    Earth's interior is swallowing up more carbon than thought

    Lurker
    By Lurker,
    Scientists from Cambridge University and NTU Singapore have found that slow-motion collisions of tectonic plates drag more carbon into Earth's interior than previously thought. They found that the carbon drawn into Earth's interior at subduction zones—where tectonic plates collide and dive into Earth's interior—tends to stay locked away at depth, rather than resurfacing in the form of volcanic emissions. Their findings, published in Nature Communications, suggest that only about a thir

    Honeywell debuts MEMS sensor to help small sats navigate

    Lurker
    By Lurker,
    Honeywell has unveiled a new rate sensor to help small satellites navigate increasingly crowded orbits above the Earth’s surface. The new micro-electro-mechanical system (MEMS)-based product provides low cost and power consumption in a smaller size than previous Honeywell offerings, while maintaining high performance levels. It is suitable for customers building smaller and lower-cost satellites, according to Honeywell. Honeywell’s HG4934 space rate sensor is roughly the same size and weigh

    Esri UC 2021: What's new and what's not

    By rahmansunbeam,
    The all-virtual Esri User Conference 2021 just dropped the curtain after a four-day event. Here's whats new. Everything new explained by Jack Dangermond. ArcGIS Image is a software for remote sensing over cloud. ArcGIS Velocity gets real-time data visualization maps. ArcGIS Enterprise installation using Kubernetes. More experiments with field survey. 😑 More integrated BIM for ArcGIS. Maps SDK

    UN confirms 18.3C record on temperature in Antarctica

    Lurker
    By Lurker,
    The United Nations on Thursday recognised a new record high temperature for the Antarctic continent, confirming a reading of 18.3 degrees Celsius (64.9 degrees Fahrenheit) made last year. The record heat was reached at Argentina's Esperanza research station on the Antarctic Peninsula on February 6, 2020, the UN's World Meteorological Organization said. "Verification of this maximum temperature record is important because it helps us to build up a picture of the weather and climate in o

    2020 Global Land Use Data

    Lurker
    By Lurker,
    A global land cover GeoTIFF was recently released by Impact Observatory (IO) and Esri. To create this geospatial layer, hundreds of thousands of satellite photos were classified into ten unique land use/land cover (LULC) classes using a deep learning model in partnership with Microsoft AI for Earth. Sentinel-2 imagery was used to divide the world into ten categories of land use cover: Water (areas that are predominately water such as rivers ponds, lakes, and ocean) Trees (clusters

    • Interesting update!  I see they introduced IDL for VSCode as well, also an 'IDL Notebook'. I will give these new tools some time to mature before a proper test drive.  
    • Medicine of Envi 6 please!!!! 😇
    • Added support for data types: GRUS L1C, L2A - Axelspace micro-earth observation satellite ISIS3 - USGS Astrogeology ISIS Cube, Version 3 PDS4 -NASA Planetary Data System, Version 4 New Spectral Hourglass Workflow and N-Dimensional Visualizer   New Target Detection Workflow The Target Detection Workflow has been added to this release. Use the Target Detection Workflow to locate objects within hyperspectral or multispectral images that match the signatures of in-scene regions. The targets may be a material or mineral of interest, or man-made objects. New Dynamic Band Selection tool New Material Identification tool Updated and improved Endmember Collection tool New and updated ENVI Toolbox tools The following tools have been updated to use new ENVI Tasks: Adaptive Coherence Estimator Classification: A classification method derived from the Generalized Likelihood Ratio (GLR) approach. The ACE is invariant to relative scaling of input spectra and has a Constant False Alarm Rate (CFAR) with respect to such scaling. Constrained Energy Minimization Classification: A classification method that uses a specific constraint, CEM uses a finite impulse response (FIR) filter to pass through the desired target while minimizing its output energy resulting from a background other than the desired targets. Classification Smoothing: Removes speckling noise from a classification image. It uses majority analysis to change spurious pixels within a large single class to that class. Forward Minimum Noise Fraction: Performs a minimum noise fraction (MNF) transform to determine the inherent dimensionality of image data, to segregate noise in the data, and to reduce the computational requirements for subsequent processing. Inverse Minimum Noise Fraction: Transforms the bands from a previous Forward Minimum Noise Fraction to their original data space. Orthogonal Subspace Projection Classification: This classification method first designs an orthogonal subspace projector to eliminate the response of non-targets, then Matched Filter is applied to match the desired target from the data. Parallelepiped Classification: Performs a parallelepiped supervised classification which uses a simple decision rule to classify multispectral data. Spectral Information Divergence Classification: A spectral classification method that uses a divergence measure to match pixels to reference spectra. New and updated ENVI Tasks You can use these new ENVI Tasks to perform data-processing operations in your own ENVI+IDL programs: ConstrainedEnergyMinimization: Performs the Constrained Energy Minimization (CEM) target analysis. InverseMNFTransform: Transforms the bands from a previous Forward Minimum Noise Fraction to their original data space. MixtureTunedRuleRasterClassification: Applies threshold and infeasibility values and performs classification on mixture tuned rule raster. MixtureTunedTargetConstrainedInterferenceMinimizedFilter: Performs the Mixture Tuned Target-Constrained Interference-Minimized Filter (MTTCIMF) target analysis. NormalizedEuclideanDistanceClassification: Performs a Normalized Euclidean Distance (NED) supervised classification. OrthogonalSubspaceProjection: Performs the Orthogonal Subspace Projection (OSP) target analysis. ParallelepipedClassification: This task performs a parallelepiped supervised classification which uses a simple decision rule to classify multispectral data. RuleRasterClassification: Creates a classification raster by thresholding on each band of the raster. SpectralInformationDivergenceClassification: Performs the Spectral Information Divergence (SID) classification. SpectralSimilarityMapperClassification: Performs a Spectral Similarity Mapper (SSM) supervised classification. TargetConstrainedInterferenceMinimizedFilter: Performs the Target-Constrained Interference-Minimized Filter (TCIMF) target analysis.

    • some of file hosting known to use some kind of client software mandatory to download their file, like for example pan baidu or terrabox and many more, I tend to avoid those type of file hosting btw, there are already topic related to this software, here: I will close this topic
