    ENVI to Arcmap

    Ghazal
    By Ghazal,
    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

    GlobalMapper 21.1 WFS GML problem

    Capricorn
    By Capricorn,
    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.

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 c

    arcgis pro or arcmap?

    intertronic
    By intertronic,
    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 s

    Introducing ArcGIS Living Atlas Indicators of the Planet

    Lurker
    By Lurker,
    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 gathe

    • Satellite images analyzed by AI are emerging as a new tool in finding unmapped roads that bring environmental destruction to wilderness areas. James Cook University's Distinguished Professor Bill Laurance was co-author of a study analyzing the reliability of an automated approach to large-scale road mapping, using convolutional neural networks trained on road data, using satellite images. He said the Earth is experiencing an unprecedented wave of road building, with some 25 million kilometers of new paved roads expected by mid-century. "Roughly 90% of all road construction is occurring in developing nations including many tropical and subtropical regions of exceptional biodiversity. "By sharply increasing access to formerly remote natural areas, poorly regulated road development triggers dramatic increases in environmental disruption due to activities such as logging, mining and land clearing," said Professor Laurance. He said many roads in such regions, both legal and illegal, are unmapped, with road-mapping studies in the Brazilian Amazon, Asia-Pacific and elsewhere regularly finding up to 13 times more road length than reported in government or road databases. "Traditionally, road mapping meant tracing road features by hand, using satellite imagery. This is incredibly slow, making it almost impossible to stay on top of the global road tsunami," said Professor Laurance. The researchers trained three machine-learning models to automatically map road features from high-resolution satellite imagery covering rural, generally remote and often forested areas of Papua New Guinea, Indonesia and Malaysia. "This study shows the remarkable potential of AI for large-scale tasks like global road-mapping. We're not there yet, but we're making good progress," said Professor Laurance. "Proliferating roads are probably the most important direct threat to tropical forests globally. In a few more years, AI might give us the means to map and monitor roads across the world's most environmentally critical areas." journal: https://www.mdpi.com/2072-4292/16/5/839

    • BAE Systems is celebrating alongside its customers at the Environmental Defense Fund (EDF) following the successful launch of the MethaneSAT satellite from Vandenberg Space Force Base in California today. The satellite will provide the public with reliable scientific data about the sources and scale of methane emissions globally, with the ultimate goal of driving reductions in the near future. MethaneSAT’s primary instrument includes a BAE Systems-built spectrometer that will identify and quantify methane emissions by measuring the narrow part of the infrared spectrum where the gas absorbs light reflected off the Earth MethaneSAT’s primary instrument includes a BAE Systems-built spectrometer that will identify and quantify methane emissions by measuring the narrow part of the infrared spectrum where the gas absorbs light reflected off the Earth. The satellite will monitor emissions from the oil and gas sector, which accounts for about 40% of all human-caused methane emissions, and it will be able to revisit the same sites daily in most instances. MethaneSAT will also fill a gap in existing remote methane monitoring capabilities, offering high-precision emissions mapping over a broad 200km by 200km field of view. This satellite will further complement existing methane-monitoring satellites that focus on either larger scales or detecting point sources.   “MethaneSAT will make a critical difference in helping us better understand and remedy global greenhouse gas emissions,” said Dr. Alberto Conti, vice president and general manager of Civil Space for BAE Systems Space & Mission Systems. “MethaneSAT will advance our ability to identify and track emissions from their source, empowering stakeholders and the public with actionable data to enable reductions. We are thankful to our customers at the Environmental Defense Fund for developing this crucial mission, and we look forward to seeing all the change it will bring.” BAE Systems worked alongside scientists from EDF and MethaneSAT, LLC, to design and build the primary instrument. The company also led spacecraft integration, environmental testing, and will provide commissioning services. Once commissioning is complete, EDF will launch a cloud-based platform in partnership with Google to distribute MethaneSAT data publicly and free of charge, ensuring the data will be easily accessible for all. “MethaneSAT is a unique instrument with demanding specifications,” said Peter Vedder, senior director for mission systems at MethaneSAT. “It’s designed to see methane emissions that other satellites can’t, with unprecedented precision. BAE Systems helped us push the envelope to deliver a powerful new tool for protecting the climate.” MethaneSAT launched on a SpaceX Falcon 9 rocket.  
    • The National Research and Innovation Agency (BRIN) uses remote sensing technology to calculate the danger of faults as an effort to mitigate the threat of earthquakes for the public. A researcher from BRIN's Geological Disaster Research Center, Nurani Rahma Hanifa, stated that her side was collaborating with the British Geological Survey (BGS) in this technology research that has been published in a joint scientific research. "We hope this effort can reduce the fatality caused by earthquakes with the scientific data we have through remote sensing," she noted in a statement from her office on Thursday. Meanwhile, BGS' geologist in multi-hazard and remote sensing, Ekbal Hussain, stated that the technology, currently owned by BGS, can measure ground movement patterns and details of earthquake fragments after an earthquake occurred from space using remote sensing. "Through detailed modeling, this technology can help us to understand that earthquakes have energy released, but there is also energy stored in the earth," Hussain stated. Regarding the Lembang Fault, he explained that remote sensing can estimate the danger of the Lembang Fault by monitoring energy stored in the fault and how much of it will be released when an earthquake occurs. He expressed hope that the use of remote sensing technology would save several lives, considering that the earthquakes' vulnerability is dynamic. Head of BRIN's Geological Disaster Research Center, Adrin Tohari, stated that the Cianjur earthquake that struck in 2022 was interesting to be studied deeper. He noted that until now, the fault location is not yet discovered, but the impact of damage caused by the fault is quite extensive. In 2023, BRIN had conducted a study to determine the main earthquake location. However, the agency had not found the main earthquake's vein due to thick volcanic deposits. "Activity is difficult to detect," Tohari stated. He is optimistic that the implementation of remote sensing technology would improve the scientists' ability of understanding the potential and risks of the Lembang Fault in the Greater Bandung area.
