摘要
分析了民航告警系统对地理模型的需求,设计了两种支持地理模型,探讨了模型的具体参数、采集方法,实现了一个应用实例。
This paper analyzes the request of civil aviation early warning system for geographic model. Two supporting geospatial models are designed based on different warning systems. Several parameters and data acquisition methods for the models are discussed. Finally an application example is provided.
