Urban Axis and City shape evaluation through spatial configuration in ‘Lan Na’ Northern Thailand Historic city

Abstract

Abstract This paper revealed urban axis and city shape identity that influenced by its concepts and present activities issues in ‘Lan Na’ historic cities in northern Thailand. This study using space syntax technic called axial line analysis combined with GIS analysis, to examines how history geo-politic issues have influenced to its urban axis and network. Results show urban axis has highly coexisted with its city shape determined through high integrated axial lines. This city shape was, however, defined by its establishment concepts as ‘Sankh’, ‘Traiphum’ and freeform. Different shapes of urban axis have been determined by these concepts. As well as the largest public space in some ‘Lan Na’ historic cities, it directly attaches to high integrate lines that represent as urban axis core. However, depending on gradually develop influences, the function of public space in urban axis core has various types. Mostly, these spaces, have related to Buddhism religious usage or colonialism spaces. Settlement pattern using kernel analysis revealed that residents in every city settled in a tranquil area determined by space syntax. Additionally, settlement clusters adjacent to urban axis or high activities traffic. In summary, from reviewed historic cities in ‘Lan Na’, it found that this urban axis could be identified using multi-method. To enhance urban axis in historic cities, both object and subject aspect had to be revealed to apply as delicate historic conservation measures.
