Multi-algorithm satellite survey
A continent-scale map of center-pivot irrigation, built from Sentinel-2 — checked by every algorithm we can throw at it.
For each state we run several independent pivot detectors against a cloud-free 10 m Sentinel-2 composite, then cross-check against published reference inventories. Every algorithm is shown as a toggleable map layer — your eyes are the final judge.

Methodology details on the methods page. Each region page shows per-algorithm counts and a layer-toggle map so you can see how the methods disagree.
