Supervised classification in QGIS || A complete Tutorial || 100%
Просмотров 24 тыс.2 года назад
Supervised classification is based on the idea that a user can select sample pixels in an image that are representative of specific classes and then direct the image processing software to use these training sites as references for the classification of all other pixels in the image. In this tutorial, I demonstrate how to carry out supervised classification in QGIS. Enjoy

Object-based image analysis (OBIA) involves pixels first being grouped into objects based on either spectral similarity or an external variable such as ownership, soil or geological unit.An Object Based Image Analysis (OBIA) approach to image classification segments an image into homogenous spectral regions. This differs from standard image analysis methods that classify each pixel in isolation...

    For QGIS 3.34, before following these steps, you need to go to 'Plugins', select 'ALL' and search for 'OrfeoToolbox provider', once it shows, check the box near it and close the Plugins window. This solves the problem of OTB not appearing in the settings --> processing.

    Hello, sir. My problem is that when I export separate map pieces from the world map, such as Bing Satellite, for example, if I have a small country map, it gets blurred. This is because it requires a lot of zooming compared to larger countries, and I can't change the zoom specifically for it since i don't want to mess with the spacing when adding it back to my video editor for map animation. Is there any workaround to make it very high quality?
