About data and information
Is more data needed or have we reached information overload? • Is some important data/information missing or of too low accuracy?
Are current resources/information fully utilised and used efficiently?• Lack of data/information is not necessaryly the problem but their use and
application
Do we know where to find what information/data?• Users incl. decision makers are often not aware of existing information or do not
use it
How accessible is existing information really? In which way should information and data be made available?

European Commission (QLK5-CT-2002-30638) 2002-2005
The general objectives are maximising the value of existing data and databases by:
coordinating efforts to create forest information systems and services
supporting development of harmonised standards and procedures for data provision
increasing the usability of available data and databases
What is NEFIS?

Evaluation (WP5)
The evaluation addressed the following aspects:Metadata and metadata guidelines on their operability and applicability for
describing datasetsKeyword list and thesaurus (extra topic within the metadata evaluation)Data rights and data rights managementThe information needs and user’s expectations towards potential capabilities
of a NEFISThe extent to which NEFIS can serve as a harmonised electronic information
system for periodical data reporting/delivery to the Commission services,
national, pan-European and international organisations

Demonstration Package
The Demonstration Package consists of:Resource Discovery (RD) in which the proposed NEFIS metadata
schema is implementedNew Visualisation Toolkit (VTK) functionalities, including:
• support of spatial time series data;• tools for dynamic aggregation of grid (raster) data;• some new visualisation techniques
Data retrieval: Implementation of simple system for retrieval of data
from data tables from distributed and remote sites, collation of the data,
and processing into a format that can be used by the VTK
