Smart Cities Mission Data Portal

A surprisingly obscure portal — 100 Indian cities contribute datasets on air quality, water supply, solid waste, mobility, housing, safety, and urban finance. The platform uses the same CKAN-based infrastructure as data.gov.in, meaning datasets are API-accessible. Particularly valuable for cross-city comparisons and for finding data from tier-2 cities that rarely publish structured open data. The Smart Cities Mission has a separate dashboard at smartcities.gov.in for project-level progress tracking.
