  1. Planet is set to launch three more new SkySats (SkySats 19-21) into Low Earth Orbit on August 18th (date subject to change), rounding out the fleet of SkySats already in operations and joining SkySats 16-18 that successfully launched aboard the SpaceX Falcon 9 in June. Planet SkySats 1-15 operate in Sun Synchronous Orbits, a specific type of Low Earth Orbit that results in the Earth’s surface always being illuminated by the Sun at the same angle when the satellite is capturing imagery. Half of the SkySats currently pass overhead in a morning crossing plane, while the other half moves in an afternoon crossing plane, so together they provide the twice-daily coverage of anywhere on Earth. Both sets of new SkySats, 16-18 and 19-21, will operate in a “mid-inclination” orbit of 53 degrees that complements the sun synchronous fleet, and will offer more targeted coverage and imaging capacity in the latitude bands between +53 degrees and -53 degrees where the majority of human activity occurs. By taking advantage of SpaceX’s rideshare program, we were able to get these satellites launched much faster compared to a dedicated launch. In addition, by splitting the payload across two launches, we’re able to phase the mid-inclination SkySats into their respective planes much faster as well, all of which results in Planet’s customers benefiting from these enhanced products much sooner than any other provider can offer. SkySats 19-21 will be launched aboard SpaceX’s Falcon 9, a two-stage reusable rocket that has successfully flown satellites and cargo over 80 times to orbit. They will do so as rideshare payloads on SpaceX’s Starlink satellites, and will launch from the Cape Canaveral Air Force Base in Florida. The rapid launch of SkySats 16-21, as well as the development of our enhanced 50 cm imagery, are just a few examples of how Planet continues to push the envelope to provide industry-leading geospatial offerings that continuously improve over time. source: https://www.planet.com/pulse/skysats-19-21-to-launch-on-spacex-falcon-9-rideshare-mission/
  2. NASA’s ARIA team, in collaboration with the Earth Observatory of Singapore, used satellite data to map the extent of likely damage following a massive explosion in Beirut. Dark red pixels represent the most severe damage. Areas in orange are moderately damaged, and areas in yellow are likely to have sustained somewhat less damage. Each colored pixel represents an area of 30 meters (33 yards). The map contains modified Copernicus Sentinel data processed by ESA (European Space Agency) and analyzed by ARIA team scientists at NASA’s Jet Propulsion Laboratory, Caltech, and Earth Observatory of Singapore. Based in Pasadena, California, Caltech manages JPL for NASA. Scientists are using satellite data to map ground surface changes in the aftermath of the recent explosion. NASA’s Advanced Rapid Imaging and Analysis (ARIA) team, in collaboration with the Earth Observatory of Singapore, used satellite-derived synthetic aperture radar data to map the likely extent of damage from a massive August 4 explosion in Beirut. Synthetic aperture radar data from space shows ground surface changes from before and after a major event like an earthquake. In this case, it is being used to show the devastating result of an explosion. On the map, dark red pixels — like those present at and around the Port of Beirut — represent the most severe damage. Areas in orange are moderately damaged and areas in yellow are likely to have sustained somewhat less damage. Each colored pixel represents an area of 30 meters (33 yards). Maps like this one can help identify badly damaged areas where people may need assistance. The explosion occurred near the city’s port. It claimed more than 150 lives and is estimated to have caused billions of dollars’ worth of damage.

China successfully launched a new optical remote-sensing satellite from the Jiuquan Satellite Launch Center at 12:01 p.m. Thursday (Beijing Time). (Photo by Wang Jiangbo/Xinhua) JIUQUAN, Aug. 6 (Xinhua) -- China successfully launched a new optical remote-sensing satellite from the Jiuquan Satellite Launch Center in northwest China at 12:01 p.m. Thursday (Beijing Time). The satellite, Gaofen-9 04, was sent into orbit by a Long March-2D carrier rocket. It has a resolution up to the sub-meter level. The satellite will be mainly used for land surveys, city planning, land right confirmation, road network design, crop yield estimation and disaster prevention and mitigation. It will also provide information for the development of the Belt and Road Initiative. The same carrier rocket also sent the Gravity & Atmosphere Scientific Satellite (Q-SAT) into space. The Q-SAT satellite, developed by Tsinghua University, will help with the satellite system design approach and orbital atmospheric density measurement, among others. Thursday's launch was the 342nd mission of the Long March rocket series. source: http://www.xinhuanet.com/english/2020-08/06/c_139269788.htm
  5. The St. Patrick Bay ice caps on the Hazen Plateau of northeastern Ellesmere Island in Nunavut, Canada, have disappeared, according to NASA satellite imagery. 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. Mark Serreze, director of NSIDC, Distinguished Professor of Geography at the University of Colorado Boulder, and lead author on the paper, first set foot on the St. Patrick Bay ice caps in 1982 as a young graduate student. He visited the ice caps with his advisor, Ray Bradley, of the University of Massachusetts. "When I first visited those ice caps, they seemed like such a permanent fixture of the landscape," said Serreze. "To watch them die in less than 40 years just blows me away." In 2017, scientists compared ASTER satellite data from July 2015 to vertical aerial photographs taken in August of 1959. They found that between 1959 and 2015, the ice caps had been reduced to only five percent of their former area, and shrank noticeably between 2014 and 2015 in response to the especially warm summer in 2015. The ice caps are absent from ASTER images taken on July 14, 2020. The St. Patrick Bay ice caps were one-half of a group of small ice caps on the Hazen Plateau, which formed and likely attained their maximum extents during the Little Ice Age, perhaps several centuries ago. The Murray and Simmons ice caps, which make up the second half of the Hazen Plateau ice caps, are located at a higher elevation and are therefore faring better, though scientists predict that their demise is imminent as well. "We've long known that as climate change takes hold, the effects would be especially pronounced in the Arctic," said Serreze. "But the death of those two little caps that I once knew so well has made climate change very personal. All that's left are some photographs and a lot of memories." source: https://phys.org/news/2020-07-canadian-ice-caps-scientific.html
  6. Despite the controversy related to China-India border, this articles show us the importance of Remote Sensing as a strategic tools on Politic and Military The recent deaths of at least 20 soldiers along the contested border at Ladakh between India and China represents the largest loss of life from a skirmish between the two countries since the clashes in 1967 that left hundreds dead. It also highlights the tensions that have been building along the Line of Actual Control since early May. Using this satellite imagery, I will try to illustrate the approximate reality on the ground. My analysis disproves some of the more extreme claims that have been made about the incident, such as that thousands of Chinese soldiers have crossed the LAC and encamped in Indian-controlled territory. The satellite pictures also highlight the obvious threats to a peaceful status quo that exist along the western sector of India’s border with China. The analysis includes evidence that strongly suggests People’s Liberation Army forces have been regularly crossing into Indian territory temporarily on routine patrol routes. The details of this week’s clashes are still murky. But based on recent satellite imagery and media reporting, it appears the bulk of casualties were the result of soldiers falling during hand-to-hand fighting along a steep ridgeline that marks the LAC. The small area that is at the heart of this dispute appears to straddle the LAC and likely houses less than 50 Chinese troops. Neither Beijing nor Delhi considers the loosely demarcated line that separates the two countries in Ladakh to be an authoritative border. It approximates areas of territorial control established at the end of the 1962 Sino-Indian War when China withdrew from much of its captured territory on the Himalayan plateau. The border standoff at Ladakh has become a politically charged issue in India. The Indian government has revealed few details about the situation over the past few weeks. Former Indian Army officers, however, have been providing information to journalists and the media have been consistently painting a picture of a substantial conflict, often involving claims of the incursion of 10,000 PLA troops into undisputed Indian territory. The reality is less dramatic, but does represent a significant change to the status quo along the India–China border that threatens to escalate. By analysing satellite imagery from late May and early June it’s possible to make informed judgements about the positions of forces at multiple hotspots. Along the India–China border there are three key areas that produce the majority of tension between the two countries: Arunachal Pradesh; Sikkim and nearby Doklam (the site of a major skirmish in 2017 that saw Indian troops enter Bhutanese territory to prevent the completion of a strategic road being built by China); and Ladakh. The build-up of troops and military positions in recent months has been mostly in the Ladakh sector. Developments have occurred in three strategic areas along the LAC: the Galwan River Valley, where this week’s deadly clashes occurred; Hot Springs, where satellite evidence suggests that Chinese forces have regularly entered Indian territory; and the Pangong Tso. complete story : https://www.aspistrategist.org.au/satellite-images-show-positions-surrounding-deadly-china-india-clash/ https://www.indiatoday.in/india/story/latest-satellite-images-show-situation-far-from-normal-at-ladakh-s-pangong-tso-1706373-2020-07-31
  7. This is without a doubt the most anticipated feature of the year for CarPlay users, as Google Maps can now replace Apple Maps on the multi-view screen. Apple originally locked the maps card on the CarPlay dashboard to Apple Maps, which means that users weren’t allowed to configure any other application to display real-time information in this panel. It goes without saying this was quite an issue for many users, especially as Google Maps and the Google-owned Waze are extremely popular choices among CarPlay users. The release of iOS 13.4 in April brought massive changes in this regard, as the maps card was unlocked for third parties, essentially allowing any developer of such an app to add support for the dashboard and thus be able to replace Apple Maps. Google, however, has never been in a rush to make the whole thing happen, so here we are in early August finally getting support for Google Maps on the dashboard. What you need to know, however, is that the feature is only available for testers who are part of the beta program, but chances are that support for the multi-view screen on CarPlay will be included in one of the next Google Maps updates rolling out this month for production devices. In the meantime, Waze is yet to get this feature, as not even the beta builds of the app come with it. However, I’m guessing it’s all now just a matter of time until Waze is being updated with dashboard support on CarPlay, and I’m expecting Google to make this happen in its traffic navigation app rather sooner than later. On a side note, Google has also released a new Google Maps update for the stable channel on iOS, bringing the app to version 5.49. This one, however, includes only fixes and improvements, so no dashboard support for now on production devices. source: https://www.autoevolution.com/news/google-releases-the-most-anticipated-google-maps-carplay-feature-for-testers-146802.html#
  8. Scientists have discovered new evidence for active volcanism next door to some of the most densely populated areas of Europe. 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 Laacher See, the largest lake in the area. The explosion that created the lake is thought to have occurred around 13,000 years ago. The mantle plume that fed this ancient activity is thought to still be present, extending up to 400 kilometers (km) into the earth. However, whether or not it is still active is unknown. “Most scientists had assumed that volcanic activity in the Eifel was a thing of the past,” said Corné Kreemer, lead author of the new study. “But connecting the dots, it seems clear that something is brewing underneath the heart of northwest Europe.” In the new study, the team — based at the University of Nevada, Reno and the University of California, Los Angeles — used data from thousands of commercial and state-owned GPS stations all over western Europe. The research revealed that the region’s land surface is moving upward and outward over a large area centered on the Eifel, and including Luxembourg, eastern Belgium and the southernmost province of the Netherlands, Limburg. “The Eifel area is the only region in the study where the ground motion appeared significantly greater than expected,” said Kreemer. “The results indicate that a rising plume could explain the observed patterns and rate of ground movement.” The new results complement those of a previous study in Geophysical Journal International that found seismic evidence of magma moving underneath the Laacher See. Both studies point towards the Eifel being an active volcanic system. The implication of this study is that there may not only be an increased volcanic risk, but also a long-term seismic risk in this part of Europe. The researchers urge caution, however. “This does not mean that an explosion or earthquake is imminent, or even possible again in this area. We and other scientists plan to continue monitoring the area using a variety of geophysical and geochemical techniques, to better understand and quantify any potential risks.” source: https://doi.org/10.1093/gji/ggaa227
  9. 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 circulation for this time period for decades, because of the clues it offers about past CO2 levels and changes in climate. "The LGM was a time of much lower CO2 levels, lower global temperature and lower sea levels," Dr. Yu said. The researchers say old ocean models cannot explain recently published data on the LGM, meaning a change in thinking was needed. Using marine sediments to reconstruct deep-water carbonate ion—which traces reflecting seawater acidity—the group generated a first-of-its kind map showing water conditions for the last glacial Atlantic. This map reveals a new glacial deep Atlantic circulation model. "We found that carbon-rich Pacific Deep Water extended northward up to about 20° S in the South Atlantic at three to four kilometers depth during the Last Glacial Maximum," Dr. Yu said. "This may have contributed critically to the decline in atmospheric CO2, thereby helping to initiate the glacial maximum." According to Dr. Yu, ocean circulation is a key regulator of climate, storing and transporting heat, carbon and nutrients. "This study suggests as waters shifted during the LGM, carbon was stored in the deep ocean, lowering atmospheric CO2 levels," Dr. Yu said. This information could also help improve or test the performance of various climate models. "If a model is able to reproduce the data—a method known as hindcasting or backtesting—it might give us confidence in the model's ability to map out future climate conditions," Dr. Yu said. source:
  10. 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) in the Pacific Ocean around Russia, Japan and North and South Korea in 2017 and 2018, a new study reports. In fact, "extensive" may not be a strong enough word. More than 900 vessels of Chinese origin probably violated United Nations sanctions by fishing in North Korean waters in 2017, and another 700 did the same in 2018, the study found. Watch the video HERE These scofflaw ships likely hauled in more than 176,000 tons (160,000 metric tons) of Pacific flying squid over those two years, a catch worth about US $440 million, study team members said. That's nearly equivalent to the combined T. pacificus catch of Japan and South Korea over the same span. "The scale of the fleet involved in this illegal fishing is about one-third the size of China's entire distant-water fishing fleet," said study co-lead author Jaeyoon Park, a senior data scientist at Global Fishing Watch, an international nonprofit organization dedicated to increasing ocean sustainability via greater transparency. "It is the largest known case of illegal fishing perpetrated by vessels originating from one country operating in another nation's waters," Park said in a statement. Park and his colleagues tracked fishing activity in the Pacific around the Koreas, Japan and Russia, a big patch of poorly monitored ocean. Many of the vessels plying these waters are dark, meaning they don't publicly broadcast their positions and don't show up in monitoring databases. So the researchers got a bird's-eye view, studying the region using four different types of satellite information. For example, the researchers pored through Automatic Identification System (AIS) data, which is designed to help ships keep tabs on traffic in their area and avoid collisions. AIS signals stream continuously from transponders on ships, and these signals are often detected via satellite. But many ships don't beam out AIS signals, and the ones operating illegally are very unlikely to do so. The team also looked at optical imagery gathered by Earth-observing satellites operated by San Francisco-based company Planet. The researchers analyzed wide-field photos captured by Planet's shoebox-sized Dove cubesats, as well as targeted imagery from larger, sharper-eyed SkySats. several vessels (only two shown). White lines connect their most recent AIS position to the estimated position during the time of the satellite image, based on extrapolating the vessel’s speed and course. In white is the 9-digit Maritime Mobile Service Identity (MMSI) of each vessel. (Image credit: © Planet) In addition, Park and his colleagues scrutinized data from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP, a satellite operated jointly by NASA and the U.S. National Oceanic and Atmospheric Administration. VIIRS can spot brightly lit ships at night, which makes it well suited to hunt squid boats; these vessels usually operate after dark, drawing squid up from the depths with huge banks of very bright lights. The researchers also used synthetic-aperture radar (SAR) imagery to hunt for large metal vessels in the region. The team used SAR data from several different satellites: the European Space Agency's Sentinel-1, the Japanese Space Exploration Agency's PALSAR-2, and RADARSAT-2, which is operated by the company Kongsberg Satellite Services. Combining all of this information allowed the team to determine the extent of illegal fishing in the area — something that had never been done on this scale, team members said. "These novel insights are now possible thanks to advances in machine learning and the rapidly growing volume of high-resolution, high-frequency imagery that was unavailable even a couple of years ago," co-author David Kroodsma, Global Fishing Watch research and innovation director, said in the same statement. "We've shown we can track industrial fishing vessels that are not broadcasting their locations." The new study, which was published online today (July 22) in the journal Science Advances, suggests that the illegal vessels pose a significant threat to the management of the T. pacificus fishery. That fishery is extremely valuable — T. pacificus is the top seafood by production value in South Korea, and one of the top five seafoods eaten in Japan — and it's on an unsustainable trajectory. Since 2003, reported catches of T. pacificus have dropped by 80% and 82% "Global fisheries have long been dominated by a culture of unnecessary confidentiality and concealment. Achieving a comprehensive view of fishing activity is an important step toward truly sustainable and cooperative fisheries management, and satellite monitoring is a key part of the solution," co-author Quentin Hanich, an associate professor at the Australian National Center for Ocean Resources and Security at the University of Wollongong, said in the same statement. "This analysis represents the beginning of a new era in ocean management and transparency," Hanich added. The team also determined that about 3,000 North Korean ships fished illegally in Russian waters in 2018, likely pushed so far afield by competition with the illegal Chinese vessels in their own backyard. Most of the North Korean boats are small and made of wood, and therefore not designed for such long open-ocean voyages. Indeed, hundreds of North Korean fishing vessels have washed up on Japanese and Russian shores in recent years, study team members said. "The consequences of this shifting effort for North Korean small-scale fishers are profound, and represent an alarming and potentially growing human rights concern," study co-author Katherine Seto, an assistant professor of environmental studies at the University of California, Santa Cruz, said in the same statement. source: https://www.space.com/illegal-fishing-squid-satellite-imagery.html
  11. 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 becoming hostile in other ways, species of plants, animals, bacteria, and fungi are looking for other locations nearby that provide an environment in which they can thrive. Species often look for cooler climates, which means heading toward Earth’s poles, up mountains, or into other areas that provide shelter from the temperature fluctuations brought on by global warming. Tracking Marine Habitat Shifts A recent study published in the journal Nature Ecology and Evolution compiled data from 258 peer-reviewed studies that analyzed over 12,000 species and over 30,000 habitat shifts in different plants, animals, fungi, and bacteria. The study created BioShifts, a comprehensive analysis of habitat shifts that have affected marine and terrestrial animals because of global warming and climate changes. The researchers found that marine species were shifting their habitats toward Earth’s poles on an average of six kilometers (3.7 miles) per year. While this doesn’t sound like a dramatically quick shift, terrestrial species are moving poleward on average of 1.8 meters per year (or about 5.9 feet). Graph visualizing the latitude shifts of species collected from 258 peer-reviewed studies on the responses of species to climate change. Graph: Lenoir et al., 2020. There are a few reasons why marine species feel the effects of climate change more acutely than those on land and are able to move faster in reaction to temperature changes. Air conducts heat 25 times less effectively than water, which means the ocean is heating up a lot faster than the land is. Many marine species are cold-blooded and don’t have the regulatory mechanisms that many terrestrial species have to handle fluctuations in their internal temperatures. Additionally, they are able to shift towards more sufficient habitats because there aren’t cities, roads, and other human infrastructure blocking the way. Barriers to Terrestrial Habitat Shifts On land, habitat loss and climate change can force species to break up in different directions. While their internal mechanisms are prompting them to head to cooler places, they may be blocked by human development and pushed further away from their ideal habitable zones. source: https://www.geographyrealm.com/marine-species-are-shifting-towards-the-poles/

  13. 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 technology, as well as timing, control and differential reference station equipment for the testbed. The contract represented the first phase in a broader program to upgrade Korea’s Loran-C stations to be the foundation of a sovereign Enhanced Loran (eLoran) positioning, navigation and timing (PNT) service. “The Republic of Korea recognizes the challenges associated with relying solely on space-based signals, the relative ease with which those signals can be jammed or spoofed, and the necessity to provide trusted time and trusted position to its citizens and critical national infrastructure,” said Charles Schue, CEO of UrsaNav. Many critical infrastructure sectors rely on accurate time and position, including maritime, aviation, electrical distribution, telecommunications, finance/banking, and digital broadcast. A complementary PNT (CPNT) service provides continuity of operations through alternative and diverse timing and positioning information. CPNT is a vital element in ensuring national security and assuring trusted time and position. KRISO, in conjunction with the Korea Ministry of Oceans and Fisheries (MOF), is developing an Initial Operating Capability eLoran system to provide complementary PNT services as a part of its Electronic Navigation (E-Navigation) mission. KRISO selected UrsaNav Inc. as its prime eLoran systems contractor through a competitive tender offer. UrsaNav provided, installed and tested an eLoran transmission system at a temporary location near Incheon, South Korea, in November 2019. The company also provided ancillary equipment for Additional Secondary Factor (ASF) map measurements and map-generation software, as well as differential reference station equipment to KRISO. Because of land size restrictions at the temporary site at Incheon, the eLoran transmission system was paired to a small footprint 35-meter top-loaded monopole antenna. In addition to the equipment provided by UrsaNav, MOF separately contracted a local Korean firm to provide an interim GPS receiver set to synchronize the existing Loran-C sites at Pohang and Kwangju to UTC. KRISO is in the early stages of measuring the performance of the Korea eLoran system, but results are expected to show better than 20-meter navigational accuracy within 30 kilometers of the differential reference station at the port of Pyeongtaek. Once the eLoran performance has been proven, MOF plans to move the Incheon eLoran equipment to a permanent site, potentially on the island of Socheongdo, and pair it with a larger “Tee” antenna to increase the output power and coverage area of the system. MOF also plans to upgrade the existing UTC synchronized Loran-C transmission sites at Pohang and Kwangju with new eLoran transmission equipment systems. The ministry will potentially add two additional transmission sites to provide complete coverage of the land and territorial waters of South Korea. source: https://www.gpsworld.com/ursanav-installs-eloran-testbed-in-south-korea/
  14. 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 same outage also impacted its call centers, leaving the company in the situation of being unable to answer calls, emails, and online chats sent by users. The incident didn't go unnoticed and has caused lots of headaches for the company's customers, most of which rely on the Garmin Connect service to sync data about runs and bike rides to Garmin's servers, all of which went down on Thursday. since the incident took root at around 03:00am UTC, several Garmin employees took to social media to share details about the attack, all calling it a ransomware attack. Some Garmin employees even went as far as to attribute the incident to a new strain of ransomware that appeared earlier this year, called WastedLocker -- information that ZDNet has not been able to verify based on employee claims. However, the incident appears to be much larger and more devastating than Garmin indicated via its initial statement. iThome, a Taiwanese tech news dedicated to IT topics and smart devices, shared an internal memo that Garmin's IT staff sent its Taiwan factories, announcing two days of maintenance mode planned for Friday and Saturday, July 24 and July 25. While the memo didn't specifically blame the impromptu maintenance mode on a ransomware attack, sources told the Taiwanese news site the incident was caused by a "virus." In today's cyber-security landscape, only ransomware attacks have the destructive effect to cause companies to shut down production lines, online services, websites, email servers, and call centers in a matter of hours and enter maintenance mode. In the meantime, Garmin users have been sharing tips online on how to save run and bike ride info to Garmin partner services, such as Strava, to avoid losing their workout information until Garmin solves its current outage. source: https://www.zdnet.com/article/garmin-services-and-production-go-down-after-ransomware-attack/
  15. 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 developed an easy-to-use online tool called Flowmap.blue that takes location data stored in Google Sheets to visualize interactive flow maps. Built using flowmap.gl, deck.gl, mapbox, d3, blueprint, CARTOColors, Flowmap.blue is a browser-based tool that lets users visualize and animate the movement of geographic data between locations. User can quickly set up their own custom flow maps by copying the template spreadsheet and adding in their own location data. The site also hosts plenty of examples that showcase how flowmap.blue was used to map out commuter trips, bicycle rides and sharing trips, human migration, animal migration patterns, and modeling a sewer system. site: https://flowmap.blue/
