The results showed that in 2006 the GOS in Depok city was 2.359,20 ha and 1.729,53 ha in 2011 or it was a decline at about 629,67 ha during the period. Based on population number, Depok required 3.627,23 ha of GOS. Scalogram analysis indicated an increase in hierarchy of some subdistricts to level II and level I, and reducing of level III.
