Hi all,
A long standing request from partners has been to get village-level stats like on LULC changes, water availability, etc. which have otherwise been available pre-computed on the CoRE stack at MWS units instead. Aaman, Saksham, and team from IIIT Delhi as part of a software engineering course run by Professor Pankaj Jalote, and with inputs from FOSS United, have built CSVAT for village-level analytics. This should just be a simple drop on AWS to get it going for everyone -- it uses the public APIs and published datasets for everything, a perfect example of how to build new use-cases on underlying published artefacts. Check out their methodology page for details.
The app is actually an excellent way to explain different kinds of computing environments that can be set up. It allows you to specify whether you want to do client-side compute or server-side, i.e. if you are on a poor network or low-end machine then you want the server to fetch data from the CoRE stack and run computations and just send the results to the browser, else your browser can fetch all the data and compute and render. The frontend option is of course also ideal for interactive dashboards which can be enhancements to build in the future.
The app also allows you to specify whether you want exact stats or approximations are fine. Exact stats fetch underlying LULC and other rasters, do intersections on village boundaries, and compute stats like % of area under crops and so on, which is of course somewhat compute intensive. Appox stats use the MWS-level pre-computed stats, and provided a weighted average for a village by intersecting it with overlapping MWSes. So this will also help bring out use-cases for which exact village-level stats are actually needed and approximations are not adequate.
