Design And Implementation Of Field Geological Data Sharing And Visualization System Based On Android And Web

Faced with the massive field geological data under the current geological big data environment,it has become an inevitable trend to realize the sharing and visualization of field geological data.However,the existing geological data management platform has poor data compatibility,low visualization,and field geological data acquisition have many intermediate processing links,which greatly restrict the sharing and visualization of field geological data.To solve these problems,this paper designs and implements not only a Web-based geological data sharing and visualization system but also an Android-based field geological survey system.It is expected to provide a complete set of solutions for digitalization collection,field preprocessing,sharing and visualization of field geological data.Then taking Sijiao Island in southeastern Zhejiang Province as an example to verify the practicability of the system implemented in this paper.The main contents and achievements of this paper are as follows:(1)To solve the problems of low digitalization and many intermediate processing links of field geological data acquisition,a mobile geological survey system based on Android platform is designed in this paper.Except for the common field functions such as virtual notebook,photography,navigation and positioning,weather viewing,phenomena preview and so on,it also supports the field calculation of complex geological coefficients and real-time processing of field images.The system implements field geological digital acquisition and reduces the intermediate link of field data processing,which lays a good foundation for field geological data sharing and visualization.(2)To solve the problems of poor data compatibility and low visualization of existing geological data management platforms,we design a geological data sharing and visualization system based on B/S architecture.Without plug-ins,it can upload and download geological data through browser access,as well as the integrated display of orthophoto,panoramic and three-dimensional model data.By this system,researchers can have a clear understanding of geological phenomena point even if they work indoors.(3)The application research of extracting dykes and related fractures on Sijiao Island shows that the field geological survey system implemented in this paper can effectively improve the efficiency and quality of field work,especially the image preprocessing module,which points out the direction for indoor research and achieves rapid and accurate extraction of dykes and fractures in a relatively short time.The geological data sharing and visualization system implemented in this paper provides a good platform for field geological data exchange and sharing,and field outcrop information can be more intuitive and visualized by using visualization technology.
