  2. At this time, USGS Landsat 9 Collection 2 Level-1 and Level-2 data will be made available for download from EarthExplorer, Machine to Machine (M2M), and LandsatLook. Initially, USGS will provide only full-bundle downloads. USGS will provide single band downloads and browse images, and Landsat 9 Collection 2 U.S. Analysis Ready Data shortly thereafter. Commercial cloud data distribution will take 3-5 days to reach full capacity. The recently deployed Landsat 9 satellite passed its post-launch assessment review and is now operational. This milestone marks the beginning of the satellite’s mission to extend Landsat's unparalleled, 50-year record of imaging Earth’s land surfaces, surface waters, and coastal regions from space. Landsat 9 launched September 27, 2021, from Vandenberg Space Force Base in California. The satellite carries two science instruments, the Operational Land Imager 2 (OLI-2) and the Thermal Infrared Sensor 2 (TIRS-2). The OLI–2 captures observations of the Earth’s surface in visible, near-infrared, and shortwave-infrared bands, and TIRS-2 measures thermal infrared radiation, or heat, emitted from the Earth’s surface. Landsat 9 improvements include higher radiometric resolution for OLI-2 (14-bit quantization increased from 12-bits for Landsat 8), enabling sensors to detect more subtle differences, especially over darker areas such as water or dense forests. With this higher radiometric resolution, Landsat 9 can differentiate 16,384 shades of a given wavelength. In comparison, Landsat 8 provides 12-bit data and 4,096 shades, and Landsat 7 detects only 256 shades with its 8-bit resolution. In addition to the OLI-2 improvement, TIRS-2 has significantly reduced stray light compared to the Landsat 8 TIRS, which enables improved atmospheric correction and more accurate surface temperature measurements. All commissioning and calibration activities show Landsat 9 performing just as well, if not better, than Landsat 8. In addition to routine calibration methods (i.e., on-board calibration sources, lunar observations, pseudo invariant calibration sites (PICS), and direct field in situ measurements), an underfly of Landsat 9 with Landsat 8 in mid-November 2021 provided cross-calibration between the two satellites’ onboard instruments, ensuring data consistency across the Landsat Collection 2 archive. Working in tandem with Landsat 8, Landsat 9 will provide major improvements to the nation’s land imaging, sustainable resource management, and climate science capabilities. Landsat’s imagery provides a landscape-level view of the land surface, surface waters (inland lakes and rivers) and coastal zones, and the changes that occur from both natural processes and human-induced activity. “Landsat 9 is distinctive among Earth observation missions because it carries the honor to extend the 50-year Landsat observational record into the next 50 years,” said Chris Crawford, USGS Landsat 9 Project Scientist. Partnered in orbit with Landsat 8, Landsat 9 will ensure continued eight-day global land and near-shore revisit.” Since October 31, 2021, Landsat 9 has collected over 57,000 images of the planet and will collect approximately 750 images of Earth each day. These images will be processed, archived, and distributed from the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota. Since 2008, the USGS Landsat Archive has provided more than 100 million images to data users around the world, free of charge. Landsat 9 is a joint mission between the USGS and NASA and is the latest in the Landsat series of remote sensing satellites. The Landsat Program has been providing global coverage of landscape change since 1972. Landsat’s unique long-term data record provides the basis for a critical understanding of environmental and climate changes occurring in the United States and around the world.

  3. The images above are released by the James Webb Space Telescope (JWST) team aren’t officially ‘first light’ images from the new telescope, but in a way, it feels like they are. These stunning views provide the initial indications of just how powerful JWST will be, and just how much infrared astronomy is about to improve. The images were released following the completion of the long process to fully focus the telescope’s mirror segments. Engineers are saying JWST’s optical performance is “better than the most optimistic predictions,” and astronomers are beside themselves with excitement. The astronomers and engineers actually seem astounded how good JWST’s resolution is turning out to be. The first official image of JWST will be released on July 12. https://scitechdaily.com/comparing-the-incredible-webb-space-telescope-images-to-other-infrared-observatories/

  5. A core task, which is solved most efficiently with the ImageStation photogrammetry environment, is the precise, interactive capture of 3D objects, the entire infrastructure, such as buildings, roads and bridges, but also natural terrain features. In Germany, the topographical surveying and updating / tracking of the entire infrastructure is the responsibility of the surveying offices in each of the 16 German states or ‘Laender’. The ImageStation was specially developed for professional photogrammetry and cartography users and provides a comprehensive set of data acquisition tools. In order to be able to move intuitively and measure precisely in this stereoscopic, three-dimensional reality, an important interface element was integrated into this high-tech software right from the beginning: the 3D stereo mouse cursor. The stereoscopic mouse cursor implementation is a prerequisite for working with precise 3D data controllers and enables perfect interaction with the plug & play compatible and powerful 3D PluraView monitor systems from Schneider Digital. The passive 3D monitors from Schneider Digital with beam-splitter technology impress by pixel-precise visualization of up to 4K (UHD) per stereo channel, fast image frame rate, high color depth, high brightness and contrast values. With its certification, Schneider Digital confirms that the powerful ImageStation® software suite is fully compatible with this professional hardware and thus meets all the requirements of international workplace standards: Two compatible cutting-edge technologies that merge into a complete solution and an ideal combination for professional photogrammetry users. The collection and updating of topographical geoinformation datasets is a complex task from a scientific, technical and organizational point of view. The comprehensive photogrammetry solutions from the Swedish metrology and geospatial software company HEXAGON support users worldwide in the acquisition, management and evaluation of multi-temporal, static and dynamic geospatial data. In order to convert particularly large amounts of raw data into easy-to-use and actionable information, HEXAGON has further developed the software application ImageStation®. More than 40 years of photogrammetric 'know-how' have gone into this modern application, starting with analytical stereoplotters and culminating in a complete software suite for digital photogrammetry, including a perfect stereoscopic 3D cursor implementation. Smooth GIS Workflow With its photogrammetry solutions, HEXAGON ensures a seamless workflow for the processing of high-resolution image data and geocoded CAD and GIS content from project start to finish. In classic aerial photogrammetry, project blocks are flown in laterally overlapping strips, whereby image overlaps of up to 90% in flight direction are realized and frame rates of 0.5 to 0.7 seconds represent the current state of the art. With the simultaneous recording of oblique aerial images, more than 3-GB of image data can be created for each exposure center. Project blocks with over 50,000 exposure stations, 5cm ground resolution and over 150-TB of initial image volume for urban areas, can now be commonly realized and calculated. Users of the ImageStation software suite benefit from the many interactive stereo functions of this powerful photogrammetry application: smooth roaming, dynamic zoom and real-time image enhancement are integrated directly into the GIS or CAD environment. The ability to perform stereo and mono compilation directly in a GIS environment enables direct comparison with and seamless continuation of existing GIS databases, resulting in a significant increase in efficiency. This not only saves valuable time and resources, but also reduces the cost of creating topologically correct 3D data. 3D-Cursor - integrated into software applications HEXAGON has perfectly implemented a professional, stereoscopic 3D cursor in the ImageStation. This functionality enables users to intuitively and smoothly navigate for the precise capture 3D objects with their real-world XYZ coordinates. In addition to the management components, the ImageStation Photogrammetric Manager (ISPM) and Image Formatter (ISIF), the applications with integrated 3D cursor function include the ImageStation Automatic Triangulation (ISAT), ImageStation Satellite Triangulation (ISST), ImageStation Feature Collection (ISFC), ImageStation Stereo Display (ISSD), ImageStation Stereo for GeoMedia (ISSG), ImageStation Stereo Viewer GeoMedia (ISSV), ImageStation DTM Collection (ISDC), ImageStation DTM for GeoMedia (ISDG) and ImageStation Automatic Elevations (ISAE). The calculation programs ImageStation Automatic Elevations DSM (ISAD) and ImageStation OrthoPro (ISOP) run in batch mode. Interactive again is the computer-assisted editing and quality control with ImageStation DTMQue (ISDQ) and ImageStation PixelQue (ISPQ). Process geospatial data quickly and precisely The photogrammetric ImageStation software suite is used worldwide and especially at state surveying offices and by users from industries such as aviation, shipping and national defense. With the ImageStation, geospatial data can be processed quickly, efficiently and cost-effectively. For example, the ImageStation Stereo Display (ISSD) application supports viewing and editing of stereo images with photogrammetrically accurate 3D-cursor tracking. ISSD accepts aerial or satellite data, images from drone (UAS) projects, as well as from the Leica ADS 3-line cameras. The ImageStation Suite enables the automatic and dynamic adjustment of image brightness and contrast in the MicroStation and GeoMedia environment. The exclusive ImageStation ImagePipe technology is responsible for smooth stereo roaming, providing the perfect image representation that is essential for efficient stereo compilation. Stereoscopic geospatial data acquisition and processing HEXAGON ImageStation Stereo for GeoMedia (ISSG) is based on the GeoMedia geospatial information system (GIS) and provides the user with a comprehensive selection of intelligent compilation tools. This powerful software environment allows access to practically any geodatabase and version of geospatial datasets. With this software application, airborne, satellite and UAS data are displayed in an intelligent GIS environment with multiple, freely configurable mono and/or stereo windows. Same as the ImageStation Stereo Display (ISSD) with MicroStation, ISSG supports viewing and editing of stereo images with photogrammetrically accurate 3D-cursor tracking. ISSG offers many practical tools for the interactive acquisition and updating of geospatial datasets. It enables the interactive updating of 3D-object geometry and attributes, as well as automatic attribution and geometry validation. Geospatial data generated in this way can be stored in an open database format so that third parties have seamless access to them through their respective GIS systems. The creation of digital surface models (DSM) from optical stereo data is also part of the functionalities, offered by the ImageStation suite. The software applications display topographical data, both raster and vector-based, so well-structured that they are easy to edit and efficient to use. With the help of a 'snap cursor', which snaps automatically to the selected feature, a quick check of the correct object selection is possible. Together with the "Elevation" command, contour lines are created interactively. To correct for the individual depth perception of each operator, vertical indexing is used to adjust and thereby calibrate manual height measurements. Full performance by 3D-stereo visualization Computationally intensive reconstruction algorithms are responsible for the razor-sharp, three-dimensional generation and display of geometric and georeferenced models made up by dense point clouds. The 3D PluraView monitors from Schneider Digital, the world's leading specialist for stereoscopic 3D desktop visualization solutions, provide the key to perfect 3D-stereo visualization for these professional geospatial application areas. The beam splitter technology meets the highest system requirements in the areas of 4K displays, 3D and VR/AR technology to display geographical map material and high-resolution GIS data in perfect 3D-stereo quality. The high brightness and contrast, full resolution for each stereo channel thanks to two screens and complete freedom from any flickering effects, guarantee a perfect 3D-stereo experience and make it easier to analyze and edit 3D content. The 3D PluraView monitors render 3D objects clearly visible even in darker image areas and are free from blurring effects for rapidly moving images thanks to a latency-free, fully synchronous display of the two stereo channels. ImageStation - certified for the 3D PluraView monitors As tried and tested technology for the past 17 years, the cutting-edge 3D-stereo displays from Schneider Digital are 'plug & play' certified for photogrammetry and GIS and perfectly compatible with the ImageStation® modules. The full compatibility of the ImageStation® software with the 3D PluraView monitor family has now been officially certified by the manufacturer Schneider Digital. The seal of certification ensures that the combination of the 3D PluraView hardware with the respective software application meets the high requirements of international standards in terms of quality and workplace ergonomics. For an optimal photogrammetric workflow, the ImageStation® offers a fully integrated software solution together with the associated hardware components by Schneider Digital. In addition to the 3D PluraView monitor, these are powerful workstations based on CPUs by Intel or AMD, professional RTX graphic cards from NVIDIA and Radeon Pro graphics cards from AMD, and of course the Stealth 3D controllers. In conjunction with the native implementation of the stereoscopic mouse cursor in the Hexagon ImageStation suite, the Stealth 3D controllers enable the spatial navigation to 3D objects, which can then precisely measured and captured.  ImageStation stereo functions and display tools - advantages for the 3D PluraView user: • High contrast and brightness of the 3D PluraView monitors, combined with flicker-free stereo viewing through light-weight passive stereo glasses, allows long-term, comfortable use and therefore higher productivity • Smooth stereo roaming and dynamic zoom thanks to the ImageStation's exclusive ImagePipe technology for continuous stereo display of very large datasets • Easy navigation in stereo models with mouse, keyboard, the Stealth 3D mouse or by graphical selection in a 2D map view • Automated correlation of the exact XYZ position of objects with the 'Cursor-on-Surface' function • Display rotation for additional validation of vector data • Synchronized display of stereoscopic and monoscopic map views for controlled feature collection and review • GIS data in 2D (only XY coordinates) is displayed under the position of the stereo cursor in the 3D environment, also allowing accurate updating of 2D data • Streamlines workflow by performing stereo- and mono-data collection directly in a powerful GIS environment • Better interpretation of image information in 3D-stereo, compared to the interpretation of single images, elimination of 3D parallax enables precise measurements • Reduces the cost of creating accurate and topologically correct 3D datasets, saving significant time and resources

  7. This is first image from NASA’s James Webb Space Telescope is the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground. President Joe Biden unveiled this image of galaxy cluster SMACS 0723 during a White House event Monday, July 11. NASA The $10bn James Webb Space Telescope (JWST), launched on 25 December last year, is billed as the successor to the famous Hubble Space Telescope. It will make all sorts of observations of the sky, but has two overarching goals. One is to take pictures of the very first stars to shine in the Universe more than 13.5 billion years ago; the other is to probe far-off planets to see if they might be habitable. One of the topics to be discussed will touch on that other overarching goal: the study of planets outside our Solar System. Webb has analysed the atmosphere of WASP-96 b, a giant planet located more than 1,000 light-years from Earth. It will tell us about the chemistry of that atmosphere. WASP-96 b orbits far too close to its parent star to sustain life. But, one day, it's hoped Webb might spy a planet that has gases in its air that are similar to those that shroud the Earth - a tantalising prospect that might hint at the presence of biology.

  8. That's not all, this is a major release which requires NET 6. There's a new License Manager too 😉. ... but there will be workarounds. A new start page and a Learn Page. Geoprocessing tools will display an information tip letting you know when a selection or other filter is applied to input layers and the number of records that will be processed. You will also see tool parameter memory and autofill for commonly used tools accessed from the ribbon and context menus. Color Vision Deficiency Simulator. Then there is SAR toolset, Neo4S support to link charts and data from NoSQL, support more CAD and BIM formats etc.

  9. For most uses, Google Maps is a flat, 2D app, and if your device can handle more graphics and a bit more data, you can fire up the Google Earth 3D data set and get 3D buildings. At Google I/O Google has announced a new level that turns the graphics slider way, way up on Google Maps: Immersive View. When exploring an area in Google Maps, the company says Immersive View will make it "feel like you’re right there before you ever set foot inside." The video for this feature is wild. It basically turns Google Maps into a 3D version of SimCity with AAA video game graphics. There are simulated cars that drive through the roads, and birds fly through the sky. Clouds pass overhead and cast shadows on the world. The weather is simulated, and water has realistic reflections that change with the camera. London even has an animated Ferris wheel that spins around. Google can't possibly be tracking things like the individual positions of birds (yet!), but a lot of this is real data. The cars represent the current traffic levels on a given street. The weather represents the actual weather, even for historical data. The sun moves in real time with the time of day. Another part of the video shows flying into a business that also has a whole 3D layout. All of this is possible thanks to combining the massive data sets from Google Maps, Google Earth, and Street View, but even then, this level of fidelity will be very limited by the initial data sets. Google says that at first, Immersive View will "start... rolling out in Los Angeles, London, New York, San Francisco, and Tokyo later this year with more cities coming soon." The company says that "Immersive view will work on just about any phone and device," but just like the 3D building mode, this will be an optional toggle.

  10. Governments and businesses across the world are pledging to adopt more sustainable and equitable practices. Many are also working to limit activities that contribute to climate change. To support these efforts, Esri, the global leader in location intelligence, in partnership with Impact Observatory and Microsoft, is releasing a globally consistent 2017–2021 global land-use and land-cover map of the world based on the most up-to-date 10-meter Sentinel-2 satellite data. In addition to the new 2021 data, 10-meter land-use and land-cover data for 2017, 2018, 2019, and 2020 is included, illustrating five years of change across the planet. This digital rendering of earth’s surfaces offers detailed information and insights about how land is being used. The map is available online to more than 10 million users of geographic information system (GIS) software through Esri’s ArcGIS Living Atlas of the World, the foremost collection of geographic information and services, including maps and apps. “Accurate, timely, and accessible maps are critical for understanding the rapidly changing world, especially as the effects of climate change accelerate globally,” said Jack Dangermond, Esri founder and president. “Planners worldwide can use this map to better understand complex challenges and take a geographic approach to decisions about food security, sustainable land use, surface water, and resource management.” Esri released a 2020 global land-cover map last year as well as a high-resolution 2050 global land-cover map, showing how earth’s land surfaces might look 30 years from now. With the planned annual releases, users will have the option to make year-to-year comparisons for detecting change in vegetation and crops, forest extents, bare surfaces, and urban areas. These maps also provide insights about locations with distinctive land use/land cover, as well as human activity affecting them. National government resource agencies use land-use/land-cover data as a basis for understanding trends in natural capital, which helps define land-planning priorities and determine budget allocations. Esri’s map layers were developed with imagery from the European Space Agency (ESA) Sentinel-2 satellite, with machine learning workflows by Esri Silver partner Impact Observatory and incredible compute resources from longtime partner Microsoft. The Sentinel-2 satellite carries a range of technologies including radar and multispectral imaging instruments for land, ocean, and atmospheres, enabling it to monitor vegetation, soil and water cover, inland waterways, and coastal areas. “World leaders need to set and achieve ambitious targets for sustainable development and environmental restoration,” said Steve Brumby, Impact Observatory cofounder and CEO. “Impact Observatory [and] our partners Esri and Microsoft are once again first to deliver an annual set of global maps at unprecedented scale and speed. These maps of changing land use and land cover provide leaders in governments, industry, and finance with a new AI [artificial intelligence]-powered capability for timely, actionable geospatial insights on demand.” Esri and Microsoft have released this 10-meter-resolution time-series map under a Creative Commons license to encourage broad adoption and ensure equitable access for planners working to create a more sustainable planet. Users can manipulate the map layers and other data layers with GIS software to create more dynamic visualizations. In addition to being freely available in ArcGIS Online as a map service, these resources are also available for download and viewing.

  16. Let's say goodbye to Landsat 7 and say hello to Landsat 9 ! Landsat-9 will replace Landsat 7 in its orbit. The new OLI-2 and TIRS-2 sensors of the Landsat 9 will be a slight improvement from its predecessor. According to the overview, the spatial and spectral resolution remains the same - moderate spatial resolution—15 m, 30 m, and 100 m depending on spectral band—and the ability to detect the same range in intensity as Landsat 8, or better The OLI–2 will capture observa­tions of the Earth’s surface in visible, near-infrared, and shortwave-infrared bands with an improved radiometric precision (14-bit quantization increased from 12 bits for Landsat 8), slightly improving overall signal to noise ratio TIRS-2 will measure thermal radiance emitted from the land surface in two thermal infrared bands using the same technology that was used for TIRS on Landsat 8, however TIRS-2 will be an improved version of Landsat 8’s TIRS, both with regards to instrument risk class and design to minimize stray light Both OLI–2 and TIRS–2 have a 5-year mission design life, although the spacecraft has 10+ years of consumables Here are the spectral bands from OLI-2, Band 1 Visible (0.43 - 0.45 µm) 30-m Band 2 Visible (0.450 - 0.51 µm) 30-m Band 3 Visible (0.53 - 0.59 µm) 30-m Band 4 Red (0.64 - 0.67 µm) 30-m Band 5 Near-Infrared (0.85 - 0.88 µm) 30-m Band 6 SWIR 1(1.57 - 1.65 µm) 30-m Band 7 SWIR 2 (2.11 - 2.29 µm) 30-m Band 8 Panchromatic (PAN) (0.50 - 0.68 µm) 15-m Band 9 Cirrus (1.36 - 1.38 µm) 30-m Two spectral bands from TIRS-2, Band 10 TIRS 1 (10.6 - 11.19 µm) 100-m Band 11 TIRS 2 (11.5 - 12.51 µm) 100-m The good thing is Landsat 9 will image the Earth every 16 days in an 8-day offset with Landsat 8, which means increased temporal coverage of observations.

  17. The topic that counts is interesting and that is the way to do good work when we have to present a project. Unfortunately for us that we do not have a solution like Erdas. The Hexagon company evolves every day and presents many solutions but at the business level, it talks about opportunities for students but I do not know their prices. Esri at least provides an opportunity and we know it costs. Thanks for your comments and any ideas to bring that workflow into cheaper or open access solutions. Lurker successes.
