How to extract NDVI time-series values for a specific area of interest from Sentinel-2 live data?
I am working on a real-time dashboard project in ArcGIS Online where I have integrated Sentinel-2 live data and applied NDVI analysis using Process Templates.
Now, I need to extract zonal statistics of NDVI over time for each parcel or pivot in my dataset. My goal is to generate a time-series of NDVI values per polygon so I can visualize changes or perform further analysis in the dashboard.
I would like to know:
1. How to automate the extraction of time-series zonal statistics in ArcGIS Online
2. Which tools or workflows are recommended for handling multiple polygons over multiple dates from live Sentinel-2 imagery.
3. How to export or link the results back to my dashboard for visualization.
