Verified - counted or confirmed by you.
The number of record. Overrides everything else and survives all data refreshes.
Double-Checked - map and satellite agree.
Satellite AI (free Sentinel-2 imagery, 10m) independently confirmed the mapped tanks it can resolve (≥25m diameter). Two sources, no human yet.
Mapped - unverified - tanks individually mapped in OpenStreetMap.
Good indication of what is on the ground, but community data can lag reality or miss tanks - the drawn circles are the mapped tanks only, the real site may have more. Verify before quoting it.
No count yet - site known by name only.
We know a facility is there (registries, manual entry) but nobody has counted its tanks. Where the satellite has scanned, an ≈ estimate is shown. Open Google Earth, count, save.
Satellite counts see tanks ≥25m diameter only (free 10m imagery) and are AI estimates, not ground truth. Your verified number always wins over any analysis.
