The PVA tool serves the highly interactive process of image and product inspection at EUMETSAT.

PVA

Since 2011 ask – Innovative Visualisierungslösungen GmbH develops the software solutions PVA and IPPS for EUMETSAT for the visualisation, analysis and presentation of satellite data and meteorological products.

The PVA (Product Visualisation and Analysis) Tool serves the highly interactive process of image and product inspection at EUMETSAT. It is used for quality control and analysis of current and archived satellite imagery and derived meteorological products.

It is also a core component of the IPPS, the Image Processing and Presentation Service, which provides fully automatic production of content for EUMETSAT’s image gallery from Meteosat, Metop and foreign meteorological data. The IPPS is operated 24/7 using the batch production system ProducerNG. PVA and IPPS are based on the solution platform TriVis Development Package (TriDev). TriDev and ProducerNG are both developed and owned by ask – Innovative  Visualisierungslösungen GmbH.

ACCURATE

Special care is taken for the accuracy of all computations in the domains of space, time and data values. Satellite “pixels” cover precisely defined
areas on earth which are well maintained in all map projections. Astronomical, physical and all other computations preserve highest data precision.

INTERACTIVE

PVA and IPPS feature the high performance that is required for interactive visual inspection and offer manifold tools for picking, filtering, creating histograms and scatter plots, and many more. This allows the data expert to quickly gain insight.

FLEXIBLE

The TriVis Development Package and all applications built on it like PVA and IPPS are structured in a strictly modular manner. The system’s behaviors is defined by a user-programmable processing lattice consisting of computation nodes and routes from input data to visual output display.

RELIABLE

Applications built on the TriVis Development Package are reliable and robust by design. The software architecture clearly separates layers and modules and interfaces to ensure this. In addition, the PVA and IPPS projects enforce extensive test plans.
