This study aims to clarify the spatial composition and elements of traditional Korean Byeol-Seo Gardens through the field survey and the GIS analysis of topographical characteristics. The field research and survey were carried out on August and November in 2014 and November in 2015 at 9 gardens in Gwangju, Damyang region：MyunAngJeong, SongGangJeong, YeongGyeJeong, MoonIlJeong, KwanSooJeong, SikYoungJeong, HwanBuckDang, ChiGaJeong and MyuongOkHeon. Through creating the original contour maps by combining the field survey results with GIS data，the following aspects are consequently observed on the 9 gardens. (1) Byeol-Seo is considered to have spatial composition to be aware of the view from the Pavilion. (2) Topographical characteristics make spatial composition in Byeol-Seo and fall into two major categories. While prior researches focused on the meaning and philosophy of the gardens, this study, involving the quantitative analysis, elucidates the style of the spatial composition. This kind of analysis could be the basis of recognizing the morphological characteristics and the meaning of the spatial design of the traditional garden.
