    The 27.5-million-year cycle of geological activity

    Lurker
    By Lurker,
    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

    A satellite’s view of a deadly 2019 eruption could improve volcano monitoring

    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 sm

    A magnetic field reversal 42,000 years ago may have contributed to mass extinctions

    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 m

    Javad GNSS launches TRIUMPH-3 receiver

    By Lurker,
    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

    35 Differences Between ArcGIS Pro and QGIS 3

    Lurker
    By Lurker,
    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. Interfac
