  • 摘要:This article aims to introduce load balancing spatial analysis into XML-based WebGIS. In contrast to other approaches that implement spatial queries and analyses solely on server or browser sides, load balancing spatial analysis carries out spatial analysis on either the server or the browser sides depending on the execution costs (i.e., network transmission costs and computational costs). In this article, key elements of load balancing middlewares are investigated, and relevant solution is proposed. The comparison with server-side solution, browse-side solution, and our former solution shows that the proposed solution can optimize the execution of spatial analysis, greatly ease the network transmission load between the server and the browser sides, and therefore lead to a better performance. The proposed solution enables users to access high-performance spatial analysis simply via a web browser
