Randlas

A tool to generate completely random lidar files from the command line, written completely in rust.

Description

You can choose the LAS version and format, set the lateral extent and z-range, and the percent of points classified as ground. This was developed to aid in testing of various lidar formats and compression efficiency tests.

Usage

Usage: randlas [OPTIONS] <OUTPUT>

Arguments:
  <OUTPUT>  Output filename. Format is determined by extension

Options:
  -n, --num-points <NUM_POINTS>  Number of points in cloud [default: 10000]
  -m, --minor <MINOR>            LAS Minor Version [default: 4]
  -f, --format <FORMAT>          LAS Point Format (0 - 10) [default: 1]
  -g, --ground <GROUND>          Percent (0 - 100) of points classified as Ground [default: 90]
  -s, --surface                  Make Z-values surface-like
  --hills <HILLS>                Number of hills, otherwise random. Used with surface
  -x, --x <X> <X>                W-E extent (meters) [default: 0 1000]
  -y, --y <Y> <Y>                S-N extent (meters) [default: 0 1000]
  -z, --z <Z> <Z>                Z extent (meters) [default: 0 100]

Getting Started

Deps

• Tested on Arch Linux

Building

• Install from crates.io:

cargo install randlas

• Install from source:

git clone https://asub-sandwich/randlas.git

cd randlas

cargo build --release

Future Plans / Known Issues

1. Currently, only LAS and LAZ files can be generated. I would like to add ASCII and G-Zipped ASCII files, but those are currently being made by using RapidLasso's las2txt(64) binary after generation of las files.

2. More control over surface generation

3. Binary is not yet portable due to the use of the rand crate.

Additonal Disclaimers

1. This generates lidar files similar to what would be taken with Aerial Lidar Scanners, that is, evenly distributed across an area. Simulation of terrestrial lidar scanners would be interesting.

2. My programming is almost entirely self taught; if you find an issue or find that I have violated a custom, please let me know!
