The objective of this research is to compare spatio-temporal data for studying land use (LU) change and diversity in 3 scales of the classification system of Land Development Department (LDD) in the area of Nakhonratchasima city municipality (NCM), Muang district (MD) and Nakhonratchasima province (NKP) between 2007 and 2019. This study used LU data in the years 2007, 2011, 2015, and 2019. The boundary of the municipality, district, and province were in the form of a geographical information system (GIS) to analyze-based spatial analysis tools in the ArcGIS program. The results are found that LU diversities in levels 1 and 2 are not different from each other, but level 3 has an obvious difference as NCM 33 types, MD 64 types, and NKP 138 types. Inversely, LU changes in levels 1, 2 and 3 are distinct. At level 1, the urban and built-up land in NCM is increased by 1.219 sq.km. (3.226 %), while the agricultural land in MD and miscellaneous areas in NKP are decreased by 112.056 sq.km. (14.683 %), and 584.114 sq.km. (2.818 %), respectively. In part of level 2, the city, town, and commercial land in NCM, the rangeland in MD, and the rice paddy land in NKP are increased by 0.619 sq.km. (1.639 %), 42.527 sq.km. (5.572 %), and 1,524.802 sq.km. (7.356 %), respectively. Lastly, in part of level 3, the city, town, and commercial land in NCM, and of rice paddy land in NKP are increased by 0.619 sq.km. (1.639 %), and 1,503.579 sq.km. (7.253 %), respectively, but the cassava land in MD is decreased by 112.535 sq.km. (14.746 %).
