Abstract:
The research was the application of remote sensing and geographic information
systems for estimation of the land surface temperature, which analysis by used a split-window
method for LANDSAT-8 OLI and TIRS and created automatic toolbox in ArcGIS. This research
was also an of land use, by studies correlation between land surface temperature and five types of
land use consisting Forests, Agricultural land, Water bodies, Urban and building lands and
miscellaneous land. It also studied the urban heat island phenomenon by the Urban thermal filed
variance index.
The result found Rayong average temperature was 30.12 degrees Celsius and land use
found most areas of the province remains an agricultural area, which was 1,546,456.25 Rai or
69.66 % of the total area. Forests was 178,787.50 Rai or 8.05%. Urban and building lands
254,131.25 Rai or 11.45 %. The overall accuracy assessment of land use was 85.60%. The study
analyzed the statistics land surface temperature in each district, shown that Amphoe Mueang
Rayong, Amphoe Nikhom Phatthana, Amphoe Ban had higher average temperature because land
covers mostly was urban and building, field crop and miscellaneous. However, Amphoe Khao
Chamao, Amphoe Ban Khai and Amphoe Wang Chan had lower average temperature because
land covers mostly was forests, Perennial trees/Fruit trees. The results was consistent with the
analysis of the correlation between land surface temperature and land use. The increasing of
urban and building area effected to higher temperature. In the contrast, increasing of forest area
effected to lower temperature. Both R correlation was 0.8317, -0.7418 respectively (the level of
significance 0.05). In addition, most areas of Rayong have not been affected from the urban heat
island phenomenon, but the temperature is a factor to increase urban heat island phenomenon.
