AI Technical Summary

Technical Problem

Existing WebGIS multi-source spatial data rendering technologies suffer from poor data compatibility, uneven load distribution, and low rendering efficiency. In particular, when faced with large-scale concurrent rendering requests, the system lacks flexible fault tolerance mechanisms and load prediction capabilities, leading to rendering task interruptions and resource waste.

Method used

A dynamic load balancing approach is adopted, which uses a multi-source data access and preprocessing module to achieve format parsing, redundancy removal and standardization. Combined with a load assessment model and dynamic scheduling strategy, rendering tasks are dynamically allocated to ensure node load balancing and the continuity of rendering tasks.

Benefits of technology

It achieves efficient adaptation of multi-source data and dynamic balancing of rendering load, improves rendering efficiency and system stability, avoids node overload or idleness, and meets the needs of large-scale concurrent rendering scenarios.

Abstract

This invention relates to the field of network geographic information technology and discloses a method and system for real-time rendering of multi-source spatial data in WebGIS based on dynamic load balancing. The system includes modules for multi-source data access and preprocessing, load monitoring and evaluation, dynamic load balancing scheduling, and distributed rendering. In this invention, the multi-source data access and preprocessing module achieves unified processing of multi-source data such as vector, raster, and 3D data; the load monitoring and evaluation module quantifies node load coefficients using the analytic hierarchy process (AHP); the dynamic load balancing scheduling module intelligently allocates tasks based on load status and task attributes; and the distributed rendering module adopts a two-level caching architecture to improve rendering efficiency. These modules work together to form a closed loop, effectively solving the problems of poor data compatibility, uneven load distribution, and low rendering efficiency in existing technologies, and meeting the needs of large-scale concurrent rendering.
