Rivers melt Arctic ice, warming air and ocean
By Lurker,
A new study shows that increased heat from Arctic rivers is melting sea ice in the Arctic Ocean and warming the atmosphere.
The study published this week in Science Advances was led by the Japan Agency for Marine-Earth Science and Technology, with contributing authors in the United States, United Arab Emirates, Finland and Canada.
According to the research, major Arctic rivers contribute significantly more heat to the Arctic Ocean than they did in 1980. River heat is responsible
Resilient PNT critical to maritime advancement
By Lurker,
The International Maritime Organization (IMO) has issued a resolution for maritime cyber-risk management, effective January 2021. IMO Resolution MSC.428(98) affirms that maritime operators need to address cyber threats that risk the integrity and availability of technology systems.
GPS/GNSS signal jamming and spoofing expose the vulnerabilities of PNT-reliant systems. The single point of failure in the signals used to synchronize military operations or determine a vessel’s location leaves m
Will ArcGIS run inside the new M1 Mac ?
By rahmansunbeam,
We already know that the new Macs with M1 chip can run both Intel and ARM apps made for macOS and iOS, but Mac users who rely on Windows for some specific software have lost Boot Camp support. However, CodeWeavers announced that CrossOver 20 now works on Apple Silicon Macs, which means that the new M1 Macs can run Windows software right on macOS.
If you’re unfamiliar with CrossOver, it’s a platform based on the open-source Wine project that can run the Windows environment on macOS and Linux

DEM filtering Algorithm
By stuart1974,
Hi,
I have a sample DEM that has been generalized and filtered but keeping the sharpness of features. I have tried all filters i know but i couldn't replicate it. I would like to see if someone knows how to do it.
Below are the links for the original and processed DEM:
Processed: http://www.mediafire.com/file/1rv6nq3d3fwi6tp/filtered.jpg/file
Original: http://www.mediafire.com/file/rn1jkbd06uwhkr4/original.jpg/file
Thanks in advance
Stuart

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 -

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?
