EFIS functionality• Catalogue function; node of GFIS.
– Searchable register of Forest Inf. Objects.– DC, XML, WS OK
• Distributed Database (ddb)– Interoperable data access…
• WS Federation, Grids, etc– …of mutually compatible and comparable
data– …for processing, analysis and decision
support• Agregation,• Comparision,• Modelling and Forecasting.
PROBLEM 1• The data in national databases (i.e. Forest
Inventories) are NOT consistent or compatable.– Forest area; dbh; volume-to; productivity class….
• Well known to EFICS (89, 97) which looked at :– Harmonisation
• (adoption of common standards - very expensive)
– Standardisation • (adjustment/scaling of data to compatibility – not easy)
• CONCLUSION: Data-access interoperability is not enough, by itself.
SOLUTION
• Standardisation models required to:– Convert National inventory data to a common flexible
STANDARD– Convert between different National standards
• Empirical Data is required.– Too expensive?– Use of Heuristic Modelling Patches in NEFIS
demonstrator? (From EFICS data???)
• Need a Standards Conversion Toolkit (SCTK)
PROBLEM 2
• All the national databases have different base-dates.
• Hence,
the national databases are base-date inconsistent.
SOLUTION?
• National Inventory up-dating models are needed.
• Equivalent to Inventory-based forecasting models.
• Forest Inventory Forecasting Toolkit?
• Not Easy!!!• Expensive!• Localised or Centralised?
PROBLEM 3
• Where do the standardisation and up-dating processes fit within the EFIS++ ddb interoperability middleware?
SOLUTION(S)• In the central EFIS ++ processing engine?
– Possible.– This may be complicated, and very slow.
• Possible alternative solution:Construct a centralised standardised and updated Data Warehouse of European Forest Inventories.– Re-freshed only periodically– High quality– Fast access– Easy to analyse, model and mine.

Where Now for WP3?
• Progress the population of the NEFIS KB• Progress the analysis/understanding of
European forest information processes, requirements and actors through Use Cases.
• Progress the analysis of a European Forest Information System for Decision Support through UML.
• Closer integration with WP2.
