Research On Data Management Technology Of Surveying For Completion Of Construction Project Planning

With the continuous advancement of urban construction,the number of completed construction projects is increasing year by year,and the planned completion survey data is also increasing.As one of the most important contents of urban construction,how to store and manage the historical data effectively and provide basic data for future urban construction has become an urgent problem to be solved.Based on the background of "multi-measurement in one" era,combined with the actual production work of planned completion survey,and on the basis of fully understanding the planned completion survey of construction projects,and supported by the planned completion survey data of construction projects of production units,this paper studies the data processing method and data management technology of planned completion survey of urban construction projects.The integration and fast processing of historical data are discussed in this paper:(1)According to the analysis of the basic components of the survey data of construction project planning completion,the characteristics of the data are analyzed,and then the classification principles and methods of the data are deeply studied and established.On the basis of the data classification,the basic framework system of the survey data of planning completion is established,so as to realize the effective integration of the complicated historical data.(2)On the basis of exploring the principle of data processing,this paper studies the technology and method of using GIS technology to process the historical data of planning and completion surveys,and creates an automatic data processing model based on ModelBuilder in ArcGIS,which integrates data format conversion,element type conversion and projection coordinate system conversion in data processing methods into a workflow,which to reduce the repetitive operation in the process of data processing and improve the automatic processing speed of historical data of planned completion survey.(3)Taking the historical data of planned completion survey of a production unit as an example,the data integration problems and corresponding solutions caused by various data formats and complex structures in the process of data integration are studied.At the same time,the designed automatic data processing model is applied to the practice of production projects,which speeds up the data processing speed and improves the production efficiency of production units.Based on the specific production practice,this paper studies and analyses the historical data of planned completion survey,establishes the data framework of planned completion survey,and establishes a complete set of process of data storage.Through continuous summary and exploration in practice,and further innovation and improvement on the basis of original processing,an automatic data processing tool based on Model Builder is designed and applied to process the planned completion survey data,which ensures the complete and accurate storage of historical data,improves the work efficiency of production units and promotes multimeasurement.The smooth implementation of "Unity" has important practical significance.
