TOPS Satellite Irrigation Management Support (SIMS)

NASA and USGS satellites were used to map crop development and crop water demand throughout California's Central Valley, Central Coast, and North Coast at a spatial resolution of 0.25 acres from 2010 to present. Through this prototype interface, users may view maps and inspect/download time-series trends of selected data layers at user-specified locations. The datasets are intended to provide additional information about crop canopy conditions and irrigation demand for agricultural producers and water managers. This interface is being made available for review and evaluation by California growers and other interested stakeholders.
