Hello! The AWS CLI is going to be only related to the storage of the data, it has no knowledge of any geospatial functionality. I’d recommend at looking at a service like https://www.sentinel-hub.com/ which can help with a lot of these concepts.

You might also find that EO Browser (which uses Sentinel Hub services) fits your purpose nicely: https://apps.sentinel-hub.com/eo-browser/

You can upload your area od interest and then either download images of NDVI values over the area (for a selected date) or draw a chart that shows how NDVI values change over time.

Hi @wfjoubert,

I suggest you check the following examples:
https://docs.sentinel-hub.com/api/latest/#/data/Examples_for_S2L2A?id=exact-ndvi-values-using-a-floating-point-geotiff
https://docs.sentinel-hub.com/api/latest/#/data/Examples_for_S2L2A?id=exact-ndvi-values-using-a-floating-point-geotiff

These are using Sentinel Hub API rather than CLI library, but they are doing exactly what you want…
