sentinelhub3.7相比3.4的版本，主要變化包括:
1. 增加對(duì)sentinel 基線04.00數(shù)據(jù)產(chǎn)品的支持；
2. 將aws數(shù)據(jù)下載模塊獨(dú)立出來
3. 原來的DataSource改為DataCollection
數(shù)據(jù)的組織結(jié)構(gòu)也發(fā)生了調(diào)整，新版的metafiles內(nèi)容包括：

注意，只有使用productid下載（Awsproductrequest）才能下載到與歐空局相同文件結(jié)構(gòu)的數(shù)據(jù)，包括元數(shù)據(jù)。而通過tilename、date和awsindex下載的方式（只是根據(jù)AWS S3的數(shù)據(jù)組織結(jié)構(gòu)來獲取數(shù)據(jù)），獲取到的元數(shù)據(jù)不全，尤其是記錄有DN值轉(zhuǎn)換反射率的信息數(shù)據(jù)是獲取不到的。由于sentinel 處理基線04.00的發(fā)布，新版L2A數(shù)據(jù)的反射率計(jì)算方式發(fā)生了重大變化，所以要用sentinelhub3.5.0以上的版本，并且只能使用productid進(jìn)行下載。
