2009/11/23
对柴达木地区涩北气田地质地理环境下的蚀变矿物进行分析，结合卫星高光谱遥感数据Hyperion的图谱，对已知气田区与背景区光谱特征进行相关分析，确定了932.64~1 346.25 nm与2 002.06~2 385.5 nm为油气信息识别的有利波长范围； 利用光谱角制图（SAM）技术提取了涩北气田油气的空间分布信息和台吉乃尔含气构造等远景区，为高光谱遥感油气勘探提供了有效技术方法与途径。
基于Hyperion数据的太湖水体叶绿素a浓度遥感估算
高光谱 Hyperion数据 水质遥感 混合光谱分析 太湖
2008/10/21
通过对2004年8月19日太湖Hyperion高光谱遥感数据的处理和分析，文章首先采用比值和一阶微分处理技术进行了叶绿素a浓度的估算. 为了弥补此两种方法在模型的适用性和通用性方面的不足，本文尝试了利用混合光谱分析模型进行太湖水体叶绿素a浓度的提取和成图. 实验结果说明高光谱遥感数据Hyperion可以进行水体叶绿素a浓度的监测，并且作为高光谱处理技术之一的混合光谱分析技术是水体叶绿素a浓度估算的...
