[0010] The present invention will be further described below in conjunction with the drawings and embodiments.
[0011] Reference figure 1 The problem to be solved by the present invention is to use the medium and high resolution vegetation remote sensing parameters obtained at time T1 to simulate the medium and high resolution vegetation remote sensing parameters at time T2. The implementation of this method requires two other types of data: (1) Medium and high resolution land use map Or vegetation type map; (2) Coarse resolution remote sensing data of time series.
[0012] Using data (1) Divide the types of vegetation coverage as much as possible, combined with the aggregation method of GIS, you can get the area percentage data of each type of vegetation coverage in each pixel at the coarse resolution, and then get the pure pixel of each type of vegetation coverage , And then combine the data (2) to extract the vegetation remote sensing parameter time series of each vegetation co...
