9 Global Vegetation Monitoring Unit GLC 2000 partners: Oceania ? Land cover: Min. Agr. & Forestry (New Zealand)

10 Global Vegetation Monitoring Unit GLC 2000: Insular Southeast Asia

11 Global Vegetation Monitoring Unit Insular Southeast Asia

12 Global Vegetation Monitoring Unit 10 - day mosaic of Insular Southeast Asia

13 Global Vegetation Monitoring Unit Generation of cloud-free mosaic  S1-images for the of full year 2000  2 year S10 images Approach I: S1-ProductsApproach II: S10 -Products  SWIR line error mask  Cloud haze threshold  Filter for angle Φ> 45º and hot spots (Φ,φ)  Water mask  Select max 15 percent of NDVI  Minimum in the red channel  SWIR line error threshold  Cloud-haze threshold  Cloud shadow-haze mask  Pixel selection by minimum in SWIR for monthly mosaics  Pixel selection by minimum in NIR from monthly mosaics

14 Global Vegetation Monitoring Unit Compositing results Approach I: Mosaic from S1 (daily) images Jan-Sep 2000 Approach II: Mosaic from 2 years S10 composites

15 Global Vegetation Monitoring Unit Land Cover Classes: Insular Southeast Asia Montane evergreen forest…………………………… Lowland evergreen forest…………………………… Thickets, shrubland, & cultivation of perennial…… crops Swamp evergreen forest……………………………. Mangrove (evergreen) forest………………………. Cropland……………………………………………… Burnt cover / Sparse or dry stages of …………….. vegetation Water………………………………………………….. 8 Land Cover Class P10 / P3 A3A10B2XXD1E1-P10 / A3A11B2XXD1E1-A12-P P9 / P8 A3A10B2XXD1E1-P9 / A3A11B2XXD1E1-A12-P / / 0003 A4A10B3XXD1E1 / A4A11B3XXD1E1 / A R1 / R1 A3A12B2C1-C4-R1 / A3A13B2C1D1E1-A14C4-R R3 / R3 A3A12B2C1D1E1-C5-R3 / A3A13B2C1D1E1-A14C5-R / 0006, A11 / A / / 0004(1)Z99] ??? A6A11 / A6A14 / [ A12Z99???? 8001, A1 LCCS Coding >>Mosaic class

16 Global Vegetation Monitoring Unit Present status of map

17 Global Vegetation Monitoring Unit Comments / Problems to be solved Splitting of mixed class ‘Thicket, shrubs, perennial cultivation’ into components: 1. Thicket/Shrub2. Perennial cultivations ( ongoing > IPB University Indonesia) Splitting of class ‘ burnt / sparse or dry vegetation’ into the 2 components partly possible with 2000 mosaic and elevation model ( ongoing > IPB University Indonesia) How to map burnt class? ‘burnt forests’– separation partly possible with external forest cover layer ‘burnt other vegetation’ How to code ‘burnt cover’ with LCCS? Closed forest cover recommended threshold: % as degraded forests are included
