SNAP Toolboxes by esa-European Space Agency

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
