How fast will the archive be updated?
[top]
For Apparent green cover percentage optimized for arid regions (Desert Locust) and Small Water Bodies the archive will be updated every ten days: new products are calculated a few days after the past decade.
For NPP, NEP and DMP, the archive will be updated every ten days. At the beginning of the next decade, the products of the decade from 3 months ago are calculated.
What is the objective of Geosuccess?
[top]
The main objective of Geosuccess is to provide in near-real time operational services to the R&D community, and by doing so, to bridge the gap between scientists and end-users of higher level information on the environment.
Which type of products are demonstrated at the Geosuccess site?
[top]
Any operational product derived from earth observation data and giving information on the global environment, global change and the vegetation cover in specific, also including information and services in support of the management of treaty commitments. In this way, the Geosuccess server fully supports the GMES initiative.
Who developes the products?
[top]
Some products are developed inhouse while other come from associated institutes.
What is the role of Vito within the Geosuccess initiative?

What is the HDF format?
[top]
What is the HDF format?
The Hierarchical Data Format, or HDF, is a multi-object file format for sharing scientific data in a distributed environment. HDF was created at the National Centre for Supercomputing Applications (NCSA) to serve the needs of diverse groups of scientists working on projects in many fields. HDF was designed to address many requirements for storing scientific data, including:
- Support for the types of data and metadata commonly used by scientists.
- Efficient storage of and access to large data sets.
- Platform independence.
- Extensibility for future enhancements and compatibility with other standard formats.
HDF files are 'self-describing'. For each data object in and HDF file, there is information about the type of data, the amount of data, its dimensions, and its location in the file. Self-description means that many types of data can be included within an HDF file. For example, it is possible to have symbolic, numerical, and graphical data within one HDF file.
Where can I find the appropriate HDF software?
[top]
References on HDF information and software can be found at many places on the Internet. The site http://hdf.ncsa.uiuc.edu/tools.html gives a very good overview of software (also free software) that supports HDF formats.
