Mapping India
summary
Gramener’s Reshaper is a Python library (GitHub: gramener/re-shaper) that moves data between overlapping Indian boundaries by computing polygon intersections and proportionally reallocating attributes using GeoPandas; it handles many‑to‑many district↔constituency transfers, creates PIN‑code areas via Voronoi tessellation, and produced an unofficial nationwide PIN shapefile around 2015. The redistribution assumes uniform population distribution within source polygons. Used operationally to map Muslim population from district to assembly level for Karnataka and to track village health metrics in UP, with measurable improvements reported.
