ABSTRACT:
Urban
environment has functioned not only for ecological reason but also for
socioeconomic function, due to this reason extraction of urban vegetation in
highly dense urban environment becomes more important to understand the inhabitants’ satisfaction of urban green
space. With a medium resolution of satellite imagery, the precision is very low. We used high resolution of WorldView-2
satellite to raise the accuracy. We chose Depok City in West Java as a case
study area, analyse four multispectral bands, and apply TCT algorithm for
getting vegetation density. The relationship between vegetation density and
inhabitants’ satisfaction was calculated by Geo-statistical technique based on administrative
boundary. We extracted three types of urban vegetation density: good, mid and
low. The final result shows that the inhabitants are mostly satisfied with good
density of urban vegetation in the city forest inside Campus University of
Indonesia.
