Satellite remote sensing products in operation are changing the management and science of pastures . Calculation 、 Advances in data storage and processing have removed obstacles that previously prevented or hindered the development and use of remote sensing products . When combined with local data and knowledge , Remote sensing products can provide information for decision-making on various scales .
We use the time convolution network to make a partial coverage product across the ranch in the western United States . We use it 52,012 A field vegetation plot to train the model , To predict annual herbs and grasses at the same time 、 Perennial herbs and grasses 、 shrub 、 tree 、 Fraction coverage of garbage and bare land . To help explain and provide measures of predictive confidence , We also made space-time specific 、 Pixel level uncertainty estimation . We use the 5780 The model was evaluated on field vegetation plots .
The average absolute error of model evaluation is 6.3%, The average square root error is 9.6%. Evaluate with other data sets that are not part of the training data set , These data sets are geographically 、 Collection methods 、 There are differences in scope and size , Show similar indicators . Compared with the previously generated score products , Model performance has improved in all functional groups .
The progress made in the new pasture partial mulch products has expanded the management toolbox , The prediction of partial coverage and pixel level uncertainty are improved . New products can be found on the farm analysis platform （https://rangelands.app/） Upper use , The platform is an interactive network application , Track pasture vegetation through time . When explaining , The product is designed to work with local field data 、 Expert knowledge 、 Land use history 、 Scientific literature is used in conjunction with other sources of information . When used to provide information for decision making , Remote sensing products should be evaluated and evaluated according to the background of the decision
