CALIBRATION FAILED - no volume result
Blackberry Valley Landfill (SC)
A real measurement was attempted between two independent LiDAR epochs at this site, but the stable-terrain calibration ring did not pass the pre-registered alignment thresholds - so no volume change is reported. This is a real, evidenced non-result, not a missing measurement.
| Field | Value |
|---|---|
| Verdict | INCONCLUSIVE_LOW_DATA_QUALITY |
| Confidence | n/a - no real result to score |
| Epochs | 2011 → 2019 |
| Stable-control offset | None m |
| Stable-control sigma | None m |
| Reason | puerta de calidad de dato: n_stable_control_cells=0 (<200) o usable_coverage_pct=0.0 (<50%) |
| Recommended next action | None available automatically today - the L0-L3 sensor escalation ladder (higher-resolution commercial imagery as a last resort) is not built yet. Manually: request a re-measurement with a customer-supplied real polygon via the request-access path, or try a different point if this one has no usable public LiDAR coverage. |

Method: measure_physical_change() — same unmodified function used across every site in this program, real LiDAR/3DEP epochs via the public hobuinc/usgs-lidar EPT index, calibrated against a stable-terrain control ring. Synthetic 200x200m buffer on the LMOP-declared coordinate — never the legal parcel boundary. Full method: /products/physical-change/.
