LGRIP30 — Landsat-Derived Global Rainfed and Irrigated-Cropland Product (NASA LP DAAC)
Where crops get rain vs. a pipe — irrigated and rainfed cropland mapped at 30m across the contiguous US, a 2020 snapshot.
What this is
LGRIP30's name says 'Global,' but the current V002 release only covers the contiguous US — NASA's LP DAAC says the rest of the world is planned for a later release. It classifies cropland into three classes at 30m resolution — non-cropland, irrigated, and rainfed — from Landsat imagery, in a 2020 snapshot. UFFDA mirrors all 17 available tiles with a simple color key: blue for irrigated, amber for rainfed, everything else left transparent. Click a field and UFFDA returns its dominant class plus the irrigated/rainfed split.
Why we surface it
Irrigation is one of the biggest signals in how land is actually used — it separates weather-dependent fields from infrastructure-backed ones, and it shows up in water use, productivity, and risk. LGRIP30 maps that split at a resolution fine enough to mean something field by field.
