Scope
Main technical content: This document specifies the basic requirements, data preparation, model construction, model simplification, quality inspection, data update, and result compilation related to the processing of digital twin data for urban housing buildings. (1) Definitions and explanations of related terms for the processing of digital twin data for housing buildings are provided. (2) The temporal and spatial reference systems, work area division, model unit grading, data formats, metadata requirements, processing flow, and safety requirements involved in the processing of digital twin data for housing buildings are standardized. (3) The types of data and source data requirements involved in the processing of digital twin data for housing buildings are proposed. (4) The construction of digital twin models for housing buildings is divided into several stages: geometric information processing, attribute information processing, relationship information processing, business information processing, and numerical-geometric integration. The work content and methods for each stage are standardized. (5) Simplification methods for digital twin models of housing buildings are proposed. The simplification of models is standardized from two dimensions: data reduction and lightweight processing.
