{"name": "HyperSpectral Processer", "package_name": "hyperspatial_processing", "description": "Local, parallel hyperspectral processing in QGIS: spectral indices, PCA and Spectral Angle Mapper target detection via an external multi-core C++ engine (OpenMP, optional OpenCL GPU).", "about": "Single-purpose, local-first QGIS plugin from Digital University Kerala for hyperspectral image processing. It drives an external C++/OpenMP/OpenCL engine to process hyperspectral rasters entirely on local hardware, writing results as GeoTIFF or VRT layers and loading them straight into the QGIS canvas. All per-pixel math runs in the native engine to keep large scenes off the Python heap. The plugin ships binary-free: the engine is located at run time from a configured path or the system PATH, or downloaded with one click from the project's GitHub Releases (or built from the hpc-engine source in the repository).\n.\nThree operations are selectable from one uncluttered dialog: (1) Spectral indices - NDVI, NDWI, NDBI, SAVI, EVI, NDMI and MSAVI; (2) PCA - principal-component dimensionality reduction producing false-colour PC composites (covariance or correlation matrix); (3) SAM - Spectral Angle Mapper reflectance-based target detection from a reference pixel picked on the map, with an optional detection mask and similarity band. Compute runs on all CPU cores with OpenMP (a full 224-band EnMAP scene in a few seconds on a laptop, memory bounded by thread count); an optional OpenCL GPU backend works on Apple, NVIDIA, Intel and AMD GPUs and falls back to the CPU automatically.", "homepage": "https://github.com/aaron43210/HYPERSPECTRAL_DATA_DISTRIBUTED_SYSTEM", "repository": "https://github.com/aaron43210/HYPERSPECTRAL_DATA_DISTRIBUTED_SYSTEM", "tracker": "https://github.com/aaron43210/HYPERSPECTRAL_DATA_DISTRIBUTED_SYSTEM/issues", "author": "Aaron R", "tags": ["raster", "hyperspectral", "remote sensing", "spectral indices", "ndvi", "pca", "sam", "enmap", "openmp", "opencl"], "downloads": 1747, "latest_version": "1.0.1", "versions": [{"version": "1.0.1", "experimental": false, "qgis_min": "3.0.0", "qgis_max": "4.99.0", "downloads": 1675, "uploaded_by": "aaronr43210", "upload_datetime": "2026-10-18T00:55:15.314276"}, {"version": "1.0.0", "experimental": true, "qgis_min": "3.0.0", "qgis_max": "4.99.0", "downloads": 72, "uploaded_by": "aaronr43210", "upload_datetime": "2026-10-10T14:44:26.448690"}]}
