8 billion in columns (3D)
7.84 billion people as columns on the globe (GHS-POP, 2020, 0.25° grid). The "share of humanity" slider lights up the densest cells: half of all people live on 2.1 % of the land — the sparsest half of the land carries 0.05 %.
Geography & earth scienceTry itAMOC tipping point (3D)
The Atlantic overturning circulation on a 3D globe: more freshwater weakens it until it tips, and turning back alone does not restore it. Stommel box model with hysteresis, meridional section and temperature effects for Europe.
Geography & earth scienceTry itThe breathing city
Explore Berlin in 3D with official buildings and modeled urban climate: air and surface temperature, thermal stress and nighttime cooling.
Geography & earth scienceTry itGlobe (3D)
Photo-realistic Earth with detailed country borders, ~200 capitals and major rivers — click a country/city, search, zoom, with live clouds and atmosphere.
Geography & earth scienceTry itMeander simulation
In time-lapse, a river winds across a flat floodplain. The cut bank is eroded and a sandbar grows on the point bar until a cutoff severs a loop and leaves an oxbow lake behind. Cross-profile with secondary flow, erodibility, valley slope and bank protection are adjustable.
Geography & earth scienceTry itMercator and map projections
Compare a globe with a flat map, explore polar area distortion and Tissot’s indicatrices, and move Greenland towards the equator to reveal its scale.
Geography & earth scienceTry itPlate tectonics
Explore divergent, convergent and transform boundaries in 3D. See mantle convection, seafloor formation, subduction, mountains and earthquakes, plus continental drift over time.
Geography & earth scienceTry itWeather stations
Explore roughly 500 German weather stations on a 3D map. Select a station for temperature, rainfall, wind and other charts using Bright Sky and DWD open data.
