CloudAnalyzer/ WEB Open app

A workspace for spatial data

A new
perspective on
point clouds.

Explore a scan. Bring a map together. See what changed. Go from raw points to a clearer picture, right in your browser.

01 / GET HANDS-ON

Less setup.
More discovery.

Start with a sample. Orbit, inspect, and run the analysis yourself.

The same NCLT campus block scanned in two seasons, with differences colored on the map.REAL DATA · NCLT
01 / SLAM & CHANGE

Same place. Different season.

Join two recorded drives and inspect the changes between April and June.

Explore two seasons · 19 MB sample

02 / DISTANCE

Make the difference visible.

Compare two LiDAR scans. Turn point-to-point distances into a readable heatmap.

A stockpile point cloud with cut and fill volume analysis in the browser.CUT / FILL
03 / VOLUME

Put a number to the shape.

Measure a stockpile or compare surfaces. Inspect cut and fill from every angle.

02 / FROM SCAN TO UNDERSTANDING

Your whole workflow.
One open workspace.

Follow the geometry, from the first look to the final measurement.

Read the field guide
01

Bring it into view.

Open local scans, stream a COPC file, or replay a recorded drive. Color by height, intensity, or classification.

02

Find the structure.

Align with ICP, close SLAM loops, extract the ground, and inspect cross-sections. Draft and edit Lanelet2 maps over your cloud.

03

Measure what matters.

Compute distances, detect change with M3C2, and calculate cut and fill. Export results to take your work further.

03 / UNDER THE SURFACE

Built for the details.

Open source. Local processing.
Room to explore.

Your data stays local.

Open your files directly in the browser. Analysis runs on your machine, with no account or upload step.

Go beyond the preview.

Inspect dense clouds with point budgets, full-detail loading, and COPC streaming. Explore with mouse or touch.

Keep your work moving.

Save a session, share a view of URL-loaded data, and export clouds, measurements, trajectories, and maps.

Explore the full toolkit
  • PLY, PCD, LAS/LAZ, E57, XYZ and URL-based COPC streaming
