This paper presents the results of an assessment of change in urban green spaces in Thanh Hoacity (Vietnam). Sentinel 2 MSI data in 2015 and 2021 are used to calculate 3 parameters: percentage ofgreen, weight of green types, and weight of proximity to green. These parameters are used to calculate theWeighted Urban Green Space Index (WUGSI). The final result shows the distribution of green space inthe study area consisted of very high-quality green, high-quality green, moderate quality green, and lowquality green. The obtained results show that the quality of urban green space in Thanh Hoa city haschanged significantly in the period 2015-2021, in which the area with category “low quality green space”increased from 7.17% up to 9.48%; areas with category “very high-quality green space” reduced from65.02% to 47.39%.
