摘要
利用ArcGIS地理信息系统平台,结合空间分析的建模理论,以广州市白云山SPOT卫星影像图和全要素数字图数据为材料,阐述了可视域分析的过程,得出了遥感影像和数字化地形图相结合进行可视域分析的方法,输出的通视图清晰直观,为广州市森林防火信息系统望台管理提供了可靠的基础决策信息。
The use of ArcGIS geographic information system as flat roof,based on modeling theory of geographic information system in spatial analysis, and according to SPOT satellite images of Baiyun Mountain of Guangzhou City was made using the entire element digital map data as material.The paper discusses the process of analyzing visibility and deduces the method of analyzing visibility and how to associate remote sensing image with digital topographical maps.Exporting of visibility map is legible and intuitionistic,and it also can provide lookout management of the Forest Fire Management Information System of Guangzhou City with basic decision-making information.
