Abstract

This research aimed to develop the district unit plan simulation using procedural modeling based on shape grammar. For this, Esri's CityEngine 2020.0 was selected as a main development tool, and Inside Commercial Area in Bangi-dong, Songpa-gu, Seoul as the research site where about 25% of the total area was developed over the past five years. Specifically, the research developed the simulation through the following three phases of Data-Information-Knowledge after selecting necessary parameters. In the Data phase, 2 and 3 dimensional data were obtained by utilizing data sharing platforms. In the next Information phase, the acquired data were generated into various procedural models according to the shape grammar, and the 2D and 3D layers were then integrated using relevant applications. In the final Knowledge phase, three-dimensional spatial analysis and storytelling contents were produced based on the integrated layer. As a result, the research suggests the following three implications for the simulation development. First, data accuracy and improvement of sharing platforms are needed in order to effectively carry out the simulation development. Second, the guidelines for district unit plans could be utilized and developed into shape grammar for procedural modeling. Third, procedural modeling is expected to be used as an alternative tool for communication and information delivery.

본 연구는 2차원 도면 표기의 본질적 한계가 지적되는 지구단위계획의 수립지침 중에서 '건폐율·용적률·높이 등 건축물의 규모'에 대해 절차적 모델링을 활용하여 3차원 지구단위계획의 시뮬레이션을 개발하였다. 이를 위한 개발의 도구로 에스리(Esri)사의 시티엔진(CityEngine 2020.0), 아크GIS 프로(ArcGIS Pro 2.6.2), 웹 씬(Web Scene)을 활용하였으며, 연구대상지로 최근 5년간 필지의 약 25%가 개발된 송파구 이면부 상업지역을 선정하였다. 본격적인 시뮬레이션 개발을 위해, 파라미터를 선정한 이후 자료(Data)-정보(Information)-지식(Knowledge)의 3단계 과정에 따라 개발을 진행하였다. 본 연구는 시뮬레이션 개발 과정에서 다음의 단계별 결과물을 생성하였다. 우선 자료(Data) 단계에서 공공 및 민간 데이터 공유 플랫폼을 활용하여 2·3차원 자료를 획득하여 구축하였다. 다음 정보(Information) 단계에서 구축한 자료를 형상문법에 따라 다양한 절차적 모델들을 생성하였으며, 이후 애플리케이션을 활용해 레이어를 통합하였다. 마지막 지식(Knowledge) 단계에서 통합된 레이어를 활용하여 3차원 공간분석 및 스토리텔링 컨텐츠를 생산하였다. 결과적으로 본 연구는 다음의 세 가지 단계별 시사점을 제시한다. 첫째, 개발에 필요한 자료 정확도의 향상 및 공유 플랫폼 개선 등 절차적 모델 개발을 위한 환경 개선의 필요하다. 둘째, 지구단위계획 수립지침은 공간적 특성을 제도적으로 규정한 지침이기 때문에 형상문법 스크립트로 개발되기 용이하다. 셋째, 절차적 모델링은 지구단위계획 작성 과정에서 심의, 자문, 주민 의견 수렴 등 의사소통 및 정보전달의 대안적 도구로 활용 기대효과가 크다.
