Abstract
With the continuous advancement of urbanization,surveying and mapping geographic information data,which possess unified spatial benchmarks,multi-source integration,and high timeliness,play a fundamental supporting role in the construction of smart cities.This article,based on various practical cases and using a comparative analysis method,reveals the logic,scenarios,and differentiated paths of how surveying and mapping geographic information data empower smart city construction.In response to current challenges such as data sharing barriers,insufficient update timeliness,and shallow integration with business operations,it proposes optimization paths including the construction of a standardized data sharing system,the establishment of an integrated dynamic update mechanism of'space-air-ground-network',deeper integration of cutting-edge technologies,and the improvement of full-cycle data security protection,aiming to comprehensively enhance the supporting capabilities of surveying and mapping geographic information data in smart city construction,and provide reference for its deep integration into smart city development,contributing to urban high-quality development and modernization of governance capabilities.关键词
