Monitoring of Radiant Temperature Distribution of Urban Vegetation Using High Resolution Multi-temporal Remote Sensing Data

摘要

[ABSTRACT] In most studies concerning the basic analysis of spectral reflectance of vegetation surface, only visible, near infrared, and middle infrared images from satellite views, i.e., LANDSAT, SPOT, etc., are analyzed. Thermal infrared images, though, should also be used to indicate the characteristics of its radiant temperature distribution of urban vegetation, from the point of the deterioration of the urban thermal environment. This paper describes the results of the analysis using high resolution images of multi-temporal airborne multi-spectral scanner (MSS) data. The relationship between the radiant temperature distribution of urban vegetation and the area of each group of vegetation is investigated, considering weather parameters, i.e., incident solar radiation and air temperature. Furthermore, the relationship between the normalized vegetation index (NVI) and the temperature of urban vegetation is indicated.
