Web4 de mai. de 2024 · Raster clustering using QGIS. I'm looking for a way to convert a classified raster into polygons based on spatial clusters within each class. For the clusters to be considered as valid I need them to consist of a minimum percentage of cells from one of the classes. For example: An area made up of 70 % (or more) cells of class "1" will be ... Web1 de fev. de 2024 · All of the parameters that describe accuracy presented lower values for small water bodies, especially for a water surface area beneath 0.5 ha, which represents a 50-pixel area in a Sentinel-2 10-m resolution image. For that class, the clustering technique presented much better results than other techniques, with a mean kappa of 0.47, a mean ...
