A STEP BEYOND VISUALIZATION: HOW TO INGEST METEOSAT SECOND GENERATION SATELLITE DATA AND PRODUCTS INTO McIDAS-V, ILWIS AND TerraMA 2

The Laboratory for Analyzing and Processing Satellite Images (LAPIS) of the University of Alagoas (UFAL) has been very active in the usage of Meteosat Second Generation (MSG) satellite data and products since 2007. These data and products are received in near-real time using simple and low cost ground reception infrastructure. Several examples of the ingest and display process for MSG satellite data and products are presented. The ingest of these satellite data and products is accomplished using a McIDAS-V, ILWIS and TerraMA 2 tools. It is also shown how these MSG satellite-based products can be combined with other data. Results show that McIDAS-V, ILWIS and TerraMA 2 are very useful tools to researchers and forecasters in the input and display process for MSG satellite data and products.


Introduction
With the drastic advances in technology over the past decades, the availability, as well as the quantity, of large data sets for research in almost every scientific field has increased dramatically (e.g. Kehrer, 2011;Nocke et al. 2008). More specifically, the availability of earth observation-based The additional importance of GEONETCast systems is that they provide the measurements, and products for validating the prediction methodology (non-real-time), and for verifying the forecasts (near-real-time), including both the guidance, and the actual forecasts and warnings .
Observations from satellites are now providing quantitative information about how the Earth system varies on a variety of spatial and temporal time scales, documenting longerterm evolution, and providing information that can inform prediction and enable better policy and management decisions (Barbosa and Kumar, 2012 In other words, visualization is concern to generate static images that can represent geostationary satellite data. Furthermore, going beyond the visualization analysis, complex data manipulation requires solutions "out-of-core" including hardware and software techniques (Nocke et al. 2008

Requirements for MSG Satellite Data
MSG satellite data and products are distributed to the user mainly through the

Formats
To carry the development of the ingest and display process for MSG satellite data and products, a simple set of requirements are formulated. The requirements for these data and products are: i) Setting up geographic data; ii) Conversion of data and products into McIDAS-V, ILWIS, and TerraMA 2 tools compatible format; iii) Automatic ingest of data and products into these tool database via low cost ground reception infrastructure; iv) Ability to display these data and products in a meaningful way (readout, display, integration these data and products with other data available in EUMETCast).

Product Extraction Facility (MPEF)
The MPEF parts of the MSG Ground  Normalized Difference Vegetation Index (NDVI) (Barbosa, 2006) Product that is part of the processing of the analysis of scenes based on visible and near infrared reflectance of VIS 0.6μm and 0.8μm channels, displaying information on land cover and its seasonal variation.

Analisys Satellite Application Facility (LSA SAF)
The LSA SAF  In ILWIS was used plugin Geonetcast Toolbox for processing. It allows direct import of data EUMETCast system and processes those using ILWIS or other systems for geospatial analysis (Figure 3). To use the graphical interface, the settings can be made from an input directory, another departure and date of data to be processed.

Results and discussion
The ingest of MSG satellite data and products from LAPIS from direct EUMETCast

FVC and MPE products
The sensitivity of TerraMA 2 to the ingestion of FVC (Fraction Vegetation Cover) and MPE products is displayed. Figure 10 shows FVC and MPE products are geographically overlapped to generate a spatial pattern that allows for identifying the differences in vegetation and rainfall outputs.
The FVC product is the one biophysical parameter that determines the contribution partitioning between bare soil and vegetation  Overall, the FVC product is able to be ingested into TerraMA 2 over the municipalities analysed.  The requirements for these data and products were: i) Setting up geographic data; ii)

Conversion of data and products into
McIDAS-V, ILWIS, and TerraMA 2 tools compatible format; iii) Automatic ingest of data and products into these tool database via low cost ground reception infrastructure; iv) Ability to display these data and products in a meaningful way (readout, display, integration these data and products with other data available in EUMETCast).
Therefore McIDAS-V, ILWIS and TerraMA 2 are very useful tools to researchers and forecasters in the input and display process for MSG satellite data and products from direct EUMETCast readout system. .
