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
