Why Developers Choose GLBKit for LAZ
GLBKit decompresses laszip-compressed LAZ files in the browser and streams the point cloud to the GPU. It is useful for inspecting compressed LiDAR datasets without downloading desktop GIS software.
Browser Based LAZ
Open compressed LAZ files directly in your browser without installing software.
Local File Processing
Decompress and process compatible LAZ files locally on your device.
Fast Decompression
Stream laszip-compressed LiDAR to the GPU without a server.
Large-Scale LiDAR
Inspect compressed LiDAR datasets without downloading desktop GIS software.
Lossless LAZ Fields
Preserve intensity, classification, RGB, and GPS time from the source LAS.
No Server Upload
Inspect LAZ files without uploading them to a remote server.
About this format
LAZ is the lossless compressed variant of LAS, defined by Martin Isenburg in the laszip library. It typically reduces file size by 4-10x with no data loss, making it the preferred format for distributing large LiDAR datasets. GLBKit renders .laz files in the browser so you can inspect compressed LiDAR surveys without unpacking or uploading them.
What is a .laz file?
.laz is a lossless compressed LAS file. It uses the laszip library to compress the point records while preserving all of the LAS metadata, classification, and RGB fields.
LAZ is the standard distribution format for open LiDAR datasets, government surveys, and large forestry or corridor mapping projects.
- Lossless compressed LAS format
- Typically 4-10x smaller than uncompressed LAS
- Preserves all metadata, classification, and RGB
- Standard for open LiDAR datasets and large surveys
Common uses for LAZ files
LAZ is the format you download when you get a public LiDAR dataset. It is the standard for open data portals and large-scale survey distribution.
- Open LiDAR datasets (USGS, national mapping agencies, OpenTopography)
- Large airborne and terrestrial surveys
- Forestry, corridor, and infrastructure mapping
- Distribution format for compressed survey data
How GLBKit renders .laz files
GLBKit decompresses the .laz file in the browser and renders the point cloud with WebGL. The decompression is fast, and no data is uploaded.
- Drop a .laz file to start
- Orbit, pan, and zoom with mouse, touch, or pen
- RGB color and intensity preserved
- No upload, no signup, fully local processing
GLBKit capabilities for .laz
GLBKit renders LAZ point clouds with the same fidelity as LAS. You can inspect geometry, color, and intensity, but you cannot run classification or filtering in the viewer.
- Point cloud rendering with RGB and intensity
- Efficient LAZ decompression in the browser
- Inspect compressed LiDAR surveys
- Process files locally in the browser
Who uses GLBKit for .laz files
If you download LiDAR from an open data portal, you are downloading LAZ. GLBKit is the fastest way to inspect it.
- Surveyors and geomatics engineers
- Foresters and ecologists
- GIS analysts working with open LiDAR data
- Researchers using public LiDAR datasets
