如何查看 LAS、LAZ 文件
LAS and LAZ are common lidar and photogrammetry exchange formats. This tool provides a visual sanity check, not survey certification or reprojection.
- Choose a .las or .laz point cloud.
- Wait while headers and point records load in batches.
- Switch among RGB, elevation, and classification coloring.
- Check point count, bounds, scale, gaps, and obvious outliers.
Para qué sirve
- No CloudCompare installation
- Quick elevation and class inspection
- The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
Compatibilidad y limitaciones
- Large files may be sampled; displayed points can be fewer than source records
- Custom VLR/EVLR records may not be interpreted
- No reprojection, accuracy assessment, or ground classification
Preguntas frecuentes
Why does LAZ load more slowly?
LAZ must be decompressed in the browser, so time depends on file size and device performance.
Can I measure true distance?
Measurements only make sense when units and CRS are known; verify deliverables in survey software.
Is the point cloud uploaded?
The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
