From satellite imagery: U1 (urban index) and NDVI (normalized difference vegetation index) were calculated and used that information to construct urban density and vegetation distribution maps of the study area. Urban density and vegetation distribution were combined to estimate urban environmental condition; then compared to socioeconomic conditions. The results revealed that the Semarang Municipality had a higher percentage of developed or urbanized areas (49%) compared to the percentage of area covered by vegetation (42%). In general, southern Semarang had a higher quality urban environment and socioeconomic condition compared to northern Semarang, which had a higher urban density, lower quality urban environment and lower socioeconomic condition.
