| 摘 要： | 在森林资源监测过程中,特别是涉及林地变更工作时,遥感影像发挥了重要的作用。在实际工作中,上级部门下发的标准影像存在部分地区影像分辨率不高的问题,影响了林地变更工作的正常进行。为了拓展影像资源,使林地变更工作顺利进行,该文对Google Earth和天地图影像及校正配准后的精度进行比较研究,结果表明,配准前的Google Earth影像精度明显优于天地图影像;面积在1万hm^2及其以下的乡镇配准后的影像精度较高。

| Abstract: | Remote sensing image plays an important role in the process of forest resource monitoring, especially in the work of woodland change. In the actual work, the standard image issued by the superior department has the problem of low resolution in some areas, which affects the normal work of forest land change. In order to expand the image resources and make the woodland change work smoothly, a comparative study on the accuracy of Google Earth and sky map image and the corrected registration has been carried out. It is showed that the accuracy of Google Earth image before registration is significantly better than that of sky map image, and the image accuracy of township registration with an area of 10000hm2 and below is higher. |
