| Abstract: | This paper analyzed the distinction uncertainty in land ,classification. According to the theory of Rough sets,the model of land distinction uncertainty and accuracy estimate were presented. The certainty distinction accuracy and uncertainty accuracy were expressed by the estimate, its variation rule was discussed. |
