Precise Mapping of Urban Population Base under the Influence of Digital Twin Technology:Innovative Technological Framework and Prospects for Planning Application
Digital twin is one of the fundamental technologies for achieving intelli-gent spatial planning.Unlike traditional engineering twin technologies,urban digital twins have not achieved sufficient mapping accuracy over a long period of time due to complex population dynamics and social changes,especially fluctuations in popula-tion statistics.This limitation has made it difficult for existing digital twin technolo-gies to provide precise population databases necessary for effective planning decision-making.This paper reviews the technical challenges of urban digital twins and exam-ines current mainstream population data mapping methods and their shortcomings.It proposes an innovative technological framework for accurately mapping urban popula-tions based on the principles of"real space,real population,and real demand".This framework integrates extensive data from various government sources to establish a comprehensive digital population base through data engineering.The framework en-ables fine-grained multidimensional analysis of urban population,accurate provision of community facilities,and improved quality of territorial spatial planning.
