    The Use of Gravimetry Satellites for Measuring Ice and Sea Level Change

    Lurker
    By Lurker,
    According to the National Snow and Ice Data Center in the United States, about 69% of freshwater supplies are stored in Earth’s ice sheets and glaciers. This means measuring water content in ice and glaciers is critical to understanding future changes to water supplies as well as sea level rise, where melting glaciers and ice sheets are the biggest contributing factor in this rise. Modern satellites now allow us to make more accurate mass measurements to large areas covered by ice, which al

    Thoughts about Mapbox 2.0 becoming Proprietary

    I am an avid user of the Mapbox JS library, and I use to map points of interest in some of our projects, like locations of survey targets for monitoring purposes. https://www.mapbox.com/mapbox-gljs   THe latest branch now includes improved support for 3D terrain, but I am still nt seeing support for negative elevations- i.e underground.  But with the news that Mapbox 2.0 is no longer open source, What are your thoughts about it? Certainly it has an imapct on the projects th

    There’s a new member of DJI’s Enterprise line of drones. It’s the Mavic 2 Enterprise Advanced, and it features a new 32X camera, a DJI-produced thermal sensor, and a Real-Time Kinematic module for centimeter-level accuracy. The new model comes a little more than two years after DJI released its Mavic 2 Enterprise, which proved a very popular drone with First Responders – ranging from lifeguards to law enforcement to Search and Rescue teams. It was that drone which heralded the modular desig

    Mapping Sea-Level Rise with Sentinel-6

    Lurker
    By Lurker,
    On November 21st, Sentinel-6 was launched by the European Space Agency (ESA) using a SpaceX Falcon 9 rocket. The satellite was developed in partnership with NASA and other agencies and was named after former NASA Earth Science Division Director Michael Freilich.[1]  The recent launch of Sentinel-6 Michael Freilich/Jason CS is the latest mission that will collect sea level measurements at more frequent intervals to monitor the effects of climate change on our oceans. With one of the biggest
