Using Landsat TM thermal data to map micro-urban heat islands in Dallas, Texas

The purpose of this study was to determine the relationship between the absence of trees and the presence of micro-urban heat islands. The objectives were to determine the usefullness of Landsat TM bands 3 and 4 for tree cover mapping, and the uisefullness of TM band 6 in identifying micro-urban heat islands. All 7 bands were utilized in this study to provide the full spectral curve for differentiating all cover types. When micro-urban heat islands were determined and maopped in relation to tree cover, the final objective of this study was to conbine the informationn into a GIS to obtain a map or blueprint of the exact location of micro-urban heat islands in the Dallas area.
