Abstract
In the power grid WebGIS application, the graphical display of power grid equipment is one of the most basic functions. However, the massive data brought by the growing number of power grid equipment brings difficulties to both server-side storage and client-side rendering. Aiming at the characteristics of power grid GIS data, this paper presents a Web Worker-based grid WebGIS rendering optimization method and uses a program to implement it. The method improves the rendering speed of the client and optimizes the display effect by marking the displaying rules after data vectorization, simplifying the line data, generating vector tiles dynamically, and station label dodging. The result of the test shows that this method can effectively improve the fluency and user experience of existing power grid GIS applications.
