laz2las

A Python script to convert LAZ files to LAS format, with error handling and improved functionality.

Usage

python laz2las.py [options] <LAZ_files>

# Example: Convert all LAZ files in the current directory
python laz2las.py *.laz

# Example: Convert specific LAZ files and specify output directory
python laz2las.py --output_dir /path/to/output data_1.laz data_2.laz

Options:

• -o, --output_dir: Specify the directory to write the LAS files. Defaults to the current directory.

Dependencies

• laspy

Installation

Ensure you have Python and the laspy library installed:

pip install laspy

How it Works

The script iterates through provided LAZ files or all LAZ files in the current directory (if no files are specified). It reads the LAZ data using the laspy library and writes the data to a new LAS file with the same name but a .las extension. The script also includes the following improvements:

• Error handling: Handles potential errors like missing LAZ files or issues during conversion.
• File existence check: Checks if the output LAS file already exists to avoid overwriting data unintentionally.
• Informative messages: Provides clear messages about successful conversions and encountered errors.

Example

If you have the following LAZ files in your current directory:

• data_1.laz
• data_2.laz

Running the script with python laz2las.py *.laz will create the following LAS files in the current directory:

• data_1.las
• data_2.las

Note: This script is designed for basic conversion and can be further customized for specific needs.

Unit Tests

The script includes unit tests to ensure its functionality and reliability.
