摘要
在人类活动和自然环境的影响下,海岸带长期处于变化状态,准确提取和实时监测海岸线变化对我国海岸带的利用与开发具有重要意义。文章利用Landsat TM遥感图像和ERDAS IMAGINE遥感图像处理软件的监督分类和图像增强方法,提出两种海岸线获取方法,完成海岸线的自动提取,实现海岸带的大面积同步和动态监测。
Under the influence of human activities and natural environment,the coastal zone has been in a changing status for a long time.Accurate extraction and real-time monitoring of coastline changes are of great significance for the utilization and development of China′s coastal zone.Using the supervised classification and image enhancement methods of ERDAS remote sensing image processing software and Landsat TM remote sensing image,two coastline extraction methods were proposed to complete the automatic coastline extraction and realize large-area synchronous and dynamic monitoring of the coastal zone in this paper.
