    Doubt of GUIDOS Toolbox and ArcGIS ( Fragmentation - FAD )

    Estoico
    By Estoico,
    Hi, everybody I'm writing to find out if you can help me with a question about GUIDOS Toolbox and its subsequent analysis in ArcGIS. I have been using MSPA to reclassify the image byte values and get the corresponding morphological classes in ArcGIS, but the FAD result values that guide me in the reclassification are not available, so I would like to know if anyone knows how to convert the 255 byte values of the GeoTiff images obtained in GUIDOS to result in the 6 fragmentation c

    Gridded Population of the World v4 available

    By Lurker,
    The Gridded Population of the World (GPW) collection, now in its fourth version (GPWv4), models the distribution of human population (counts and densities) on a continuous global raster surface. Since the release of the first version of this global population surface in 1995, the essential inputs to GPW have been population census tables and corresponding geographic boundaries. The purpose of GPW is to provide a spatially disaggregated population layer that is compatible with data sets from soci

    Computer-based weather forecast: New algorithm outperforms mainframe computer systems

    Lurker
    By Lurker,
    New algorithm solves complex problems more easily and more accurately on a personal computer while requiring less processing power than a supercomputer The exponential growth in computer processing power seen over the past 60 years may soon come to a halt. Complex systems such as those used in weather forecast, for example, require high computing capacities, but the costs for running supercomputers to process large quantities of data can become a limiting factor. Researchers at Johannes G

    Interactive coronavirus heat map shows spread of virus around the world

    Lurker
    By Lurker,
    Johns Hopkins University has put out a heat map in response to the public health emergency that updates the number of confirmed coronavirus cases across the world. According to its website, the map was developed using data from WHO, CDC, China CDC, China National Health Commission and Dingxiangyuan – a website which reportedly aggregates data from Chinese government sources in “near real-time.” As of Friday, more than 900 cases of coronavirus have been confirmed and 26 people have died

    Huawei with Tomtom create mapping data as a Google Maps alternative

    Lurker
    By Lurker,
    With Huawei basically blocked from using Google services and infrastructure, the firm has taken steps to replace Google Maps on its hardware by signing a partnership with TomTom to provide maps, navigation, and traffic data to Huawei apps. Reuters reports that Huawei is entering this partnership with TomTom as the mapping tech company is based in the Netherlands — therefore side-stepping the bans on working with US firms. TomTom will provide the Chinese smartphone manufacturer with mapping,

    • 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 !!!
