Integration of GIS data into 3D space partitioning to enhance architectural modeling

This paper explores the integration of Geographic Information System (GIS) data within a 3D unbounded space partitioning framework to enrich architectural modeling beyond conventional practices. By investigating how built environment data can be incorporated into a topologically connected 3D model, the study aims to understand its potential impacts on the design and construction phases of a project, as well as the role that integration of adjacent outer space might have, departing from the building scale to parcels, cadastral, and city development plans in the future. Space partitioning, which divides the Euclidean space into distinct nonoverlapping domains, is explored for its potential to improve modeling accuracy and efficiency. By laying the groundwork for the embedding of comprehensive spatial relationships into the modeling framework, the paper seeks to stimulate discourse on the dynamic requirements of construction projects and the transformation of iterative architectural planning practices. It outlines terrain integration as the initial phase of this exploratory and investigative approach to incorporate various scales in 3D modeling for advancement within the Architectural Engineering and Construction (AEC) industry.
