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,…
