPS time. Any other fields are discarded.

Other supported characters are:

  • a – Scan angle.
  • B – Blue channel of RGB color.
  • c – Classification.
  • d – Direction of scan flag.
  • e – Edge of flight line flag.
  • g – Synthetic flag.
  • G – Green channel of RGB color.
  • h – Withheld flag.
  • i – Intensity.
  • I – NIR channel.
  • k – Keypoint flag.
  • l – Scanner channel.
  • n – Number of returns of given pulse.
  • o – Overlap flag.
  • p – Point source ID.
  • r – Return number.
  • R – Red channel of RGB color.
  • s – Number should be skipped.
  • t – GPS time.
  • u – User data.
  • x – X coordinate of the point.
  • y – Y coordinate of the point.
  • z – Z coordinate of the point.
  • 0 – First additional attribute specified.
  • 1 – Second additional attribute specified.
  • 2 – Third additional attribute specified.
  • 8 – Nineth additional attribute specified.
  • 9 – Tenth additional attribute specified.
