摘要
人类对地球的监测和模拟形成了大量的离散时序空间数据,如何有效表达这些数据以便为相关部门提供分析和决策依据,是众多信息系统建设过程中遇到的难题之一。利用网络地理信息系统(WebGIS)平台,综合应用了OpenGL,Ajax和JavaScript等技术,实现了离散时序空间数据的解析、渲染和地理底图的快速一体化动态可视化。该技术方法具有通用性,可以通过网络平台广泛应用于各类离散时序空间数据的监控(如对环境污染扩散实测数据)与预警(对模型数据),为政府科学决策和应急响应提供依据。
Most earth observation and monitoring data are discrete spatial-temporal data of massive volumes,and the efficient management,analysis and visualization of these data for decision making support constitute a very challenging task in information system construction.This study combines the latest techniques,such as OpenGL,Ajax and JavaScript on a WebGIS platform to flexibly manage and display various discrete data with fast integrated dynamic mode.The technology developed can be widely applied to monitoring various spatial-temporal discrete data such as environmental pollution diffusion data and making forewarning so as to support emergency decision-making.
