Abstract: On the basis of the two accustomed methods about detecting land-use change, that is, imagery enhancing and post-classification comparison, this paper proposed a new method, overlaying land-use map on remote sensing imagery to detect land-use change. This study used degree 2 Polynomial and cubic convolution to proceed geometric correction on remote sensing image, and verify its accuracy. Then, land-use map was overlaid on the remote sensing image to compare land-use between the two phases and to detect land-use change during the two phases.
