This project aims to overcome the scientific and technological challenges preventing soil water and vegetation forecasting at useful land management scales (eg. 25 m). The significance is in enabling an unprecedented hyperresolution modelling capability for Australia through the integration of new ecohydrological theory with a range of satellite observations. Outcomes include more accurate, spatially-detailed information of current soil water amounts, and reliable forecasts of vegetation condition several months into the future. This will greatly enhance timely decision making and forward planning by farmers, fire agencies, and other land and water managers, with corresponding increases in productivity, sustainability and community safety.

该项目旨在克服科学和技术挑战，防止在有用的土地管理规模（如土壤水分和植被预测）。25米）。其意义在于，通过将新的生态水文学理论与一系列卫星观测相结合，使澳大利亚具备了前所未有的超分辨率建模能力。其成果包括更准确的，空间上详细的信息，目前的土壤水分，并可靠的预测植被状况几个月后的未来。这将大大提高农民、消防机构和其他土地和水资源管理人员的及时决策和前瞻性规划，并相应提高生产力、可持续性和社区安全。
