  2. Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a 'pulse,' according to a new study published in the journal Geoscience Frontiers. "Many geologists believe that geological events are random over time. But our study provides statistical evidence for a common cycle, suggesting that these geologic events are correlated and not random," said Michael Rampino, a geologist and professor in New York University's Department of Biology, as well as the study's lead author. Over the past five decades, researchers have proposed cycles of major geological
  3. On December 9, 2019, a cloud of steam and volcanic gases blasted out of New Zealand’s Whakaari, or White Island, volcano. Relative to eruptions at other volcanoes, the explosion was small. But it claimed the lives of 22 people and injured another 25, many of whom suffered severe burns. Now, using high-resolution satellite data and computer algorithms, scientists have revealed how gases released by the volcano subtly changed before, during and after the 2019 eruption. Observing such small changes using satellites could greatly improve volcano monitoring and help spot early warnings o
  4. A flip-flop of Earth’s magnetic poles between 42,000 and 41,000 years ago briefly but dramatically shrank the magnetic field’s strength — and may have triggered a cascade of environmental crises on Earth, a new study suggests. With the help of new, precise carbon dating obtained from ancient tree fossils, the researchers correlated shifts in climate patterns, large mammal extinctions and even changes in human behavior just before and during the Laschamps excursion, a brief reversal of the magnetic poles that lasted less than a thousand years. It’s the first study to directly link a magnet

  8. Javad GNSS has launched the TRIUMPH-3 receiver for surveyors and geodesists. It is capable of efficient tracking even in difficult conditions. It can track all current signals and is ready for any future satellites. TRIUMPH-3 is designed to operate as a base together with TRIUMPH-LS and TRIUMPH-LS Plus to efficiently accomplish any geodetic job. Its real-time kinematic (RTK) system communicates via integrated UHF, 4G/LTE, Wi-Fi and Bluetooth channels, and eliminates the need to subscribe to a real-time network for corrections. The new powerful and reliable receiver for high-precision
  9. Six years ago, we compared ArcGIS vs QGIS. The response was incredible and we thank you for that. But since then, the game has changed. Yet, the players are still the same. The Omen of Open Source GIS is back with QGIS 3. It’s up against the Pioneer of Proprietary GIS, ArcGIS Pro. Buckle up. Because today, you’re going to witness a head-to-head battle between the juggernauts of GIS software. Pick your poison. Table of Contents 1. 3D 2. Interface 3. Coordinate Systems 4. Catalog 5. Editi
  10. The topic that counts is interesting and that is the way to do good work when we have to present a project. Unfortunately for us that we do not have a solution like Erdas. The Hexagon company evolves every day and presents many solutions but at the business level, it talks about opportunities for students but I do not know their prices. Esri at least provides an opportunity and we know it costs. Thanks for your comments and any ideas to bring that workflow into cheaper or open access solutions. Lurker successes.
  11. When it comes to choosing the right geospatial data for any project, many factors come into play—cost, convenience, consistency, and resolution, to name a few. Depending on the application, these factors can outweigh one another in importance. Above all, one critical factor to never overlook is accuracy. Data accuracy is the degree to which information on a map matches real-world values. When it comes to geographic information systems (GIS) and artificial intelligence (AI) applications, positional accuracy plays a vital role in the precision of the mapped assets or derived vector data.

  16. In the middle of last year, Google announced that it was turning Android phones into an early earthquake alert system. The system was first deployed in California which already has a sophisticated network of seismometers in place. In California, the Android Earthquake Alerts System disseminated alerts from the existing ShakeAlert system, but in regions that don’t have seismometer networks, Google said that users could opt in to turn their Android phone into a mini seismometer. Today, Google has announced that Greece and New Zealand will be using the Android Earthquake Alerts System for both de
  17. These mysterious earthquakes originate between 400 and 700 kilometers below the surface of the Earth and have been recorded with magnitudes up to 8.3 on the Richter scale. Xanthippi Markenscoff, a distinguished professor in the Department of Mechanical and Aerospace Engineering at the UC San Diego Jacobs School of Engineering, is the person who solved this mystery. Her paper "Volume collapse instabilities in deep earthquakes: a shear source nucleated and driven by pressure" appears in the Journal of the Mechanics and Physics of Solids. The term deep-focus earthquake refers to the fac
  18. Does anyone know about any good alternative to tinypic? I need to upload and host images in high quality.
  19. While the concept of “deepfakes,” or AI-generated synthetic imagery, has been decried primarily in connection with involuntary depictions of people, the technology is dangerous (and interesting) in other ways as well. For instance, researchers have shown that it can be used to manipulate satellite imagery to produce real-looking — but totally fake — overhead maps of cities. The study, led by Bo Zhao from the University of Washington, is not intended to alarm anyone but rather to show the risks and opportunities involved in applying this rather infamous technology to cartography. In fact t

  21. From space, large decks of closely spaced stratocumulus clouds appear like bright cotton balls hovering over the ocean. They cover vast areas—literally thousands of miles of the subtropical oceans—and linger for weeks to months. Because these marine clouds reflect more solar radiation than the surface of the ocean, cooling the Earth's surface, the lifetime of stratocumulus clouds is an important component of the Earth's radiation balance. It is necessary, then, to accurately represent cloud lifetimes in the earth system models (ESM) used to predict future climate conditions. Turbulence—ai

  24. The rate of sea-level rise in the 20th century along much of the U.S. Atlantic coast was the fastest in 2,000 years, and southern New Jersey had the fastest rates, according to a Rutgers-led study. The global rise in sea-level from melting ice and warming oceans from 1900 to 2000 led to a rate that's more than twice the average for the years 0 to 1800—the most significant change, according to the study in the journal Nature Communications. The study for the first time looked at the phenomena that contributed to sea-level change over 2,000 years at six sites along the coast (in Connec
