“The Khorat Plateau is a plateau in the northeastern Thai region of Isan. The plateau forms a natural region, named after the short form of Nakhon Ratchasima, a historical barrier controlling access to and from the area. The average elevation is 200 m and it covers an area of about 155,000 km². The saucer-shaped plateau is divided by a range of hills called the Phu Phan Mountains.”

“The plateau tilts from its northwestern corner where it is about 213 metres above sea level to the southeast where the elevation is only about 62 metres. Except for a few hills in the northeastern corner, the region is primarily gently undulating land, most of it varying in elevation from 90 – 180 metres, tilting from the Phetchabun Mountains in the west down toward the Mekong River.”

“Khorat Thai, refers to an ethnic group named for their main settlement area in Khorat Plateau. Thai Khorat people have their own traditions and cultures called Khorat culture, which is similar to the culture of Thai people on the central plain, but their own unique words, dialect, costumes, songs, and beliefs are different from the rest of the Tai-speaking peoples.”
