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
三、MTL文件内容：
