- Air traffic flow analysis from spaceborne ADS-B — Ground radar stops at the coastline. Spaceborne ADS-B receivers on Spire Global and Aireon/Iridium NEXT reconstruct full oceanic and polar trajectories, exposing route utilisation and congestion that terrestrial systems simply cannot see.
- Airport aircraft counting and stand utilisation monitoring — Very-high-resolution optical imagery at 0.3–0.5 m lets analysts count aircraft, infer type from geometry, and convert stand occupancy into throughput proxies. Published studies using WorldView and Pléiades data show the method works; the hard constraint is that no tasking system can guarantee overpass timing against a morning banking wave.
- Land border crossing queue length estimation from satellite — High-resolution optical satellites can count stationary vehicles in border-crossing approach lanes where ground sensors are absent or politically inconvenient, but the revisit problem is real and must be managed honestly.
- Cold-chain and logistics warehouse construction progress monitoring — Satellite imagery can track cold-store and logistics warehouse construction months before facilities enter official capacity databases, giving freight operators and investors a leading indicator of supply-chain infrastructure.
- Container yard occupancy measurement from SAR — Synthetic aperture radar detects and counts intermodal containers in port yards at any hour, in any weather, using the distinctive double-bounce signature of metal boxes stacked on concrete. Temporal stacking of SAR scenes converts occupancy snapshots into throughput indices.
- Dark vessel detection by fusing AIS gaps with RF and SAR — When a vessel goes dark on AIS, its radar cross-section and incidental RF emissions remain. Fusing spaceborne AIS gaps with SAR imagery and HawkEye 360 RF fingerprints produces detections that no single sensor can achieve alone.
- Inland waterway barge traffic monitoring from SAR and optical — Most inland barges are invisible to AIS networks. SAR and optical satellites can detect and count them, but low freeboard, river clutter and sun-glint geometry impose real limits that any serious monitoring programme must account for.
- Retail and industrial activity proxied by parking-lot occupancy — Counting passenger vehicles in car parks from high-resolution optical imagery is a published, peer-reviewed method for estimating retail footfall and factory shift activity before official data are released.
- Port and freight terminal activity indexed by nighttime light intensity — VIIRS Day/Night Band radiance turns port floodlighting into a continuous operational index. The method is cheap, globally consistent, and honest about its 750 m resolution floor.
- Rail wagon and intermodal yard occupancy from satellite imagery — Track geometry forces rolling stock into predictable linear positions, making satellite-based counting far more tractable than open-area vehicle detection. High-resolution optical and SAR data can count, classify and monitor loading state across classification yards and intermodal terminals globally.
- Road freight activity proxied by truck counts at logistics nodes — Sub-metre optical imagery from Planet, Maxar and Pléiades Neo can count heavy goods vehicles at distribution centres and border crossings, turning parking geometry into a daily freight-flow index.
- Vessel dwell time and berth utilisation from optical imagery — Repeated high-resolution optical passes over commercial ports let analysts measure how long individual vessels occupy berths, revealing congestion days before it surfaces in official port statistics or freight indices.
