Design and Implementation of Marine Multiple Geoscience Sharing WebGIS System Based on OpenLayers

Marine basic geological data play an important role in national defense construction and marine economic development. Based on unified data standards and specifications, building a marine basic geological data resource sharing platform has important practical significance for realizing the sharing of marine geoscience data and improving the utilization of data resources. This paper first analyzes the outstanding problems in the visualization of marine basic geological data, mineral resources and gravity, and magnetic data. For these problems, based on the existing marine geological data as the basic source data, the technical method of visualizing the spatial location of marine basic geological data through map visualization is studied, and the method is applied to the marine geological data service WebGIS system development project. The efficiency of marine geological researchers in querying geological data and the hit rate of screening data have been improved, and it has certain innovation and practicability in the service model of marine geological data.
