Research on geospatial data visualization based on GIS and reverse proxy

Based on the practical work, this paper discusses the current visualization techniques of geospatial data. Based on the traditional method of publishing geospatial data service by GIS server, when the data service has been published, it is not convenient to change the layer organization structure of the current data service. When the layer combination structure of geospatial data service needs to be changed, it can only re-publish the new data service. When a large number of data services are published, the server occupies a large amount of memory resources and deteriorates the server performance. This paper proposes a visualization method of geospatial data based on GIS and reverse proxy. When the data service has been published, it can flexibly conFigure the layer structure of the data service according to the actual work needs. By means of computer reverse proxy technology, the security of geospatial data sharing is improved, and the problem of GIS server performance degradation caused by re-release of data service is avoided.
