Functionalities:

• script for storing and retrieving credentials in a local file
• querying Copernicus Open Data Hub and retrieving Sentinel 2 images
• retrieving, plotting, and trimming images from the Sentinel 2 datasets
• finding a mapping from geo coordinates to pixel coordinates (coarse, but works)
• checking acquisition plans for a given location

Notes:

• Sentinel 2 image resolution is 10m per pixel, revisit time is 5 days.
• Copernicus data portal
• Copernicus data API
• Sentinel-2 acquisition plans
• Sentinel Application Platform - useful tool for initial visualization of data

Used libraries:

note: Development was done on Windows 10 and that's the system to which the installation notes apply

• rasterio - Also needed to be installed manually from here and required GDAL, which can be found here
• pillow is used to read JPEG2000 data. It uses OpenJPEG
