  1. geemap is a Python package for interactive mapping with Google Earth Engine (GEE), which is a cloud computing platform with a multi-petabyte catalog of satellite imagery and geospatial datasets. During the past few years, GEE has become very popular in the geospatial community and it has empowered numerous environmental applications at local, regional, and global scales. GEE provides both JavaScript and Python APIs for making computational requests to the Earth Engine servers. Compared with the comprehensive documentation and interactive IDE (i.e., GEE JavaScript Code Editor) of the GEE JavaSc

  3. It was just announced that June was the 3rd hottest on record, Johns Hopkins put the number of COVID-19 cases at 13-million, and over 300,000 sq km of protected areas were created last month. These are all indicators of the planet’s vitality, but traditionally you’d need to bookmark three different websites to keep track of these and other metrics. In partnership with Microsoft, National Geographic, and the United Nations Sustainable Development Solutions Network, Esri is gathering these and other topics into the ArcGIS Living Atlas Indicators of the Planet (Beta).

Described in this video, this set was created for 3 reasons: (1) to provide a set of analytical lessons that can be immediately used, (2) to update the original 10 lessons created by my colleague Jill Clark and I to provide a practical component to our Esri Press book The GIS Guide to Public Domain Data, and (3) to demonstrate how ArcGIS Desktop (ArcMap) lessons can be converted to Pro and to reflect

  9. 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 .

  10. NGS has developed a new beta tool for obtaining geodetic information about a passive mark in their database. This column will highlight some features (available as of Oct. 5, 2020) that may be of interest to GNSS users. It provides all of the information about a station in a more user-friendly format. The box titled “Passive Mark Lookup Tool” is an example of the webtool. The tool provides a lot of information so I have separated the output of the tool into several boxes titled “Passive Mark Lookup Tool — A through D.” I will highlight several attributes that I believe will be very useful

  11. Earth is known as the “Blue Planet” due to the vast bodies of water that cover its surface. With an over 70% of our planet’s surface covered by water, ocean depths offer basins with an abundance of features, such as underwater plateaus, valleys, mountains and trenches. The average depth of the oceans and seas surrounding the continents is around 3,500 meters and parts deeper than 200 meters are called "deep sea". This visualization reveals Earth’s rich bathymetry, by featuring the ETOPO1 1-Arc Minute Global Relief Model. ETOPO1 integrates land topography and ocean bathymetry and provides

  12. hello everyone, I'm a long time user of arcmap and already two years ago on my computer I installed arcgis pro... now I don't know for you but I'm postponing for years the real switch between versions and I'm still on arcmap... this because it seems to me that even if the expectations were very high, arcgis pro still doesn't seem to have that much declaimed performance. In particular, I'm concerned about the fact that for every little thing, it starts a geoprocessing that lasts between seconds and minutes, then for each function is a maze of menus and submenus where at the end I don't

  16. A joint NASA-USGS initiative has created the first worldwide map of the causes of change in mangrove habitats between 2000 and 2016. Mangrove trees can be found growing in the salty mud along the Earth’s tropical and subtropical coastlines. Mangroves are vital to aquatic ecosystems due to their ability to prevent soil erosion and store carbon. Mangroves also provide critical habitat to multiple marine species such as algae, barnacles, oysters, sponges, shrimp, crabs, and lobsters. Mangroves are threatened by both human and natural causes. Human activities in the form of farming and aquacu

National Snow and Ice Data Center (NSIDC) scientists and colleagues predicted via a 2017 paper in The Cryosphere that the ice caps would melt out completely within the next five years, and recent images from NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) have confirmed that this prediction was accurate.

The study crowdsourced GPS monitoring data from antennae across western Europe to track subtle movements in the Earth’s surface, thought to be caused by a rising subsurface mantle plume. The Eifel region lies roughly between the cities of Aachen, Trier and Koblenz, in west-central Germany. It is home to many ancient volcanic features, including the circular lakes known as maars. Maars are the remnants of violent volcanic eruptions, such as the one that created Laac

  21. Stop me if you’ve heard this before. DJI has introduced its latest enterprise powerhouse drone, the DJI Matrice 300 RTK. We learned a lot about the drone earlier this week due to a few huge leaks of specs, features, photos, and videos. But it’s worth looking at the drone again now that it’s official – and an incredible intro video. Also called the M300 RTK, this drone is an upgrade in every way over its predecessor, the M200 V2. That includes a very long flight time of 55 minutes, six-direction obstacle avoidance, and a doubled (6 pound) payload capability. That allows it to carry a range

  22. @intertronic, thanks for your input. I found a solution that suite my case better due to the fact that we are using both version of QGIS and also because I was looking for interoperability. Therefore I have decided to use QSphere.

  23. DRONE MAKER DJI announced an update to its popular Mavic Air quadcopter today. The Mavic Air 2 will cost $799 when it ships to US buyers in late May. That's the same price as the previous Mavic Air model, so the drone stays as DJI's mid-range option between its more capable Mavic 2 and its smaller, cheaper Mavic Mini. The Mavic Air 2 is still plenty small, but the new version has put on some weight. DJI says that testing and consumer surveys suggested that most people don't mind lugging a few extra grams in exchange for a considerable upgrade in flight time and, presumably, better handlin

After the Dead Sea, the Sea of Galilee is the world’s second-lowest lake in the world. The lake measures 21 kilometers (13 miles) north-south, and it is only 43 meters (141 feet) deep. Most of the inflow of water to the Sea of Galilee arrives via the Jordan River from the north, although some underground springs drain into the lake.

  38. Researchers have developed an algorithm that can distinguish between volcanic and non–volcanic clouds using high-resolution satellite imagery. Called the Cloud Growth Anomaly (CGA) technique, the algorithm uses geostationary satellite data to detect fast growing vertical clouds caused by volcanic output. Volcanic ash produced by eruptions are a major threat to airplanes. In 2011, for example, Grímsvötn erupted, closing Iceland’s air space. Volcanic ash can cause significant damage to airplanes including in-flight engine failure. Researchers noted that “volcanic clouds produced by explosiv

  41. Changes in ocean circulation may have caused a shift in Atlantic Ocean ecosystems not seen for the past 10,000 years, new analysis of deep-sea fossils has revealed. This is the striking finding of a new study led by a research group I am part of at UCL, funded by the ATLAS project and published in the journal Geophysical Research Letters. The shift has likely already led to political tensions as fish migrate to colder waters. The climate has been quite stable over the 12,000 years or so since the end of the last Ice Age, a period known as the Holocene. It is thought that this stabili
