Remote Sensing uncover widespread illegal fishing in Pacific Ocean
By Lurker,
Scofflaw ships hauled in more than 176,000 tons of Pacific flying squid in North Korean waters in 2017 and 2018.
A 55- to 60-meter lighting vessel of Chinese origin near North Korean waters. This vessel had its four arm-like structures deployed and flew both North Korean and Chinese flags.
Satellite imagery has dragged "dark" fishing fleets out into the light.
Orbital observations have revealed extensive illegal fishing of Pacific flying squid (Todarodes pacificus) i
Marine Species are Shifting Towards the Poles
By Lurker,
Global warming has caused a shift in species’ ideal habitats, prompting everything from mushrooms to trees, mammals to amphibians and other terrestrial species to seek out different ecological zones in which to thrive. New research is collecting data on marine species that are also experiencing climate related habitat migrations in greater numbers than scientists anticipated.
As species’ normal habitats are becoming warmer, habitat is lost due to human infrastructure, or habitats are becomi
UrsaNav installs eLoran testbed in South Korea
By Lurker,
South Korean is in the early stages of evaluating its eLoran system, but great results are expected based on the UrsaNav-supplied station in Incheon.
In August 2018, the Korea Research Institute of Ships and Oceans Engineering (KRISO) awarded UrsaNav, through its agent Dong Kang M-Tech, a contract to supply and install an eLoran transmitter testbed system in South Korea. UrsaNav is the exclusive, worldwide distributor of Nautel’s NL Series transmitters, provided eLoran transmitter tec
Garmin services and production go down after ransomware attack
By Lurker,
Smartwatch and wearables maker Garmin has shut down several of its services on July 23 to deal with a ransomware attack that has encrypted its internal network and some production systems.
The company is currently planning a multi-day maintenance window to deal with the attack's aftermath, which includes shutting down its official website, the Garmin Connect user data-syncing service, and even some production lines in Asia.
In messages shared on its website and Twitter, Garmin said the
Create Interactive Flow Maps
By Lurker,
Flow maps are cartographic visualizations to show the movement of objects, people, or other living things from one location to another. Lines, usually symbolized with an arrow to indicate the direction. Color coding or line width can also then be used to indicate the volume of objects that are moving from one location to another. Airline traffic, animal migration, commuters, and import/exports are all common types of geographic data that are typically shown on a flow map .

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 -
Hello, As part of a project requested by the University where I study, I was asked to detect the temporal progression of a cork oak forest (Maamora in Morocco). To do this I turned to the NDVI index but I do not know the values of a pixel of cork oak forest concerning this index. So, I turn to you to give me an interval for the NDVI of the cork oak or why not another indicator that would better detect this kind of forest. -

I don't have experience with Geoserver, but I think you may want to try OAuth to create user specific credential. The users who use to login usually invokes the same unique url from the system, which is common for many websites. The user then may save that credential in the browser cookie if they like. Using that same unique credential with the WFS link might be an overkill, since you can already track and limit the resource usage of that WFS link. This is a kind of question suitable for gis.stakexchange though. -
Dear Experts.. Anyone has experience on generating WFS links based custom key authentication on a particular users with their keys using ARCGIS tools..instead of username & password.. Thank You -
