Analysis of Urban Survey Geological Data Governance
The development of urban geological informatization is relatively lagging behind other informatization,and the demand for his-torical geological data is increasing. Geological data is different from other methods such as surveying,construction,etc. It has the characteris-tics of long-term validity,high difficulty in collection,and difficult standardization. Therefore,the collection and management of historical geo-logical data are more important. Before geological informatization,urban survey data saved by urban construction archives and various urban survey units was a rare and indispensable source of data. This article explores the principles and methods of geological data governance in ur-ban surveying,as well as the application of geological data,through the study of standardization of urban engineering geological stratigraphic sequence,with the aim of serving as a reference for promoting urban geological informatization.
