We created Earth in Action to provide a lens into what's happening on our planet, as it happens. Whether it's something typical, like the current air temperature, or an extreme event like a major dust storm, we wanted to provide an opportunity for people to see them.
Along coastlines, where tides are typically magnified, they profoundly affect navigation, commerce, coastal flooding, water properties and sediment transport. Tides impact the flooding of rivers and, thus, influence the extent of their floodplain, which has cascading effects on biogeochemical and ecological processes.
The new Immersive Navigation mode introduces a detailed 3D map that includes buildings, overpasses, crosswalks, traffic lanes, traffic lights, and stop signs. Google bills this new mode as being the most significant update in over a decade to the app's driving experience. According to the American IT giant, the changes should help drivers stay focused and informed on the road, with Maps giving fresh, real-world information and natural directions.
Signals from Global Navigation Satellite Systems are quite vulnerable. They are exceptionally weak, meaning that any radio noise near their frequency, accidental or malicious, can interfere with reception. I am confident that there are people in every government who understand the problem. The challenge is getting leadership to both understand and act to reduce the risk.
St. Michael's College at the University of Toronto will host Mappa Mundi: Mapping the Mediaeval World, an in-person symposium exploring medieval cartography and how people in the Middle Ages visualized and interpreted their world. The event will take place Saturday, April 11, 2026. Hosted by Jacqueline Murray, the symposium examines mapping from two key angles: how medieval societies conceptualized the globe - including spherical representations of Europe, Asia and Africa, as well as mysterious regions beyond the known world -
If you did this, you were probably struck by one thing above all else: Greenland is huge. Freaking huge. It looks about twice as big as the U.S., roughly as big as North America and Central America combined. And despite the public waffling between saying we need it for its military or natural resource offerings, this is probably the reason Trump wants it.
We're introducing a new animated map engine built on top of ruby-libgd and libgd-gis. It allows Ruby applications to render real basemaps, draw GIS layers, and animate moving objects (cars, routes, planes) entirely on the backend - no JavaScript or WebGL required.
