ASSESSMENT OF THE LAND SURFACE TEMPERATURE DYNAMICS IN THE CITY OF SOFIA USING LANDSAT SATELLITE DATA
Journal Title: Aerospace Research in Bulgaria - Year 2017, Vol 29, Issue
Abstract
The article presents the first attempt to analyze the urban heat island of the city of Sofia using satellite data. For this purpose the thermal data from Landsat ETM+ and TIRS sensors have been used . A statistical analysis of the results was carried out as well as an analysis of the changes in the surface temperature for the selected time interval – 2000 – 2015 . The impact of the type of land cover was analyzed. For this purpose, a visual land -cover classification has been drawn up, whereby the surveyed territory is divided into 16 classes. A detailed analysis of the data over the entire survey period shows a gradual rise in the city's temperature due to the change in the urban environment. One of the conclusions of the study is that thermal images over time can be successfully used to detect changes in the land cover by temporal analysis.
