Hi all, 
First, I am super new to API and Python. Although I have gone through the documentations a bit, but my brain is more wired towards R programming and Google Earth Engine and can’t grasp the Planet way of data manipulation and access fast enough.

1. I had education and research account, but now I have the 30-day trial version of Insight plantform.
2. I have 400 circular polygons each with radius of 500m, in geojson format.
3. For each, I want PlanetScope (~3m) median NDVI .tif file for January 1st to March 31st of each year from 2016 to 2025.
4. I tried this in the Explorer awhile ago and ran out of my monthly quota before even finishing for one polygon for one season. It was downloading daily images instead of median for the season at say 30% cloud threshold, that would be super straight forward in Google Earth Engine.
5. There are a lot of secondary analses which I’ll have to do locally in R with all the images. So, I really need the images.

I am seeking for someone who can point me in the right direction so that I can handle the task.
 

Regards,

Wyclife
