摘要:

针对跨平台多层体系结构的GIS系统要求,设计一种GIS可视化系统架构。该构架实现了GIS可视化系统常规功能和跨操作系统平台,具有动态使用多种绘制引擎、动态组装绘制算法、带有自适应输出设备等特性,能适应需求变更和图形技术的发展。在VegaGIS平台上得到实现,已被成功应用于多个领域。

Abstract: Aiming at the request of Geographical Information System(GIS) system for cross platform multilayer structure, this paper designs VegaGIS visualization system architecture. The architecture realizes the general function of GIS visualization system and the cross platform for OS. It has several characteristics including self-adapting to multiple operating system, dynamic rendering engines, dynamic rendering algorithms, and self-adapting to output devices. The design is implemented on the VegaGIS platform, and is successfully used in several fields.

Key words: visualization system, VegaGIS, Geographical Information System(GIS)
