GLC2000 First Results Workshop

Ispra 18th to 22nd March 2002

Project overview


Review of glc 2000 objectives
Review of GLC 2000 objectives

  • Provide Global Land Cover for 2000

  • Serve a broad user community

    • Science programmes (IGBP,…)

    • Global Observing Systems (GOFC – GOLD)

    • Environmental Conventions (MA, IPCC)

    • UN Organisations (UNEP, FAO, UNFF)

    • Regional development assistance programmes

    • National needs


Implementation strategy
Implementation strategy

  • VEGA 2000

    • VEGETATION data are a sound base for land cover mapping

    • Centralised processing ensures consistency of basic data across regions

    • provides observations throughout year 2000

  • Scaleable legend

    • Regionally detailed & globally applicable through aggregation

    • LCCS ensures traceability between the two


Implementation strategy cont
Implementation strategy cont.

  • Implementation by regional experts

    • optimises image classification methods

    • supports regionally appropriate map legend definition

    • validation by regional experts

    • international ownership

    • spreads the workload


Glc 2000 project status
GLC 2000 Project Status

  • The VEGA 2000 S1 data set covers the period 1st November 1999 to 31st December 2000

  • 55 regional windows have been extracted and distributed by GVM to 30 GLC 2000 partners

  • The Global legend has been agreed upon

  • A range of methods have been used to generate first-draft data classifications for regions including Eurasia, Africa, South America, North America, SE Asia and Europe


Workshop objectives
Workshop objectives

  • Review GLC2000 production status

  • Review image classification methods

  • Review global and regional legends

  • Review database design & implementation

  • Review product validation strategy

  • Review product distribution / publication policy


Validation strategy
Validation strategy

  • Regional responsibility for regional products

    • Everyone can go as far as they want

    • A “uniform” systematic QA adopted by all

  • Global product

    • Single approach to give statistically valid measures of global product’s performance

    • International involvement and consensus

    • Special side session on Wednesday morning


Product distribution publication policy
Product distribution / publication policy

  • Regional maps should be published by the lead scientists and their teams

  • Regional databases (maps, supporting metadata) will be collected by GVM, aggregated to give the global product and made available to all partners + the wider community via Web

    • All partners fully acknowledged

    • Mirror sites established within the Partnership


Continued
continued…

  • Published workshop report based on a written version of the presentations. All submissions by 10th May

  • GVM to co-ordinate production of GLC GBA 2000 Atlas

    • Project summary

    • List of partners

    • Region by region description of map legend

    • classification method summary

    • the regional map (at reduced scale)

    • full scale sub-sets to illustrate the thematic / spatial detail of the product and to illustrate applications…focus is on processes with high regional relevance

  • CD ROM Version of the Atlas


Workshop regional group objectives
Workshop regional group objectives

  • Harmonize regional products

    • Compare map outputs within regions (Class boundaries, area covered)

    • Finalise regional map legends

    • Finalise regional aggregations to the global product legend

  • Regional product quality assessment

    • Structured validation process to be tested at the workshop


Summary
Summary

  • Agreement on regional legends

  • Agreement on a final QA strategy

  • Agreement on Global Validation strategy

  • Identify all remaining gaps

  • Agree on a product and publication strategy

  • Agree on data format and metadata structure

  • Finalise the remainder of the project calendar
