土地利用现状图与遥感图像叠加进行土地利用变更监测

Detecting Land-Use Change by Overlaying Land-Use Map on Remote Sensing Imagery

摘要: 在土地利用变更遥感监测常用的两种方法，即图像增强法和分类后比较法的基础上，提出了一种基于土地利用矢量图与遥感图像叠加探测土地利用类型变化的方法。采用二元二次多项式和三次卷积法进行几何精校正，通过验证，拟合方程的精度与有效性均合乎要求，在几何精校正后将土地利用现状图叠加到校正后的遥感图像上，通过叠加比较可找出土地利用类型变化信息，并可检测出原土地利用现状图的误差。

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.
