12. 10 - day mosaic of Insular Southeast Asia

13. Generation of cloud-free mosaic • S1-images for the of full year 2000 Approach I: S1-Products Approach II: S10 -Products • 2 year S10 images 1998-2000 • SWIR line error mask • Cloud haze threshold • Filter for angle Φ> 45º and hot spots (Φ,φ) • Water mask • 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 • Select max 15 percent of NDVI • Minimum in the red channel

14. Compositing results Approach I: Mosaic from S1 (daily) images Jan-Sep 2000 Approach II: Mosaic from 2 years S10 composites 1998-2000

16. Present status of map

17. Comments / Problems to be solved • Closed forest cover recommended threshold: 40-100% • as degraded forests are included • Splitting of mixed class‘Thicket, shrubs, perennial cultivation’ • into components: 1. Thicket/Shrub 2. 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?
