A high-resolution map created by combining satellite data and physics-based modeling reveals Antarctica’s buried bed beneath the ice, uncovering tens of thousands of subglacial features and a massive under-ice channel in the Maud Subglacial Basin, improving understanding of how the ice sheet may move over time.
A new ultra-high-resolution map of Antarctica’s bedrock beneath the ice combines satellite data and glacial-flow models to reveal a surprisingly varied subglacial landscape—from alpine valleys to eroded ice-stream troughs. Published in Science by Helen Ockenden and colleagues, the map refines projections of ice loss and sea-level rise beyond earlier radar surveys. The work highlights the importance of space-based data for understanding Antarctica, with a caveat that removing ice weight would cause the land to rebound."
Researchers from Princeton and the University of Arizona created a high-resolution, AI-driven map of groundwater depth for the continental United States by combining over a million direct measurements with regional climate and geological data. The result estimates about 306,000 cubic kilometers of groundwater at a 30-meter grid (roughly 98 feet), revealing shallow supplies previously unknown and enabling more informed irrigation, conservation, and water infrastructure decisions. The model also quantifies uncertainty at each location and is designed for global expansion via the HydroFrame platform, signaling a shift toward data-driven, local-scale groundwater management.
A new, highly detailed map of Antarctica’s bedrock beneath the ice, created by combining satellite surface data with ice-flow physics, reveals thousands of previously unseen hills and ridges and a prominent 50m-deep, 6km-wide channel in the Maud Subglacial Basin; while uncertainties remain, the map offers a clearer view of the bedrock that could improve models of glacier movement and future sea-level rise, complementing radar surveys and aiding climate projections.
Emilia Doda created an open-source map showing planned data centers across Pennsylvania to inform residents and promote transparency, highlighting the growing digital infrastructure and community involvement in technological development.
The article discusses the evolving and increasingly complex nature of mapping Ukraine's front line in the ongoing conflict with Russia, highlighting how open-source maps and social media are crucial in understanding battlefield dynamics, especially as the front becomes more porous and contested, with both sides using maps for propaganda and strategic purposes.
A new digital map called Itiner-e reveals that the Roman road network was over 60,000 miles longer than previously thought, encompassing nearly 186,000 miles of roads across Europe, the Near East, and North Africa, providing new insights into the connectivity and power of the Roman Empire.
A team of international researchers has created a detailed map of the Roman road system around AD 150, covering over 300,000 km, which offers new insights into ancient Roman connectivity, travel, and influence, despite many roads still being uncertain in exact location. The visualization tool supports further research into Roman infrastructure and its long-term effects on the empire and beyond.
Zealandia, a largely submerged landmass beneath the Pacific Ocean, has been officially recognized as Earth's eighth continent after comprehensive mapping and research, revealing its unique geological features and history as part of Gondwana, with advanced technology enabling detailed exploration of its underwater terrain.
Google Earth has introduced a new feature allowing users to view historical Street View images, enabling them to see how locations have changed over time, as part of its 20th anniversary updates. Additionally, professional users will soon gain access to AI-driven insights about environmental factors like tree canopy coverage and land surface temperatures.
A new nationwide coordinating system for studying altitude will lead to changes in the listed elevations of Colorado's 14ers and the capitol steps marker in Denver, as the study shows discrepancies in their heights. The federal government will switch to this new system in 2026, impacting mapping across the country, and the study, led by a scientist at the National Oceanic and Atmospheric Administration, has taken 15 years and will redefine the American Vertical Datum.
Google Maps has added a "show 3D buildings" option for navigation in its latest update, providing basic 3D geometry of buildings while navigating. This visual tweak follows a series of recent additions to the app, including weather and air quality display, AI-related upgrades, and real-time battery info for electric vehicles.
The exact location of the fire burning on the United States Air Force Academy in Colorado Springs has been pinpointed using a photo shared by the Colorado Springs Fire Department and analysis with Google Earth. The fire is near the mouth of the West Monument Creek canyon, approximately 1.64 miles from the northern most homes of Peregrine and 1.6 miles from the Military Family and Readiness Center on the Academy. Wind gusts have been out of the west through Sunday afternoon at speeds between 35 and 45 mph.
Scientists have completed the first comprehensive mapping of New Zealand's Lake Rotorua, uncovering ancient features and a peculiar magnetic anomaly. The maps reveal thousands of pockmarks on the lake's floor, evidence of an ancient river, and magnetic anomalies that suggest the presence of another hydrothermal system beneath the lake. This mapping provides new insights into the lake's geological history and hydrothermal processes, shedding light on the violent volcanic activity that formed the lake 200,000 years ago.
Zealandia, the largely submerged continent near New Zealand, has been completely mapped by a team of geologists using rock samples and geophysical mapping methods. The continent, twice the size of India, was likely flooded around 40 million years ago. The mapping revealed large sandstone formations and basaltic rock pebbles, providing insights into Zealandia's geological history. This discovery sheds light on a previously unknown part of Earth's geography and geological evolution.
