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

The Critical Role of Geospatial Data Accuracy
By Lurker,
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, po
Android phones now show earthquake alerts in Greece and New Zealand
By Lurker,
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

Unmanned Aerial Remote Sensing: UAS for Environmental Applications is an excellent resource for any practitioner utilising remote sensing and other geospatial technologies for environmental applications, such as conservation, research, and planning. Students and academics in information science, environment and natural resources, geosciences, and geography will likewise find this comprehensive book a useful and informative resource. https://mega.nz/file/TJxUASrY#uWgJOmJ05WUmkTBOQUsCDZFO6x1Gwc81Nkk29QDSyi8 -
really nice storymaps my friend, btw, what is your current licence for your arcgis storymaps? https://doc.arcgis.com/en/arcgis-storymaps/reference/licensing.htm

Dear GIS users/colleagues, I have been learning how to use GIS and more specifically ArcGIS for more than a year (online course). I was able to build in my free time a portfolio of maps on topics which interest me or are related to my area of expertise. I displayed most of them in a StoryMap online, which I intend to use as my online portfolio to showcase my work to potential future employers. The only issue is that, my ArcGIS licence is expiring soon (end December/early Jan). I contacted ESRI and they confirm that I am definitely going to loose all my content, StoryMaps included. Here is the StoryMap link, it's public anyway ;) https://storymaps.arcgis.com/stories/51b554201f464aea842d201c0020d88d After a bit of research, I was able to find a way to copy a StoryMap from one account to another, with a Python script. I tested it from my main ArcGIS account to another trial account created for this (lasts only 21 days) -> I invite to see how simple and safe it is. https://youtu.be/8J6Be1l31nE My request is simple. I am looking for a gentle soul, with a licence, who would be kind enough to host my creation, so that it just remains there on the cloud, with a permanent link which is not going to get deleted, and for everyone to see if/when they desire. Thank you in advance for your help :) Julien -
hei pjduplooy, no , I just want to know how the user experience and if any, difficulties or even advantages using this software, just personal opinion on this product

Hi Lurker. I have tried the version you shared, but I prefer the Docker version to be honest. What help are you looking for? Or what do you want to know?
