PujoPath — Transit & Geospatial PWA
Progressive web application providing interactive GIS transit navigation and crowd route mapping across Kolkata Metro corridors.
Project Overview
During peak cultural festivals in Kolkata, millions of transit commuters navigate complex urban corridors with congested streets and intermittent mobile network connectivity. Commuters need fast, offline-capable route guidance and transit station mapping.
What It Does
A progressive web application combining interactive OpenStreetMap GIS visualizations with Kolkata Metro route mapping. It caches essential geospatial data client-side, enabling fast location discovery and route planning even in low-bandwidth or offline environments.
