Site Summary
-------------------------
Borings (10): SB-01, SB-02, SB-03, SB-04, SB-05, SB-06, SB-07, SB-08, SB-09, SB-10
Highest reading in the boring logs: 653.8 %RE (SB-02).
Site background: about 3.0 %RE, the median of every reading. Display threshold on the results page: 7 %RE, twice that (the viewer files opened on their own start at the job's threshold).
Interpolated %RE range: 0.0 - 534.7 %RE
  The interpolation's inputs are the highest reading in each 30 cm (1.0 ft) depth interval of each boring, and its grid cells rarely sit exactly on a boring, so its peak usually differs from the highest single reading: most often lower, sometimes slightly higher where kriging overshoots between high readings.
Grid: 3 m cells across, 0.15 m deep, from 0.00 m below ground surface down to how deep the borings were logged around each spot: each boring's deepest reading, interpolated between borings. Nothing deeper is estimated.
Variogram: spherical, fitted to this job's data (the horizontal range on log %RE, so a few very high readings can't swing it): correlation range 39.8 m horizontally and 3.24 m vertically; nugget 441 and sill 9,161 (%RE squared).
Interpolated area: estimates are shown only where the boring data support them: where the kriging variance is below 90% of the no-data level. This job's no-data level is 9,557 %RE squared, so the cut-off is 8,602. Beyond it the 3D view, plan view and volumes are left blank. Inside it, estimates can still reach well past the outermost borings; how far depends mostly on the horizontal range above.
Extrapolated area: the part of the interpolated area outside the borings' footprint, the outline joining the outermost borings. Inside the footprint every estimate has borings on more than one side; in the extrapolated area it reaches past the outermost borings, so treat it as less certain. The 2D view hatches this area and draws its contour lines dashed.

Audit status: WARN
  - WARN: Largest depth gap is 48.8 cm (1.6 ft), from 304.8 to 353.6 cm (10.0-11.6 ft), over the 15.0 cm (0.5 ft) threshold. Left as a gap; no readings are filled in. [SB-03]
  - WARN: 1 depth value(s) appear more than once: 182.9 cm (6.00 ft). At each, the reading with the highest %RE is kept. [SB-02]
  - WARN: 11 of 562 records missing at least one channel value. Left blank, not set to zero. [SB-02]

Units, Coordinates and Depths
-------------------------
Coordinates: EPSG:6396 (NAD83(2011) / Alaska zone 3), in meters.
Depths are measured below each boring's own ground surface. Ground
surface elevations (optional in the coordinates file) are not used:
every boring starts at the same level in the 3D view, plan view and
volumes.
Boring logs: depth in feet (meters on the right axis). This file and
the audit report: depths in centimeters (feet in brackets). 3D view,
plan view and grid: meters. Volumes: cubic meters (cubic yards on
the static chart's right axis, or the interactive chart's switch).
Cleaned dataset: depths in feet and meters.
The 3D view's vertical scale is exaggerated 3x.

Cleaned Dataset
-------------------------
cleaned_logs.csv holds the 4,699 readings in 10 boring(s) that every figure and volume here is built from, after cleaning: depth in feet and meters, %RE and each channel as reported, and each boring's coordinates.
Cleaning dropped 1 reading(s) that shared a depth with another, keeping the higher %RE: SB-02 (1).
Each change is listed in cleaning_changes.csv. Not changed, by design: depth gaps stay gaps and missing channel values stay blank; nothing is filled in or averaged. The audit report lists them.

coordinate system, and its contour lines as GeoJSON in WGS84
longitude/latitude.

Every figure between and beyond the borings shows estimates, not
measurements. See https://lif-viz.io/disclaimer.
