Estimate: A digital surface model: trees and roofs are in the heights. Relief exaggeration is printed on the stage.
• Hospitals Hospitals as mapped, each as one point with its name and, where tagged, the operator type, bed count, emergency tag and speciality. (c) OpenStreetMap contributors. Available under the Open Database License (ODbL). OpenStreetMap as of 2026-07-24. Estimate: Mapped hospitals only; bed counts are rare and as tagged; no capacity, occupancy or quality is implied.
• People per cell, WorldPop 2020 People per cell in 2020, summed from the national 1 km raster onto a 100 by 90 grid of about 490 by 550 metres, drawn as columns with a quantile legend; click a cell to read it. WorldPop (www.worldpop.org), University of Southampton, 2020 UN-adjusted 1 km, CC BY 4.0; summed per cell by the Academy build. read 2026-10-17. Estimate: A modelled 2020 estimate adjusted to UN totals; never a count of people affected; cells outside the national file are empty.
• Population density, GPW v4.11 (2020) People per square kilometre in 2020, draped on the terrain as context for the count columns. Population: CIESIN, Columbia University, Gridded Population of the World v4.11 (2018), NASA SEDAC, CC BY 4.0. Live: this page requests gibs.earthdata.nasa.gov when the layer is opened; the data date is read from static:2020 and printed with it. We acknowledge the use of imagery provided by services from NASA's Global Imagery Browse Services (GIBS), part of NASA's Earth Science Data and Information System (ESDIS). Estimate: Exposure context only; a 2020 estimate, never a count of people affected; a static product, the year 2020 is printed.
• Air quality, Copernicus CAMS via Open-Meteo (hourly, 5 days) Hourly PM2.5, PM10, nitrogen dioxide and ozone from the CAMS global model at the clicked point, five days from the request; the first chart opens at Connaught Place. Weather data by Open-Meteo.com (CC BY 4.0); air quality: Copernicus Atmosphere Monitoring Service (CAMS). Live: this page requests air-quality-api.open-meteo.com when the layer is opened; the data date is read from hourly.time and printed with it. Estimate: Model output at about 40 km resolution, not monitor readings; never a warning; the reference line is the WHO 2021 guideline, not a local standard.
• Nitrogen dioxide column, TROPOMI (Sentinel-5P) Tropospheric nitrogen dioxide column for the day shown, draped on the terrain. TROPOMI tropospheric nitrogen dioxide column, ESA Copernicus Sentinel-5P (contains modified Copernicus Sentinel data), via NASA GIBS, with the product date. Live: this page requests gibs.earthdata.nasa.gov when the layer is opened; the data date is read from layer-time-actual and printed with it. We acknowledge the use of imagery provided by services from NASA's Global Imagery Browse Services (GIBS), part of NASA's Earth Science Data and Information System (ESDIS). Estimate: A column amount, never a ground-level concentration or a health warning.
• Surface air temperature, AIRS (daily, day) Daytime surface air temperature for the day shown, the heat layer of the twin. AIRS L3 surface air temperature (day), NASA, via NASA GIBS, with the product date. Live: this page requests gibs.earthdata.nasa.gov when the layer is opened; the data date is read from layer-time-actual and printed with it. We acknowledge the use of imagery provided by services from NASA's Global Imagery Browse Services (GIBS), part of NASA's Earth Science Data and Information System (ESDIS). Estimate: A satellite retrieval at about 1 degree; not a station reading and not a heat warning.
• Urban heat island, summer daytime 2013 The 2013 urban minus rural summer daytime surface temperature difference. CIESIN, Columbia University, and NASA SEDAC: Global Urban Heat Island (UHI) Data Set, 2013. Live: this page requests gibs.earthdata.nasa.gov when the layer is opened; the data date is read from static:2013 and printed with it. We acknowledge the use of imagery provided by services from NASA's Global Imagery Browse Services (GIBS), part of NASA's Earth Science Data and Information System (ESDIS). Estimate: A 2013 static product; the city has grown since; the year is printed.
• Built-up and settlement extent, HBASE 2010 Built-up extent in 2010 from Landsat, draped on the terrain. CIESIN, Columbia University, and NASA SEDAC: Global Human Built-up And Settlement Extent (HBASE) 2010.

We acknowledge the use of imagery provided by services from NASA's Global Imagery Browse Services (GIBS), part of NASA's Earth Science Data and Information System (ESDIS). Estimate: A 2010 classification; the year is printed.

Why this place: One box of about 49 by 50 kilometres holds the densest part of a metropolitan region of more than thirty million people, with winter air pollution among the highest measured in any city, extreme pre-monsoon heat, a mapped hospital network and a strong urban heat island, so exposure, environmental health and health-system capacity can be taught where the signals are largest. Data quality: WorldPop and GPW v4 give the count and density, HBASE the built-up extent, the Copernicus CAMS air-quality forecast through Open-Meteo answered 178.8 micrograms per cubic metre of PM2.5 for the first hour of 17 October 2026, TROPOMI nitrogen dioxide and AIRS surface air temperature are daily via GIBS, and OpenStreetMap maps the hospitals. It connects to the pollution-environmental-health, public-health-emergencies, health-systems, human-development and work-skills disciplines of the atlas.
