Quickstart

Scientific validation

Local-first by design

Files are read and rendered in your browser. There is no server to upload to, so your data never leaves your device.

Twelve import formats, four streaming

LAS, LAZ, E57, PLY, OBJ, GLB/GLTF, XYZ, CSV, PCD, PTX, PTS for static loads, plus four streaming paths with bounded memory: progressive COPC and EPT, 3D Tiles PNTS tilesets, and out-of-core LAS / chunked LAZ indexed via OPFS.

Honesty about uncertainty

Every scientific product carries an explicit evidence level, and the claim register records what each result may and may not be called.

Claim register

Terrain intelligence

A confidence-aware DTM and contour pipeline with hold-out validation, evidence-graded exports, and a quality gate that refuses to overstate.
