A Go library for parsing, reading, and converting ASPRS LAS 1.4 LiDAR point cloud files.

• Full support for LAS 1.1–1.4 public header, VLRs, EVLRs, and all point formats (0–10)
• CSV export of point data
• Extensible for custom VLRs/EVLRs
• Written in pure Go, no C dependencies

go get github.com/dalir/las

package main

import (
	"github.com/dalir/las"
	"log"
)

func main() {
	lasFile := las.Las{}
	if err := lasFile.Parse("./pointcloud.las"); err != nil {
		log.Fatalf("error parsing LAS file: %v", err)
	}

	if err := lasFile.Las2txt("./pointcloud.txt"); err != nil {
		log.Fatalf("error converting to txt: %v", err)
	}
}
