Figure 4. Four LANDSAT 8 snapshots acquired on 25 June 2013 over Riau revealing areas that have been recently burned (dark purple areas). Smoke plumes, indicating active fires, can still be seen in the snapshots to the left. The rectangular features of the burned areas, located in the middle of plantations (grid-like and rectangular patterns), suggest that these fires have been lit as part of the management of existing plantations.
