Global Vegetation Monitoring Unit Insular Southeast Asia

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

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

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

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
