Cloud removal from sentinel 2
Builds a cloud-free Sentinel-2 mosaic for a date range, over a Vietnamese province or commune or over a rectangle drawn anywhere.
Searches Sentinel-2 surface reflectance (COPERNICUS/S2_SR_HARMONIZED), masks clouds with COPERNICUS/S2_CLOUD_PROBABILITY at a threshold you set, and mosaics the date range into one composite. The area of interest is a Vietnamese administrative unit (province or commune, 2025 units, read from bundled GeoJSON and searchable by typing) or a rectangle drawn on the canvas, which works worldwide. A preview gallery shows one thumbnail per acquisition day with its cloud cover, so a cloudy range can be narrowed before downloading. RGB, NDVI and NBR are added to the map and can be exported to Google Drive. The interface is bilingual, English and Vietnamese. Requirements: this plugin does not process imagery locally, it needs the "Google Earth Engine" plugin installed in the same QGIS profile, signed in with a registered Earth Engine account, plus an internet connection. Exports are written to the Google Drive of that account and run as Earth Engine tasks. Restrictions: the bundled administrative boundaries cover Vietnam only, other regions must use the rectangle tool.
