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.
