Machine learning and gravity signals could rapidly detect big earthquakes

By Lurker,

Massive earthquakes don’t just move the ground — they make speed-of-light adjustments to Earth’s gravitational field. Now, researchers have trained computers to identify these tiny gravitational signals, demonstrating how the signals can be used to mark the location and size of a strong quake almost instantaneously.
It’s a first step to creating a very early warning system for the planet’s most powerful quakes, scientists report May 11 in Nature.
Such a system could help solve a thorny
How to combine multiple line feature into a single feature
By turuu0713,
How to combine multiple line feature into a single feature? How can this be done in ArcMap? Can only be selected and combined. But how to merge automatically? It doesn't dissolve
Esri Releases Updated Land-Cover Map with New Sets of Global Data

By Lurker,
Governments and businesses across the world are pledging to adopt more sustainable and equitable practices. Many are also working to limit activities that contribute to climate change. To support these efforts, Esri, the global leader in location intelligence, in partnership with Impact Observatory and Microsoft, is releasing a globally consistent 2017–2021 global land-use and land-cover map of the world based on the most up-to-date 10-meter Sentinel-2 satellite data. In addition to the new 2021
L3Harris High-Resolution Weather Instrument Set to Launch March 1 on NOAA’s GOES-T Satellite

By Lurker,

L3Harris Technologies third high-resolution weather instrument is set to launch March 1 onboard a NOAA satellite – strengthening the nation’s ability to monitor the environment and rapidly detect severe weather.
The Advanced Baseline Imager (ABI) is the primary instrument for the Geostationary Operational Environmental Satellite-T (GOES-T), the third in a series of four advanced geostationary weather satellites with L3Harris’ ABI onboard. The ABIs are controlled by L3Harris’ enterprise grou
The U.S. Geological Survey will make Landsat 9 data available from the Landsat archive beginning February 10, 2022

By Lurker,

At this time, USGS Landsat 9 Collection 2 Level-1 and Level-2 data will be made available for download from EarthExplorer, Machine to Machine (M2M), and LandsatLook. Initially, USGS will provide only full-bundle downloads. USGS will provide single band downloads and browse images, and Landsat 9 Collection 2 U.S. Analysis Ready Data shortly thereafter. Commercial cloud data distribution will take 3-5 days to reach full capacity.
The recently deployed Landsat 9 satellite passed its post-laun
