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
