Geospatial Insight Limited (TankWatch) — Satellite-measured above-ground crude storage inventory dataset (TankWatch): volumetric capacity and fill level of floating-roof oil tanks derived from very-high-resolution optical and cloud-penetrating radar imagery. Capacity is computed by automatic planimetric measurement of distances between tank features; fill level is derived by Shadow Positioning Analysis of the floating lid, with human quality assurance on the machine output. Delivered as near-real-time, weekly, monthly and historical series for 69 key oil storage locations worldwide, with a be…

Earsc-portal offers (Alternative, Supply Chain, Geospatial, Price) — 69 named key storage locations; at typical hub scale of tens to several hundred tanks each, order 5,000-20,000 individually measured tanks, multiplied by weekly passes over roughly a decade of operating history = order 10^6-10^7 dated fill measurements, plus the derived capacity attribute for every tank and the archive of imagery and radar passes behind them (substantially larger, and reusable as a labelled imagery corpus). Estimate from the stated 69-site coverage and weekly cadence; per-tank counts are not published..

Global oil balance construction in non-reporting regions - the core use, since this is the only way to observe stocks in China and the Middle East outside official statistics the market distrusts; price risk management and directional trading on inventory builds and draws ahead of any public disclosure; arbitrage and spread identification between reporting and non-reporting regions; verification and short-selling research testing official stock claims against measured reality; national supply-security and sanctions monitoring, detecting stockpiling or hidden accumulation; strategic-reserve sizing and benchmarking for governments; physical supply-chain and refinery run planning for operators and traders; and, distinct from trading uses, training and validating computer-vision models for industrial-asset measurement using the geometry-derived capacity, fill and QA-correction labels.

The data is with 8 years of history.
