GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Contributing Institutions

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Logistical Approach 1/. Centralised processing 2/. First-pass class labels 3/. Regional expert assessment of classes – re-labeling 4/. Class rationalisation 5/. Integration of specialist areas for regional product

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March /. Centralised processing –the data set Creation of seasonal mosaics from S10 product Jan-Mar Apr-Jun July-Sept Oct-Dec Cloud Screening Image selection on lowest SWIR

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Combining of VGT seasonal images Masking of evergreen forest (use of TREES 2000) Unsupervised clustering to 50 classes

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March /. First pass class labeling -Semi- evergreen forest -Dry forest -Shrubs (dense / sparse) -Savannah with shrubs -Savannah -Sparse grasslands -Agriculture -Barren

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Class labeling -Spectral signature -Texture and context -NDVI profile -Existing land cover maps and ancillary data

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Major Problems Cloud shadow in forest areas and Andes Seasonal aspects not directly related to the land cover – snow / flooding / burning Main spectral ambiguity – grasslands / agriculture Urban areas not easy to descriminate

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Main problem areas – V1.1 NE Brazil Caatingas Andes transect Southern Brazil Argentina from Monte to Steppe Magellan grasslands

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Venezuela Brazil Southern Cone Amazon forest 3/. Regional Experts working on data

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Regional Experts helping with validation

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March /. Integration of specialist areas for regional product Whilst all of South America is completed to the mimimum GLC 2000 legend – some areas/land cover types will have more detailed products -NE Brazil -Swamp forests (JERS-1 data) -Bamboo dominated forests (Acre / Peru)

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Class rationalisation with other tropical regions

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Intercontinental comparisons of vegetation dynamic from NDVI- derived parameters for each map class -maximum NDVI -adjusted minimum NDVI -range of NDVI -rates of change of NDVI -integrated NDVI -parameters of seasonality (fit of seasonally adjusted curves)

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 NDVI maximum monthly image – allowing intercontinental comparisons

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March NE Brazil should be ratified with EMBRAPA by the end of March - A final “draft” for July / August -first draft map has been created -Errors due to spectral confusion -Lack of adequate knowledge of certain cover types Current Status

GLC 2000 – “FIRST RESULTS” WORKSHOP JRC – Ispra, March 2002 Final Comment Importance of the Global Legend Importance of the Regional Legends and the partnerships with national experts worldwide
