A common architecture for all Sentinel Toolboxes is being jointly developed by Brockmann Consult, SkyWatch and C-S called the Sentinel Application Platform (SNAP). The SNAP architecture is ideal for Earth Observation processing and analysis due to the following technological innovations: Extensibility, Portability, Modular Rich Client Platform, Generic EO Data Abstraction, Tiled Memory Management, and a Graph Processing Framework. Feature Highlights - Common architecture for all Toolboxes - Very fast image display and navigation even of giga-pixel images - Graph Processing Framework (GPF): for creating user-defined processing chains - Advanced layer management allows adding and manipulation of new overlays such as images of other bands, images from WMS servers or ESRI shapefiles - Rich region-of-interest definitions for statistics and various plots - Easy bitmask definition and overlay - Flexible band arithmetic using arbitrary mathematical expressions - Accurate reprojection and ortho-rectification to common map projections, - Geo-coding and rectification using ground control points - Automatic SRTM DEM download and tile selection - Product library for scanning and cataloguing large archives efficiently - Multithreading and Multi-core processor support - Integrated WorldWind visualisation
What's new in 14.0.0
New in SNAP 14.0 - Hyperspectral processing: new spectral-library with standard-format import/export, pixel-based spectral extraction, metadata editing, noise-reduction, resampling and classification capabilities. - Faster product reading: improved reader caching for NetCDF and Sentinel-3 products. - Updated reader infrastructure: broad reader updates, including improved virtual-file-system support. - Improved GDAL support: updated GDAL to version 3.12.1, with fixes for performance, memory usage and parallel processing. - Enhanced STAC support: better handling of product types and asset roles. - Better product compatibility: fixes for Sentinel-2, ENVISAT MERIS, NetCDF CF and EnMAP products. - Improved processing workflows: fixes for Graph Builder, DEM downloads, DIMAP export and mask propagation.
