the United States, is provided for demonstration purposes (Figure 10). An ASTER scene (Level 1B, path/row: 15/33), acquired on August 24 2003, was downloaded from GLCF (Global Land Cover Facility) website (http://glcf-umiacs.umd. edu/). TIR bands originally have 90 m resolution, so they were resampled using the nearest neighbor algorithm with spatial resolution of 15 m to make Sekil 10- Programin uygulamasinda kullanilan Baltimore ASTER goriintiisti them match to VNIR bands. The sample files used for demonstration are listed in Table 7. The ASTER imagery with 15 m spatial resolution and dimension of 5729 x 5124 was used as an example for LST retrieval in this study. The parameters for the ASTER imagery used during LST retrieval in the program are illustrated in Table 8.

The final LST distribution map of Baltimore, MD hat was calculated using atmospheric parameters was given in Figure 11. As illustrated in Figure 1, the minimum and maximum temperatures of he scene were computed as 278 K (4.85 °C) and 335 K (61.85 °C). Maximum temperatures were retrieved within dense urban areas while minimum emperatures were calculated in water and forested areas. Figure 11- Spatial distribution of the LST in the study area
