Abstract

Researches have demonstrated that the linear features of the cultivation land usually have exaggerative appearance on SARimages, which will affect the accuracy of crop mapping on SARimages. In this study, the authors measured lots of widths at the half brightness of linear features such as channels, dykes, roads and ridges in rice fields on SARimages, and then made comparisons with results of field investigation. On such a basis, the probability distribution of widths at half brightness of linear features and the cultivation land coefficients for rice field mapping were calculated, which could give necessary correction and hence improve accuracy in rice area mapping. Some suggestions for further researches are also put forward.
