Land Use/Land Cover change in the Eastern of Thailand was explored which related with the characteristic of urban heat island by analyzing and estimating the visible and nearinfrared and thermal of Urban Heat Island (UHI) phenomenon that covered agricultural, industrial, and urban areas in the eastern region by using climate models in Geographic Information Systems (GIS) and RS (Remote Sensing) data. It integrated land surface temperature (LST) with estimated by single-channel algorithm for Landsat satellite data and ground-based weather stations in the years of 2006, 2011 and 2017. The eastern region of Thailand is the intensive industrial development region of the country, as a result, the region has developed and expanded into a city more than other regions. Land use is decreased in agriculture and forest and increasing of city/building all province in the region. Many of vacant land and agricultural land were replaced by roads, infrastructures, and buildings. There are many of urban communities and industries located spread throughout the region especially Chon Buri, Rayong, and Chachengsao provinces. Buildings and its surfaces and transport systems which constructed by brick, concrete and asphalt act as enormous heat storage. It accumulated the human and industrial activities of urban areas that had been caused urban zone to higher temperature than the surrounding countryside area. From the study, many cities in the region was significant increased in temperature.
