EarthViewer vs TrueSize

What did Earth’s continents and oceans look like 250 million years ago, or even 1 billion years ago? What do we know about the climate back when our planet formed? How has sea level changed since the melting of the last ice age and what does the future hold? EarthViewer is like a time machine for exploring Earth’s deep history. Based on the latest scientific research, it lets you scroll through the last 4.5 billion years with your fingertips. Follow a favorite landmark, be it Greenland or New York City, as its position shifts through time, or watch a famous fossil like Tiktaalik make an incredible journey from its origin to its current location. Layer your view of shifting continents with data on atmospheric composition, temperature, biodiversity, day length, and solar luminosity, to get a more complete view of our dynamic planet. EarthViewer features include: • Continental reconstructions and accompanying data dating back billions of years • Sea level maps for the last 21,000 year and for 8,000 years into the future • Global temperature maps for the last 100+ years • Ability to manipulate the globe and zoom to any location • Locations of modern cities tracked back over 500 million years • In-depth features on major geological and biological events in Earth history • Clickable details on geologic eons, eras, and periods • Automated play modes • Animations between globe and flat map projections • Extensive reference list • Suggestions for classroom use The Howard Hughes Medical Institute (HHMI) is a non-profit medical research organization that ranks as one of the nation’s largest philanthropies. HHMI’s BioInteractive initiative opens a window on cutting-edge science through interactive web features, short films, virtual labs, and scientific animations. Since teachers play a pivotal role in launching the careers of future scientists and in helping the public understand the beauty and import of science, the BioInteractive team partners with the teaching community to create and distribute media that is engaging and relevant to the science curriculum.

Perfect For • Students learning geography and map accuracy • Teachers explaining map projection distortion and how borders changed through history • Travelers visualizing distances and regions • Geography enthusiasts exploring historical and modern borders • Language lovers discovering where the world's languages are spoken • Anyone curious about the real scale of our world Why TrueSize? Traditional flat maps can significantly distort the apparent size of countries and regions, especially near the poles. TrueSize uses spherical geometry to provide more realistic size comparisons while letting you freely move and explore territories around the globe. From the creators of TrueSize.net, the official TrueSize app brings interactive geography tools, hundreds of thousands of regions, a historical timeline, population and language maps, games, measurements, and custom geographic data to your device. Rediscover the world as it truly appears – clearly, accurately, and interactively.
