Study on Accuracy of Coastline Survey Based on Rational Function Model

Since rigorous sensor model, making useful of collinear function, can provide more accurate position determination and mature technology workflow, it has a widespread application, including an amount of digital productions of islands and coastline. Recently, rational function model, which does not depends any used sensor platform and type, has attracted more and more researchers. In this paper, we will first give the definition of this model, analyze its mathematic essences, and finally assess the accuracy difference between the new model and traditional rigorous model.
