Research On Data Integration Technology For Digital Geological Survey

The digital geological survey involves various aspects of geosciences.The level of its research is not only an important indicator of the level of geological work and geological technology,but also an important factor in the country’s geological work capacity to serve economic development.The application of digital geological survey software has brought a lot of convenience to geological survey work,and data integration in geological survey software is a rather thorny issue.This article starts from the perspective of data integration technology for digital geological surveys.Through the actual investigation of the needs of geological surveyors,through the analysis of geological survey contents of different topics.And systematically analyzed and studied the design principles,construction methods,and data table structures of reusable dynamic form construction technologies.On this basis,a method for integrating geological survey data between different topics is realized.Through the study of the data conversion format of mainstream geological surveys,a simple element library using a common data conversion tool was identified.Using the design file conversion interface middleware,the integration and import of data in different formats of the universal geological survey software are realized.At the same time,a GEX exchange file format was designed to export the digital geological survey’s internal encrypted file in the form of a plaintext file.Achieved the external release of the internal data of the digital geological survey,making it possible for geological surveyors using different software to exchange and share data.Through the study of two-dimensional mineral data collection,the gridding methods of Inverse Distance Weighted(IDW),Inverse Distance Weighted Modified Quadratic Shepard(IDWMQS)and Kriging were implemented.2D data integration for DTM/DEM 3D data,enabling two-dimensional data integration for mineral forecasting.The DTM/DEM data management was implemented through data sets,which provided the data foundation for mineral forecasting in the geological survey field.
