Abstract
In this study, a computer program, the Land Surface Temperature Calculator (LST Calculator) was developed in Visual Basic
.NET (2008) which employs the Radiative Transfer Equation (RTE) method. The LST Calculator is a valuable tool to study
thermal environments using the thermal band of Landsat TM/ETM+ data and make the land surface temperature retrieval much
simpler and faster. LST can be retrieved with this tool by inputting required parameters in the program. Thus, this program will
be helpful to those who are interested in studying thermal environment. A Landsat Enhanced Thematic Mapper Plus (ETM+)
image of Dallas – Fort Worth Metroplex was used as a case study for demonstration purposes.
