This paper aimed to study a basic approach of urban context variants for assessing the urban patterns and factors in spatial–dimensions of Chiang Mai using Remote Sensing data of Landsat–5 and Landsat–8 during the periods 2000–2015 Geo–Informatics and Space Technology Development Agency – GISTDA. This period is related with the city changed its policies and guidelines for economic development after the financial crisis and the new constitution in 1997. People are more involved in city development and government work. that is effect to the physical environment of Chiang Mai city has changed in many ways. As a result, this spatial analysis used the Object–based Classification approach of Landsat TM Image Resolution 30 meters, Band 7, 4, 3, with Geographic Information System (GIS) found that indicated the spatial pattern of urban growths by three periods: 1) during from 2000 to 2004 spread into the Western site, 2) from 2004 to 2010 spread into the Northern and the Southern site and 3) from 2009 to 2015 slowly increase in the Eastern site, which could be extracted by different attracting factors. Moreover, the observation and interviewing the samples who stayed inside the old center district are clarified for almost changed of patterns focused on living, environment, and the habitat as the dynamics of city. The old district context is transferred to newer trends of economic trading for tourism center without any conditions until Chiang Mai Comprehensive Plan 2012 and Chiang Mai Municipal Law 2014. The importance of dynamically tuned the land use tenure, the edge of center city, It extends beyond the physical, social or cultural boundaries. Recently, the human perceptions are isolated and separated each other from identity, structure, and meaning of Lanna as a major obstacle to cultural preservation and revitalization of the old district distinction in Chiang Mai. Their influence results could be further discussed within urban context variants that is should be specific planning system for policy–maker become a power to individual urban plan.
