    1. 1. Information server prototype for Global Forest Information Service (GFIS) JOINT FAO/ECE/ILO - COMMITTEE ON FOREST TECHNOLOGY, MANAGEMENT AND TRAINING Forestry Information Systems 2000 workshop, 16-20 May, Hyytiälä, Finland Jarmo Saarikko Finnish Forest Research Institute Metla, Risto Päivinen European Forest Institute, Tim Richards* Margherita Sini** [Space Applications Institute, Global Vegetation Monitoring Unit, European Joint Research Centre], m [email_address] *up to 20 April 2000, ** up to 15 June 2000
    2. 2. Global information needs <ul><ul><li>Increasing need for relevant up-to-date information on decision making dealing with forests </li></ul></ul><ul><ul><li>Countries with limited or slow access to latest scientific information on forests </li></ul></ul><ul><ul><li>Need to disseminate scientific information in these countries </li></ul></ul><ul><ul><li>Chapter 41, Agenda 21 </li></ul></ul><ul><ul><li>Intergovernmental Forum on Forests </li></ul></ul>
    3. 3. Common vision for GFIS <ul><ul><li>Intergovernmental approach </li></ul></ul><ul><ul><li>User orientation </li></ul></ul><ul><ul><li>Focus on countries with the greatest needs </li></ul></ul><ul><ul><ul><li>Specific target audiences </li></ul></ul></ul><ul><ul><li>Content – wide range </li></ul></ul><ul><ul><li>Catalogue approach </li></ul></ul><ul><ul><ul><li>no central collection of data </li></ul></ul></ul>
    4. 4. Use of Internet <ul><ul><li>WWW has affected the ways we work </li></ul></ul><ul><ul><li>Information access and exchange </li></ul></ul><ul><ul><li>From the global level to the local </li></ul></ul><ul><ul><li>The full impact on the way we work and on society is still unknown </li></ul></ul>
    5. 5. Advantages <ul><ul><li>Permanence of 24-hours per day </li></ul></ul><ul><ul><li>Immediacy of information discovery </li></ul></ul><ul><ul><li>Content diversity </li></ul></ul><ul><ul><li>Accessibility from almost anywhere </li></ul></ul><ul><ul><li>De-centralised approaches allowing content owners to maintain full rights </li></ul></ul><ul><ul><li>Value for money with low-cost solutions </li></ul></ul>
    6. 6. General search engines <ul><ul><li>No more able to cover the whole net </li></ul></ul><ul><ul><li>The next generation of search tools will contain more specialised and targeted services, </li></ul></ul><ul><ul><li>More and more services will be provided to registered clients </li></ul></ul><ul><ul><li>User interfaces can be modified according to personal requirements </li></ul></ul>
    7. 7. Low search engine coverage <ul><li>a Coverage with respect to the combined coverage of all engines; b Coverage with respect to the estimated size of the web. </li></ul><ul><li>Relative coverage. 1,050 queries used, 25–28 February 1999. These estimates are of relative coverage for real queries, which may differ from the number of pages actually indexed because of different indexing and retrieval techniques. </li></ul><ul><li>[ Lawrence & Giles 1999 |NATURE|VOL 400|8 JULY 1999|Fig 2|page 108|] </li></ul>
    8. 8. Providers compete for users <ul><ul><li>One user usually cannot effectively use but a few different services </li></ul></ul><ul><ul><li>Most services on the internet have been free, their funding is often based on advertising </li></ul></ul><ul><ul><li>Research information in forestry is often non-competetive </li></ul></ul><ul><ul><li>However, if the target audience is the general public the information producer enters the same competitive field as described above </li></ul></ul>
    9. 9. GFIS structure <ul><li>1. Information Server </li></ul><ul><li>2. Locator </li></ul><ul><li>3. Metadata </li></ul><ul><li>4.
