Comments / Problems to be solved
• 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?
• Closed forest cover recommended threshold: 40-100%as degraded forests are included
