Research On Online Interactive Visualization Of Geophysical Prospecting Data Based On WebGIS

With the development of geophysical exploration technology,the amount of geophysical data collected is increasing day by day.We have now accumulated a wealth of geophysical data,and these data collection methods,file formats,processing methods,and graphic displays are all different.The data processing and Management issues such as poor sharing and low processing efficiency have limited the research process in the field of geophysical exploration.In the age of the Internet,WebGIS was applied to geophysical exploration.Because WebGIS has the characteristics of wide access,rapid information release,and simple and flexible use,geophysical workers can use a universal browser to access the WebGIS.WebGIS system manages and processes geophysical data.The visualization of geophysical data is the main method to explain geophysical data.Combining the geophysical data visualization with Web GIS technology can effectively improve the geophysical data processing efficiency and management quality,and has important significance for geophysical exploration.Therefore,this dissertation focuses on the online visualization method of geophysical data network,and builds an online interactive geophysical system of geophysical data network based on WebGIS technology.The main accomplishments are as follows:(1)Introduced the principle and required development technology of WebGIS,and the open source technology for interactive visualization;(2)Earth geophysical data collected by mine transient electromagnetic method is used as the sample data of this paper.The principle of the detection method and grid interpolation method are introduced.The content and processing flow of the data format are analyzed.The grid interpolation model is established using MATLAB.Meshing method for simulation;(3)Complete the geophysical data DAT file format to JSON format conversion,and implement the geophysical data grid interpolation method on the Web to achieve the online visualization of geophysical data;(4)Based on the geophysical data online visualization method and WebGIS technology,the overall design of the system was completed,and an on-line interactive visualization system for geophysical data network was developed.
