  3. 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 complete global coverage between -90° to 90° in latitude and -180° to 180° in longitude. The visualization simulates an incremental drop of 10 meters of the water’s level on Earth’s surface. As time progresses and the oceans drain, it becomes evident that underwater mountain ranges are bigger in size and trenches are deeper in comparison to those on dry land. While water drains quickly closer to continents, it drains slowly in our planet’s deepest trenches. These trenches start to become apparent below 5,000 meters, as the majority of the oceans have been drained of water. In the Atlantic Ocean, there are two trenches that stand out. In the southern hemisphere, the South Sandwich trench is located between South America and Antarctica, while in the northern hemisphere the Puerto Rico trench in the eastern Caribbean is its deepest part. The majority of the world’s deepest trenches though are located in the Pacific Ocean. In the southern hemisphere, the Peru-Chile or Atacama trench is located off the coast of Peru and the Tonga Trench in the south-west Pacific Ocean between New Zealand and Tonga. In the northern hemisphere, the Philippines Trench is located east of the Philippines, and in the northwest Pacific Ocean we can see a range of trenches starting from the north, such as the Kuril-Kamchatka, and moving to the south all the way to Mariana’s trench that drains last. It is worth recalling that the altitude values of ETOPO1 range between 8,333 meters (topography) and -10,833 meters (bathymetry). This range of altitude values reflects the limitations of the visualization, since Challenger Deep - the Earth’s deepest point located at Mariana's trench - has been measured to a maximum depth of 10,910 meters and Mount Everest the highest peak above mean sea level is at 8,848 meters. In this visualization the vertically exaggerated by 60x ETOPO1 relief model, utilizes a gray-brown divergent colormap to separate the bathymetry from topography. The bathymetry is mapped to brownish hues (tan/shallow to brown/deep) and the dry land to greys (dark gray/low to white/high). A natural consequence of this mapping is that areas of the highest altitude are mapped to whitish hues, as they are almost always covered in snow. Furthermore, in an effort to help viewer’s eyes detect surface details that would otherwise be unnoticeable, the topography and bathymetry have been rendered with ambient occlusion - a shadowing technique that in this particular visualization darkens features and regions that present changes in altitude, such as mountains, ocean crevices and trenches. download: https://svs.gsfc.nasa.gov/vis/a000000/a004800/a004823/OceanDrain_Colorbar_1920x1080_30fps.mp4 https://svs.gsfc.nasa.gov/vis/a000000/a004800/a004823/OceanDrain_1920x1080_30fps.mp4 source: https://svs.gsfc.nasa.gov/4823

  6. what that tools, using 9.3.1 is like using windows 2000 interface, even more not like XP experience nor Windows 7
  7. Earlier
  8. is there any chance to get the software? thanks
  9. These are some of the most common geographic misconceptions that are both surprising and surprisingly hard to correct. https://www.nationalgeographic.com/culture/2018/11/all-over-the-map-mental-mapping-misconceptions/

  11. I will still remain with the desktop for a long time. I stay until I extract the last drop. I still have version 9.3.1 running to be able to use some tools that don't work in version 10xxx
  12. I am back. Please re-activate my account. Thank you in advance.
  13. Please reinstate my account. Life was pre-empted by a family illness.
  14. The projection is realy with with AXIS["Y",EAST] and AXIS["X",NORTH]] and WFS reads it well while making GML, meaning Global Mapper reads only "regular" SRS axis order?
  15. Hi all, This is my first time using ENVI and I have applied atmospheric corrections. These are the steps I took: 1- Radiometric correction 2- FLAASH atmospheric correction 3- To eliminate the Negative values and make them between 0 and 1 in data values, I used this formula: (B1 le 0)*0+(B1 ge 10000)*1+(B1 gt 0 and B1 lt 10000)*float (b1)/10000 When I export the corrected later to TIFF, it will be in a 3 band composite but I need single bands to be exported as TIFF so I can use in Arcmap. So what I need is to use some bands of each image in Arcmap to make a composite eventually but I dont know how to export single bands when they are atmospherically corrected. I would appreciate any help on this! Could you please tell me in steps since Im very new to ENVI and know almost nothing about it!
  16. Hi people, When I connect to a WFS from GlobalMapper 21.1, a GML file with swapped coordinates is downloaded (northing-easting) and GlobalMapper reads these coordinates as they are easting-northing. Is there any workaround for this? ArcMap reads this WFS normally using Interoperability Extension without telling SRS axis order. GlobalMapper doesn't have any option to chose SRS axis order.
  17. Here some information about SkySat : Archive animation : theme constellation https://storage.googleapis.com/planet-ditl/day-in-the-life/index.html Technicals about syksat : https://space.skyrocket.de/doc_sdat/skysat-3.htm Orbits (click on the Track-it Button) https://www.n2yo.com/database/?q=skysat#results
  18. this response basically in every big software company, if you got error on windows for example, you will get pretty much same sh*t, ahahahaha I prefer search on 3rd party forum, like stakeoverflow or such....
  19. Tracing is better in ArcGIS Pro, but Cut Polygon cannot be done in ArcGIS Pro, only in ArcMap Dekstop
  20. what's really frustrating it's that esri still has his "standard response" every time I try to address an issue : - do you have the last version? (and of course in a big company you simply don't get the last last last patch at +1minute after the release > so this will be for them the solution nr. one. > and of course it will never change anything) .. then... The following question will be "can you send me a copy of your system configuration ?" (and of course they will find a way to say that your hardware it's "old" even if it does comply to all the requirements) - I'm pretty sure you have an installation issue.. please reinstall (so you have to get another problem with your IT department) VERY FRUSTRATING I'm in business since a while and every time those guys comes with the best solution for you I have an alarm bell going on.. * it will be a 64 bit solution (can you remember those bull****?), so better then arcmap and as always it doesnt make a little difference.. * it's 2D and 3D in one only software (but did they mention to you that you will need some extra licences? not to me). so basically.. I LOVE QGIS ! 😍😍😍
  21. A recently unclassified CIA drone program provides us with perspective on UAS development. Also, U.S. high-altitude surveillance capabilities are being tested, another record has been achieved, and an award for the U.S. Air Force space plane. 1960s CIA Bird-Drone Back when the U.S. was flying U2 spy planes over the Soviet Union and Gary Powers was on Russian TV after being shot down, the CIA got to thinking of another approach for gathering airborne intelligence. Project Aquiline was an early drone project aimed at making overflight much less conspicuous — because the drone was built to resemble a bird. With a two-stroke engine driving a pusher-propeller and an 8-foot wingspan, five prototypes were built and tested through 1967-68. The concept was to fly at lower altitudes than the U2, carrying equivalent camera and electronic surveillance equipment, but to be very difficult to observe from the ground. Although a two-stroke engine might have been somewhat noisier than a large bird, later phases of the program envisaged a miniature nuclear power source which presumably would have been much quieter with a relatively huge range. The project began in 1966, and prototypes began operational testing in 1968. The prototypes established a range of around 130 miles, took high-resolution images and successfully returned to the control site. However, with many stages of development still to go (the cost to complete was maybe too high), the project was canned in November 1971. Maybe this initial “bird” concept is where the name of today’s high-altitude, long-endurance Global Hawk drone originated — who knows? NASA High-Altitude Long-Endurance (HALE) UAVs But the U.S. government seems to have other objectives than just high-altitude reconnaissance. NASA has operated the Global Hawk drone for science missions for a number of years, alongside the U-2 and ER-2 high-altitude manned aircraft. Armstrong Flight Research Center operates two Global Hawks with support from Northrop Grumman out of Edwards Air Force Base. Global Hawk is flown with a pre-loaded mission profile at upwards of 60,000 feet, sometimes for as long as 24 hours and more than 8,000 miles. Nevertheless, the aircraft is monitored over both satellite and terrestrial links, with direct sensor payload access throughout. Global Hawk is powered by a Rolls-Royce AE3007H turbofan engine. It has a wingspan exceeding 116 feet, measures 44 feet from nose to tail, has a gross takeoff weight of 25,250 pounds and carries a 1,500-pound payload. But this aircraft is massive compared to another recent high-flying project that NASA funded through a Phase I and II Small Business Innovation Research/Technology Transfer (SBIR/SBTT) program. With the help of NASA’s Ames Research Center, Swift Engineering in San Clemente, California, completed a two-hour flight test on July 7 of its High-Altitude Long-Endurance (HALE) UAS, aiming to join the group of companies already in the high-altitude UAV club. The 72-foot wingspan, solar-powered HALE weighs <180 pounds, carries a 10-15-pound payload and is destined to fly at up to 70,000 feet for more than 30 days. This HALE aircraft is expected to complement existing NASA observation platforms and provide unique material alongside existing satellite data. Swift Engineering has been working with NASA Ames since 2016 on a proof-of-concept solar-powered UAS aimed at sustained flight for a month or more. Swift researched solar panels and high-power, multiple-cycle rechargeable battery technologies to develop a system that could survive harsh temperatures as well as the radiation encountered at high altitude. During the first of a series of flight tests at Spaceport America in New Mexico on July 7, operations at low altitude were completed to verify systems, aerodynamic control and power-system models. The July 7 flight was the first in a series to collect data and further validate the design. With NASA, Swift has developed a UAS to not only meet observation objectives, but also one that aligns with the Federal Aviation Administration’s view of HALE deployment and maintenance during extended flights. For the test flight, the vehicle carried a NASA FluidCam for science missions, with a focus on mapping coastal reef systems. NASA teams are exploring how aircraft such as Swift’s could perform as pseudo-satellites for air-quality monitoring, image coastal zones, map landslides and geologically active regions, and for real-time forestry and agricultural monitoring. The next step in the development is expected to be a Phase III series of scientific observations at high altitude for days and even weeks. Boeing X-37B Team Wins Collier Trophy The Air Force/Boeing X-37B autonomous space plane has won the Collier Trophy for best in U.S. aeronautics/astronautics performance and safety in 2019. The X-37B set a new 780-day on-orbit record and descended through the controlled U..S National Airspace System (NAS) to land at NASA’s Kennedy Space Center. Initially launched in 2010, the reliable, reusable and unmanned X-37B has provided space access and subsequent analysis for a large number of key experiments. The space plane has now broken its previous on-orbit record of 718 days and has orbited for 2,865 days and more than 1 billion miles in total. Originally designed for only 270 days in space, the X-37B has established endurance records in every one of its last five flights. Since 1911, recipients of the Collier Trophy have included Orville Wright, the Apollo 11 lunar landing team, the International Space Station team, the U.S. Navy F/A-18E/F Super Hornet team and the Boeing 787, 777 and 747 passenger aircraft teams. Intelligence Gathering News about the 1960 CIA drone developments, aimed at gathering unobserved photo reconnaissance intelligence, provide new perspective on NASA’s current-day use of high-altitude observation assets. These are the same types of assets that the U.S. currently uses for intelligence gathering, despite being recently intercepted by Russian jets off the coast of Alaska. It makes for interesting aspects of drone history, along with new aspects of (very) high-altitude unmanned capabilities. source: https://www.gpsworld.com/1960s-cia-drone-bird-project-a-predecessor-to-nasa-global-hawk/
  22. Current u-blox GNSS platforms — from u-blox M8 and beyond — support the recently completed BeiDou navigation satellite system modernizations, improving the availability of GNSS positioning services. The opening ceremony of the BeiDou-3 global navigation satellite system (GNSS) was held in Beijing on July 31, officially celebrating the expansion of coverage offered by the critical Chinese space infrastructure to a global user base. As a global supplier of GNSS positioning and wireless communication technologies, u-blox has been driving technological innovation and deeply involved in the Chinese market for many years. Tests conducted across China and Europe have shown that including the BeiDou system can improve the positioning accuracy of GNSS receivers when multiple navigation satellite systems are tracked concurrently. When signals are partially obstructed, positioning accuracy can be significantly improved by incorporating the BeiDou system. Data shows that in 2019, the overall output value of the Chinese satellite navigation and location service industry reached nearly 345 billion yuan, an increase of 14.4% over 2018, with the output value expected to exceed 400 billion yuan in 2020. Additional Services Provided by BeiDou The BeiDou system provides a suite of additional services, including satellite and ground-based augmentation services, precise single-point positioning, precise timing and global short message services, laying a solid foundation for BeiDou’s ubiquitous navigation and tracking applications. Applications of GNSS technology continue to diversify, leveraging the all-weather, all-time, tracking, navigation and timing services it offers. GNSS technology is penetrating deeper into traditional industrial verticals, such as agriculture, forestry, animal husbandry and fishery, power and energy, as well as in railway and air transportation, including their infrastructure construction and management. At the same time, GNSS technology has become an indispensable and “smart” factor in emerging application fields such as the internet of things and the “internet of vehicles,” as well as in innovative applications such as autonomous driving, automatic parking and automatic logistics, and is now commonplace in many industrial and consumer use cases. “U-blox has been closely following the modernization of the BeiDou navigation system and is ready to work with partners in various industries to promote the expansion of industry applications, expand emerging markets and jointly create a green industry ecosystem,” said Hamilton Chen, China country manager at u-blox. source: https://www.gpsworld.com/u-blox-technology-platforms-support-beidou-3/
  23. until they fix the performance issue, i dont see any advantages on ArcGIS Pro.... I still can use ArcGIS desktop for the daily task, no need to use fancy latest product
  24. The same questions people asked about 9.3x and 10x. IMHO ArcMap is unofficially dead, switch to Pro. It's Esri product so try to live with performance issues.
  25. 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 know where they are anymore. and I don't know for you, but it seems to me that "pro" is just an advertising program to convince even those who are not professionals to make maps, this even if they don't understand technically what they did.
  26. 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). Leveraging the near real-time information already contributed to Living Atlas by organizations such as NOAA, UN Environment Programme, and US Geological Survey, ArcGIS Living Atlas Indicators of the Planet draws upon authoritative sources for the latest updates on 18 topics, with more being developed. In addition to the summary statistics provided by the GeoCards, there are a series of maps and resources to better understand each issue and learn how to integrate timely data into decision making, along with stories on progress towards building a sustainable planet. ArcGIS Living Atlas Indicators of the Planet was developed using ArcGIS Experience Builder and is in its Beta release while additional capabilities are being implemented. This Experience Builder template can be customized for your own topics of interest. All of the underlying layers, maps, and apps are available from this Content Group. link: https://experience.arcgis.com/experience/003f05cc447b46dc8818640c38b69b83
