Abstract

Green open space plays a crucial role in maintaining ecological balance and quality of the urban environment. However, urban development has resulted a decline in green open space. The dynamics of green open space distribution due to rapid urbanization are often difficult to monitor effectively. Based on this, utilization of remote sensing is considered to facilitate effective and efficient monitoring of green open space areas. This study aims to identify and analyze the dynamics of green open space distribution in the urban area of Padang using Planetscope imagery. The methods used in this study include Planetscope image processing with spectral transformation techniques and multispectral classification as well as GIS-based spatial analysis. The analysis was conducted with a multitemporal approach to detect changes in the area and distribution of green open spaces over several time periods. Validation of the data analysis results was carried out by comparing the classification results with field reference data. The expected results of this study are geospatial visualization of the distribution of green open spaces in the urban area of Padang and an analysis of changes that have occurred in recent years. Therefore, outlook with the results of the study can contribute to the monitoring and management of green open spaces in the urban area of Padang more accurately and sustainably. The results of this study can also provide a reference in spatial planning and urban environmental conservation efforts in order to realize the Sustainable Development Goals (SDGs), especially point 11 sustainable cities and communities.
