Landsat8 SR Level2 数据文件夹内容

一、文件夹名称

（1）LC081230392015011001T1-SC20180705064729

         LC08||123039||20150110||01T1-SC||20180705||064729

        卫星数据类型||行列号||摄影日期||影像分类-产品简称||order的申请日期||order processing completed的时间

（2）卫星数据类型

        LC = Combined（both OLI and TIRS data）

        LO = OLI data only .   Pixel Size : OLI Multispectral bands 30 meters  ||   OLI panchromatic band  15 meters

    LT = TIRS data only    Pixel Size : TIRS Thermal bands: 100 meters (resampled to 30 meters to match                                                                             multispectral bands 

（3）产品分类Collection Category

         Tier1(T1) - 包括最高质量的Level-1 Precision Terrain(L1TP)地面数据，地理坐标已配准，误差满足(RMSE<12m）

         Tier2(T2) - 包括没有达到L1TP标准的影像，包括Level-1 Systematic Terrain(L1GT)和Systematic(L1GS)影像

         Real-Time(RT) - 尚未进行改正处理的新影像。

 

二、数据夹文件内容：

（1）共13个文件，分为三类：

        ①xml文件：可以看到影像的metadata，和各tif文件的文件名、pixel size、重采样方法、pixel的单位（如分类图的分类编号）

        ②文本文件：分为_ANG与_MTL两个

        _ANG Angle，是对影像的投影方式，等等数据的记录，应该可以拿来做几何

        _MTL _MeTadata File影像元数据介绍

        ③影像文件：均为tif格式，1-7 bands + _pixel_qa + _radsat_qa + _sr_aerosol
