In order to conveniently and rapidly develop the algorithms for remote sensing products or remote sensing image processing,the basic idea is using some of the existing algorithms to develop new algorithm in the form of "building blocks".Due to the algorithm dependency,the algorithms are called one by one,which means the process flow of remote sensing products.In this paper,a visual dataflow model is presented for the production of remote sensing products,which can represent the process flow of remote sensing products.The proposed model can reflect not only the relationship between algorithms,but also the number of algorithm to be called and the information of data to be processed.Using this model,the changes of the process flow can be described conveniently and the concurrent execution of the algorithm can be performed.
