如果想下载NASA/USGS Landsat-8 和 ESA Sentinel-2的免费图像和快速处理,
这里的软件可以一试
Unique image fusion software to rapidly process images from Landsat-8, Sentinel-2, QuickBird, WorldView-3, etc.
Landsat-8:
The U.S. Geological Survey (USGS) distributes daily Landsat-8 data in three very accessible ways:
- Search and bulk-download data - EarthExplorer - EarthExploreruseful tutorial
- Browse and download data - GloVis - USGS Global Visualization Viewerdemo
- View and get colour images - LandsatLook Viewer - LandsatLook Viewer
Recently, there are other avenues to download Landsat-8 imagery, e.g.
- Libra by Development Seed Libra
- Landsat-8 imagery data (compressed separate bands) also available via Amazon Web Services (AWS)

Sentinel-2
Methods of downloading Sentinel-2 Level-1C data
After knowing the granule / tile name for an AOI, one can start to download Sentile-2 imagery data right away. The most easy way would be using the Method 2 introduced below.
Method 1:ESA's Sentinels Scientific Data Hub, or directly, map-based imagery search tool (to download large-sized whole scenes, typical file size ~7 GB)
Method 2 :Sentinel-2 on Amazon Web Services (AWS) S3: including an easy-to-use map-based imagery search tool (to download individual granules / tiles or whole scenes, no registration required)
The public bucket for the imagery data on AWS is:sentinel-s2-l1c.http://s3-website.eu-central-1.amazonaws.com (The User Guide below contains some practical info on how to quickly download data by folders, not single files one by one, from AWS S3)
Method 3: Via the USGS portals - The News "USGS Partners with European Space Agency to Deliver Copernicus Earth Data" (to download data at granule / tile level)
Method 4: Sentinel-2 on Google Earth Engine (search "Sentinel-2: MultiSpectral Instrument (MSI), Level-1C" there)
