Abstract
The development of an urban area has led to changes in land use which have an impact on the existence of green open spaces as one of the city's ecosystems to be less attention. Observation of green open space conditions by utilizing remote sensing technology is an important thing to do so that optimal development planning strategies can be carried out. This study aims to analyze the relationship between vegetation index values with vegetation density and to analyze the distribution characteristics of green open spaces in Denpasar City. The vegetation index transformation used is the Normalized Difference Vegetation Index (NDVI) and the Soil Adjusted Vegetation Index (SAVI). Linear regression analysis is used to determine the relationship between the vegetation index and vegetation density as a consideration in determining the availability of green open space. The results showed that the NDVI transformation produced a better correlation value (R2) of 0.842 compared to SAVI of 0.826. The results of the accuracy test of vegetation density mapping showed a level of accuracy of 90% and it was obtained that the green open space area reached 4,872.34 Ha or 38.92% of the area of Denpasar City. If this condition does not find a solution, it is feared that the availability of green open space will continue to decrease, so this research is important to do in order to provide information on existing green open spaces.
