Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Create management zones from rasters using PCA and K-Means with Elbow and Silhouette metrics, plus resampling, variance-reduction analysis, optional zone smoothing (Mode Filter), and rich CSV/PNG exports.
About
Features: - Resampling & raster value extraction inside a boundary. - PCA with explained variance table (incl. Eigenvalue λ) and CSV export. - K-Means clustering with Elbow curve and Silhouette score; export indices; generate zones as a raster. - Optional zone smoothing (Mode Filter): SAGA Majority/Minority. - Variance Reduction analysis from zones and external points CSV; per-zone statistics and boxplots (PNG).
