The Utilization of Standard Stratigraphic Division in Urban Operations in Changsha City
The standard stratum is generally classified based on urban survey data,supplemented by regional geological data and com-bined with local engineering construction experience,following the principles of"time-cause-engineering nature".Consequently,coding rules for the standard stratum are formulated.By using the standard stratum,through screening,digitization,induction and stratum registration,the survey data of Changsha urban area,which are uneven,ununified in standard and with a large time span,are integrated into a unified and standardized geological data,so as to realize information sharing and data reuse.The development of a comprehensive 3D geological model is to transform stagnant data into dynamic and actionable information,ultimately enhancing the efficiency of city operations.
