    Historic carbon dioxide decline could hold clues for future climate

    Lurker
    By Lurker,
    A new study led by researchers at The Australian National University (ANU) provides a clearer snapshot of conditions during the last ice age—when global ice sheets were at their peak—and could even lead to better models for future climate projections.   The study demonstrates a new way of recreating ocean conditions in the Atlantic during the Last Glacial Maximum (LGM)—around 20,000 years ago.   Lead author Dr. Jimin Yu says scientists have been trying to reconstruct ocean ci

    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

    Lurker
    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

    Lurker
    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

    Create Interactive Flow Maps

    Lurker
    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 . Ilya Boyandin has

    • The Association for Geographic Information (AGI) and the Government Geography Profession (GGP) have agreed to work together to combine their experience, expertise and outreach to further the impact of geospatial data and technology within the public sector. By working together, they will help grow the geospatial community, and will build on recent activities such as the AGI’s Skills Roundtable. “The UK is at the forefront of geospatial. Now more than ever, geographers are combining increasing quantities of geospatial information with advances in technology, such as AI and ML, to drive new insights on our place in the world,” commented David Wood, Head of the Government Geography Profession. “The profession is leading the way in government and the public sector, recognising and encouraging the use of geography and geographical sciences within and across government. By working with the AGI, we can increase awareness and therefore engagement with geographers across government and align our ambitions and activities with the wider geospatial community.” “Many of government’s greatest challenges are time and place related and therefore the data and technology that will help address and resolve them must also have location at its heart,” added Adam Burke, Past Chair of the Association for Geographic Information. “By partnering with GGP, we can help ensure the geospatial ecosystem continues to grow sustainably, both within government and beyond, and is utilised across diverse industry sectors and across multiple applications to impact positive outputs.” AGI is the UK’s geospatial membership organisation; leading, connecting and developing a community of members who use and benefit from geographic information. An independent and impartial organisation, the AGI works with members and the wider community alongside government policy makers, delivers professional development and provides a lead for best practice across the industry. Its mission is to nurture, create and support a thriving community, actively supporting a sustainable future, and it aims to achieve this by nurturing and connecting active GI communities, supporting career and skills development and providing thought leadership to inspire future generations. The GGP, established in 2018, is made up of around 1,500 professional geographers in roles across the public sector. The profession is working ‘to create and grow a high-profile, proud and effective geography profession that attracts fresh talent and has a secure place at the heart of decision making’. This is being achieved by creating the environment for geographers to have maximum impact, professionalising and progressing the use applications of geography and growing a diverse and inclusive community within government and the wider public sector. page: https://www.directionsmag.com/pressrelease/12860
    • As technology advances and AI becomes more sophisticated, there is a growing concern that GIS analysts might be replaced by AI algorithms. What are your thoughts on this potential shift? Will AI be able to match the expertise and intuition of human analysts in the field of Geographic Information Science?
    • Copernicus Open Access Hub is closing at the end of October 2023. Copernicus Sentinel data are now fully available in the Copernicus Data Space Ecosystem As previously announced in January the Copernicus Open Access Hub service continued its full operations until the end of June 2023, followed up by a gradual ramp-down phase until September 2023. The Copernicus Open Access Hub will be exceptionally extended for another month and will cease operations at the end of October 2023. To continue accessing Copernicus Sentinel data users will need to self-register on the new Copernicus Data Space Ecosystem. A guide for migration is available here. The new service offers access to a wide range of Earth observation data and services as well as new tools, GUI and APIs to help users explore and analyse satellite imagery. Discover more about the Copernicus Data Space Ecosystem at https://dataspace.copernicus.eu . A system of platforms to access EO data The Copernicus Data Space Ecosystem will be the main distribution platform for data from the EU Copernicus missions. Instant access to full and always up-to-date Earth observation data archives is supported by a new, more intuitive browser interface, the Copernicus Browser. Since 2015, the Copernicus Open Access Hub supports direct download of Sentinel satellite data for a wide range of operational applications by hundreds of thousands of users through the last decade. However, technology has moved on and the Copernicus Data Space Ecosystem was recently launched as a new system of platforms for accessing Sentinel data. As part of this process, the current access point will be gradually wound down from July 2023 and will no longer operate from end of October 2023. This post demonstrates how to migrate your workflow from accessing the data through the Copernicus Open Access Hub to using APIs via the Copernicus Data Space Ecosystem. In this post, we will show you how to: setup your credentials use OData to search the Catalog and download Sentinel-2 L2A Granules in .SAFE Format. search, discover and download gridded Sentinel-2 L2A data using the Process API Increase in data quality, quantity and accessibility With the glut of free and open data in recent years, the increases in revisit times and higher spatial and temporal resolutions, applications using earth observation data have blossomed. For example, before 2013, you would likely have used Landsat 8 data for land cover mapping with a revisit time of 16 days at 30m spatial resolution. In 2023 though, we now have access to Sentinel-2 with a revisit time of 3-5 days at 10m resolution enabling you not just to map land cover but monitor changes at higher spatial and temporal resolutions. Therefore, while it was feasible to download, process and analyse individual acquisitions in the past, this approach is no longer effective today and it makes more sense to process data in the cloud. This is where the new APIs provided by the Copernicus Data Space Ecosystem come in. official page: https://dataspace.copernicus.eu/
