Analysis of Urban Heat Environment by Utilizing Fine Land Cover Information

Abstract

The higher-resolution satellite image provides us finer land cover information than ever. This study firstly concerned the relationship between land covers and brightness temperature. It was investigated through the analyzation of the urban heat environment mechanism utilizing the information from the higher-resolution satellite (IKONOS). Secondly, quantity, quality, and space of greenery were studied, for greenery has a strong causal relationship with heat environment. In conclusion, greenery are highlyimportant in order to prevent heat environment in urban areas. Also, utilizing the higher-resolution satellite image to analyze urban heat environment was proved as one of the valuable method by this study.
