Inspect uncompressed LAS clouds in 3D: color by elevation, intensity, classification or RGB, filter by class, clip, measure, profile and estimate volume. Free, no upload.
Processing and data safety
Section titled “Processing and data safety”This tool runs entirely in your browser — your files are never uploaded to a server.
Input and output
Section titled “Input and output”- Formats: LAS
- Flow: LAS → in-browser 3D view
How to use
Section titled “How to use”- Open a .las file — it parses with progress and can be cancelled anytime (files over ~4 million points are downsampled for display); or click Load sample for a built-in synthetic terrain.
- Pick a color mode and preset (classic/spectral/mono) and point size; optionally switch on EDL depth enhancement.
- Toggle classes in the legend, narrow the intensity range, or set a clip box (X/Y/Z min·max) to focus the display.
Key details and limits
Section titled “Key details and limits”- Uncompressed LAS 1.0–1.4 point records only (RGB is read for point formats 2/3/5/7/8/10); LAZ must be decompressed first.
- Files with more than ~4 million points are downsampled for display.
- The clip box filters the display only — no data modification or export.
