利用Landsat ETM+分析城市热岛与下垫面的空间分布关系
城市热岛 下垫面 热红外遥感
2009/11/20
采用数理统计与空间统计相结合的方法，利用Landsat ETM+数据对北京、上海、沈阳和武汉等4个大城市的夏季城市热岛相对强度与城市下垫面的空间分布关系进行对比研究。用混合像元线性光谱分解方法提取的城市植被覆盖度与不透水面表征城市下垫面；用城市地表亮温与水体亮温差值表征城市热岛相对强度。结果显示，4个城市的植被覆盖、不透水面与热岛强度的分布呈较强的空间正自相关，并且存在较为一致的自相关范围，该范围...
利用Landsat TM6数据反演大亚湾海水表层温度
大亚湾 海表温度 陆地卫星
2009/11/20
基于Landsat TM6数据，采用覃志豪单窗算法（MW）、Jiménez-Mun~oz单通道算法(SC)和Weng算法计算了大亚湾海域的海表温度（Sea Surface Temperature，SST），分析比较了3种算法反演的海温空间分布特征，并选取12个样本点与实测数据进行了比较。结果表明： 3种算法反演的海温分布特征基本一致，在3幅海温图像上可以清晰地观察到大亚湾核电站的热废水扩散特征； ...
