    China completes core of Beidou global satellite navigation system

    Lurker
    By Lurker,
    Two Chinese Beidou navigation satellites successfully launched Monday on top of a Long March 3B rocket, completing the core of China’s independent positioning and timing network ahead of the start of global service next year.   The 184-foot-tall (56-meter) Long March 3B rocket lifted off from the Xichang space base in southwestern China’s Sichuan province at 0722 GMT (2:22 a.m. EST; 3:22 p.m. Beijing time) Monday, according to statements issued by the country’s top state-owned aero

    Automated Remote Sensing of Underground Features

    Lurker
    By Lurker,
    While many advancements have  been made this last decade in automated classification of above surface features using remote sensing data, progress for detecting underground features has lagged in this area. Technologies for detecting features, including ground penetrating radar, electrical resistivity, and magnetometry exist, but methods for feature extraction and identification mostly depend on the experience of instrument user. One problem has been creating approaches that can deal with c

    Open Repository for Geospatial Training Data Released

    Lurker
    By Lurker,
    Radiant Earth has launched Radiant MLHub, a cloud-based open library for training geospatial data used by machine learning algorithms.  In launching the repository, Radiant Earth noted that while there is an abundance of satellite imagery, there is a lack of training data and tools to train machine learning algorithms.  Radiant MLHub is a federated site for the discovery and access of high-quality Earth observation (EO) training datasets and machine learning models.  Individuals and organization

    QGIS and ENVI Classifier Comparison

    Shahrul
    By Shahrul,
    Hi All, Hopefully this group can give me answer on my Question.   First round,   I use EnMAP Box 3 which is plugin in QGIS. I use it for image classification which the result is classified image into 7 class in BSQ format. The algorithm I use for classification is Random Forest, Gaussian and LinearSVC.   EnMap use my Training ROI to proses in Random Forest, Gaussian and LinearSVC classifier/algorithm. But on accuracy assessment EnMAP (Random Forest, Gau

    • A plug-in to integrate Google Earth Engine with QGIS using Python API. Usage Step 1: Sign up for Google Earth Engine. Step 2: Install QGIS. Step 3: Install the Google Earth Engine Plugin for QGIS and authenticate Google Earth Engine. Step 4: Git clone or download this repository. Step 5: Open the Python console in QGIS and load any downloaded Python script into the QGIS Python Editor. Step 6: Click the Run script button on the Python Editor to execute the script. Step 7: Zoom in/out the QGIS Canvas to inspect the results. Installation and getting started Examples Get Started Hello world!

    • anyone tried erase tools and get success ?
    • Thank you for your efforts to fix v10.8.1, since it is probably the last version of ArcGIS for Desktop. I wish it were stable and fully working like ArcGIS 10.2.2 is.
    • nice share AG10.8.1 ...amazing !!!
