Las To Text

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

Input Parameters

• Lidar file to process – A LIDAR file to convert to text.
• Parse string – Indicates how to parse the file. See #Parse Strings below for more details. Optional. Defaults to xyz.
• Header comment character – If specified, the contents of the LIDAR file's header will be written to the top of the output file, with lines commented out by the chosen comment character. Specify No header to not produce any header.
• Field separator – The character used to separate fields in the text file.

Output Parameters

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

Parse Strings

Las To Text needs to know what order to write fields into the output file. 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. No other fields are produced.

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.
