摘要
从卫星遥感影像中快速、准确地提取水体信息已经成为水资源调查、水资源宏观监测、城市绿化度调查及湿地保护的重要手段。针对HJ—1A/B(中国环境一号卫星)影像与Landsat ETM(美国陆地探测卫星)影像的相似性,利用水体特有的光谱特性,采用多种水体提取方法对HJ—1A/B影像中水体信息进行了快速提取,并比较了两种影像水体提取结果。总结了在环境一号卫星影像中进行水体提取的精度影响因子。分析了传感器、分辨率、水体提取模型对水体提取的影响。
Extracting water information from the satellite remote sensing images quickly and accurately has become important method for water resource investigation,water monitoring,urban greening water resources survey and wetland protection.According to the similarity between Chinese HJ—1A/B and American Landsat ETM,using the spectrum characteristics of water,adopting several water extraction methods to extract water from the two images quickly,comparing the water extraction results from the two images,summarizing the influence factors of water extraction accuracy,analysing the sensors,the resolution,the water extraction models which influence water extraction from HJ—1A/B.
