Abstract
This study aims to determine: (1) spatial-temporal variations in land surface temperature in Medan City, (2) spatial-temporal variations in vegetation index values (NDVI) in Medan City, (3) the relationship between LST and NDVI in Medan City. The design of this research is correlational and population research conducted with a spatial and temporal approach to analyse data spatially in different years of image recording. The variables in this study are land surface temperature and vegetation density. Data collection is done by image interpretation, observation, and documentation methods — data analysis techniques in image interpretation in the form of image transformation LST, NDVI, and spatial statistics. The results showed that the lowest land surface temperature of Medan City in 2011 was 20.72o C and the highest was 31.82o C with an average temperature of 26.05o C. The lowest temperature found in Medan Labuhan, and the highest temperature found in Medan Denai. For 2018 shows the lowest temperature is 19.32o C in Medan Belawan Sub-district, while the highest temperature is 34.43o C in Medan Denai Sub-district. The average temperature for 2018 is 28.1o C. Accuracy test shows there is a strong relationship between LST and temperature measurement. NDVI transformation results show that in 2011 the vegetation density of Medan City was dominated by medium density classes and in 2018 dominated by low-density class. This result shows a decrease in the level of vegetation density in Medan City.
