Abstract

The invention provides an assembly type green building modeling method and an assembly type green building modeling system based on a GIS and a BIM. The assembly type green building modeling method comprises the following steps of: acquiring GIS data of a target place of an assembly type green building; processing the GIS data into a topographic map and a building element planar graph; constructing a BIM data model of the assembly type green building; and importing the BIM data model of the assembly type green building and a GIS three-dimensional model into GIS software to enable the same attribute data in the BIM data model and the GIS three-dimensional model to be associated in a one-to-one correspondence manner. According to the assembly type green building modeling method and the assembly type green building modeling system, the three-dimensional model of the assembly type green building can be automatically established by means of the GIS and the BIM, the BIM is combined for refined processing, the GIS is employed for three-dimensional visualization, and the assembly error is reduced, so that the correction workload of the assembly type part in the later period is avoided, thelabor time and the labor intensity of construction workers are reduced, and the benefits of an assembly type building enterprise are improved.

Description

technical field [0001] The invention relates to the technical field of modeling, in particular to a GIS and BIM-based prefabricated green building modeling method and system. Background technique [0002] Digital city represents the development direction of urban informatization and is an important means to promote the informatization of the whole country. Since entering the 21st century, digital city has developed rapidly and has become one of the most potential strategic high-tech fields. , in various application systems of digital cities, the 3D city model is gradually replacing the 2D city map, and has become an important tool in many fields such as urban planning, urban management, public safety, heritage protection, traffic navigation, tourism and vacation, military defense, film and television entertainment, etc. The expression form of basic geospatial information. [0003] Prefabricated buildings refer to structural housing buildings designed and built through on-si...
