Spatiotemporal Interpolation and Cross Validation Based on Product-Sum Model

  • In this paper,firstly,the expression of spatiotemporal is implemented;secondly,spatiotemporal product-sum model is analyzed and deduced into another one which can be calculated;thirdly,the spatiotemporal weight coefficient matrix based on ordinary kriging is put forward and the spatiotemporal interpolation is done based on this matrix;lastly,the performance of spatiotemporal interpolation is tested by cross validation.The experiment shows that spatiotemporal interpolation researched in here can provide more information on spatiotemporal random domain with some certain accuracy so as to achieve the spatiotemporal interpolation results.
