How I searched for the hottest villages in Kerala with Microsoft's Planetary Computer

[Shijith Kunhitty]

Just wanted to plug my data story on villages in Kerala and how hot they get. 

The story is at https://shijith.com/blog/kerala-panchayat-temp/ 

And the code is at https://github.com/shijithpk/hottest-panchayats-kerala 

Was thinking of using Google Earth Engine for this story, but decided to go with Planetary Computer since it's Python-centric and I'm more familiar with that language.

Pretty sure earth/environment science guys won't be happy with my methodology, but hopefully there's enough of a logic to it to accept the story as a basic analysis.

Thanks! -shijith

Awesome stuff! Can it be extended to all Panchayats in the country easily?

Just a nitpick: why not use "median" as an averaging strategy? 

best,

Thanks for the comments Dilawar! To answer your questions:

I guess so, just have a feeling that services like Planetary Computer might not be able to handle all the data and could crash if you don't code it in a certain way. Planetary Computer allows you to create something called dask clusters to 'perform computation in parallel and at scale'. I'm an amateur coder, so I don't how to do all that magic, think you need to do all that for operations to complete without crashing.

Just a nitpick: why not use "median" as an averaging strategy? 

No strong reason really, i'm just thinking that since this is a story about how hot villages get, about temperature extremes, you need a measure of central tendency like average that takes in ALL values, instead of a measure like median that ignores extreme values.

Hi Shijith,

Really good work putting so many things together, this can be a good reference material for how to fetch and use data from these various sources. Many different technologies / techniques brought together here.
