Southern California 30 m Irrigated Vegetation Map

This dataset represents a high-resolution irrigated land use map across the Southern California Air Basin (SoCAB) with a spatial resolution of 30 m. This map was developed to support urban biospheric CO2 and hydrological modeling in Los Angeles, CA. The map distinguishes between irrigated and non-irrigated vegetation and masks out all non-vegetated surfaces in SoCAB. The land use map was derived from a combination of vegetation-fraction weighted ECOSTRESS land surface temperature (LST) imagery and Landsat-8 optical imagery.

Band 1: Irrigated vegetation classification (0 = non-vegetation, 1 = irrigated vegetation, 2 = non-irrigated vegetation)
Band 2: Irrigated vegetation classification uncertainty (e.g., 0.65 = 65% confident that the supervised classification model correctly predicted a pixel was irrigated or non-irrigated)
