Under standard acquisition conditions, Aestra Spatial datasets typically achieve centimeter-level internal consistency (often within ± 2–3 cm), providing reliable accuracy for distance, slope, and volume estimation on construction sites. All 3D models, LiDAR scans, and photogrammetry deliverables produced by Aestra Spatial / Aestra3D are provided for visualization, measurement, and analysis purposes. These datasets are suitable for construction progress tracking, volumetric estimation, slope evaluation, and general site documentation. They do not constitute a certified survey, legal boundary plan, or engineering document, and should not be used for property definition, staking, or legal measurements. Coordinates may be referenced to geographic systems (e.g. NAD83 / MTM), but absolute accuracy depends on the use of RTK or ground control points (GCPs). Any use of the data for legal or design validation must be reviewed by a licensed surveyor or engineer. Aestra3D shall not be held liable for any damages or misinterpretation arising from the use or modification of its data or visual content,
