| 摘 要： | 真实性检验是利用现场观测数据或其他高质量遥感产品来获取待检验遥感产品精度的技术,是遥感产品制作及其应用的前提。通过分析均方根误差、平均绝对误差和平均相对误差等多种遥感产品精度评价统计量的适用性,确定了一套水色、水温遥感产品真实性检验流程。以中分辨率成像光谱仪(MODIS)海表温度(SST)遥感产品的真实性检验实例展示了文中确定的水色水温遥感产品真实性检验流程的可行性。分析结果表明待检验产品的分布规律(样本均值和标准偏差)对检验结果的统计量会产生一定的影响,平均值对平均相对误差的影响呈现高相关性。

| Abstract: | The aim of validation is to get the accuracy of satellite remote sensing products using cruise data or higher quality remote sensing products as the true data.It is necessary for the applications of remote sensing products.In this paper,we analyzed the applicability of various statistical algorithms for accuracy evaluation,including root mean square error,mean absolute error and mean relative error.Furthermore,we determine a practical validation process for ocean color products and sea surface temperature (SST) products.The validation results of SST derived from MODIS show that the provided validation process is feasible.The validation results also show the distribution of the products,which represented by the mean deviation and the standard deviation can lead to different validation results,and the mean value of sample is high correlative to mean relative error. |
