StrataDelta

StrataDelta is an offline-first field application for repeat near-field 3D capture and geometric change review on supported LiDAR-equipped iPhones. Create a controlled project record, capture baseline and repeat observations, inspect provenance-backed quality signals, align observations, and review signed geometric change. StrataDelta keeps raw observations separate from derived products and records reviewer decisions in an append-only audit trail. Key capabilities: • LiDAR and ARKit scene-depth capture from an authorized position • Immutable raw observations and reproducible processing recipes • Reviewable tracking, coverage, confidence, motion, thermal, and storage evidence • Baseline-to-repeat registration with residual and overlap statistics • Signed change maps, cross-sections, bounded areas, and volume summaries • Named quality, registration, and finding decisions • Offline JSON, PDF, CSV, PLY, and PNG evidence exports Important: StrataDelta is a professional review aid. It is not a slope-failure warning system, a certified survey instrument, or authorization to enter a hazardous area. Automatic results are suggestions until reviewed under your organization’s approved procedure. Device accuracy and field uncertainty must be independently validated for the intended use. All project processing occurs on the device. StrataDelta contains no advertising, analytics SDK, account system, or automatic cloud upload.
