Spectral Harbor
Download selected Sentinel-2A and Landsat 8/9 surface-reflectance bands in QGIS Processing.
Spectral Harbor is a standalone QGIS 4 plugin for downloading selected surface-reflectance bands from Sentinel-2A Level-2A and Landsat 8/9 Collection 2 Level-2 through Earth Search.
Choose the satellite, area, dates, scene-cloud limit and bands. Create a single-scene image or a temporal median. Output pixels default to 10 m for Sentinel-2A and 30 m for Landsat; Sentinel bands with native 20/60 m resolution are resampled to the chosen grid.
Spectral Harbor handles image reading, sensor-specific reflectance normalization, quality layers and temporal compositing in a separate processing task. It runs independently and does not require another QGIS plugin.
Results are Float32 GeoTIFFs with -9999 nodata, native processing metadata, and descriptive Float32 filenames (e.g. S2A_YYYYMMDD_<SceneID>_BOA_Float32.tif) that are loaded into QGIS with matching layer titles. Median runs also create the original count, standard-deviation and water-occurrence outputs. Existing water options follow the upstream single-scene/composite behavior.
