Efficient, Customizable and Edge-Based WebGIS System

Abstract

Nowadays there is a wide range of applications for WebGIS which can add great value to modern economic, and building WebGIS system for specific scenarios is the common requirement of the industry. While currently separate WebGIS systems are deployed at different sites and operated by different owners, each of which has the whole set of functionalities of WebGIS, and thus introduce high cost of development and maintenance, which is a waste of resources as most of the functionalities are the same or similar. An edge computing based WebGIS architecture is proposed in the paper to meet the need of customization by applying the idea of SaaS. In this distributed architecture, the resource load is reasonably balanced between the server and the browser, which improves the overall performance of the system. Also it utilizes edge computing to reduce the pressure on the server by sharing map tiles among WebGIS clients. The proposed WebGIS system can not only be well customized and personalized as it is edge computing base, but also be well usable for large number of visits due to its distributed feature. The experiments show 5 concurrent requests per second, as well as response speed increases by more than 38.6% against traditional deployment. INDEX TERMS edge computing, customizable, WebGIS, high performance, map tile sharing, deviceenhanced MEC.

“…ey clearly know that if they want to survive and develop well, they must move towards informatization. Only in this way can they improve the competitive strength of enterprises [10]. Yonghui et al believe that the landscaping information management system integrates modern management theory, database technology, network communication technology, and computer technology to maximize the development and sharing of landscaping information management resources [11].…”

“…where, T ij is the travel volume from traffic area i to j, O i and D j are the number of activities in traffic areas i and j, F(d ij ) is the distance attenuation function, A i and B j are the equilibrium coefficients, and their forms are shown in formulas ( 9) and (10). e general expression of the model is shown in formula (11).…”
