采用MagellanProMARKX -CM手持GPS接收机 ,以广东省湛江市通明海湾为实验区 ,通过野外实地数据采集、室内数据差分后处理、与TM影像配准等 ,探索了一套GPS与遥感图像分析相结合 ,快速、准确更新沿海围垦动态数据的工作流程 结果表明 :GPS应用于TM影像几何纠正 ,可提高TM影像几何纠正的精度 ;GPS采集的数据可以辅助目视解译 ,提高目视解译精度 ;GPS可以补充TM影像成像后最新的动态信息
Using MagellanProMARKX-CM handheld GPS receiver, taking the Tongming Bay of Zhanjiang City, Guangdong Province as an experimental area, a set of GPS and remote sensing image analysis was explored through field data collection, indoor data differential post-processing and TM image registration. The results of the workflow of fast and accurate updating of dynamic data of coastal reclamation show that GPS is applied to the geometric correction of TM images and can improve the accuracy of TM image geometric correction. The data collected by GPS can help visual interpretation and improve the accuracy of visual interpretation. GPS can complement the latest dynamic information after TM imaging
