GEE GPR Phenology
A QGIS plugin for Sentinel-2 biophysical variable retrieval, temporal gap filling, and land surface phenology analysis using Gaussian Process Regression.
GEE GPR Phenology implements a complete workflow for Sentinel-2 BOA/L2A imagery, including spectral GPR prediction, temporal gap filling with an RBF kernel, double logistic fitting, and land surface phenology metrics such as SOS, EOS, POS and LOS. Since version 1.5.0, the plugin includes automatic layer loading with QGIS symbology and groups, PDF/CSV reports, heterogeneous raster grid correction for LSP processing, duplicate-date handling, and multilingual support in Spanish, English and Portuguese. Version 1.5.14 keeps QGIS 3.x to QGIS 4.x availability, preserves the Qt5/Qt6 compatibility fixes, preserves the assisted dependency launcher, and completes the QGIS Plugin Repository code-quality cleanup without changing the mathematical or modelling logic. Note for QGIS 4.0.x / Python 3.12: in some installations, functional libraries such as rasterio may not be available in the QGIS Python environment by default. If rasterio is missing, GEE download may work but raster harmonization, gap filling, GPR raster prediction, or LSP processing can stop with ModuleNotFoundError. Use the plugin Info tab / dependency assistant or install rasterio in the QGIS Python environment before running those workflows. If QGIS 4 does not expose a valid python.exe/python3, the assistant stops safely and shows manual instructions instead of opening a new QGIS instance. QGIS 3.x testing remains the recommended production path until all required Python wheels are confirmed in the target QGIS 4 environment. This release does not change the mathematical or modelling logic.
