摘　　要：针对三维可视化技术在地理景观表达中的应用现状,设计了一种基于二维、三维及360°全景技术的地理景观多方位可视化方案,探讨了三维地理景观多方位一体化表达系统的构建流程以及关键技术;并结合传统制图、三维建模、360°全景、Html等技术,采用地貌晕渲图、三维场景和360°全景实时联动的方式构建了三维地理景观多方位一体化表达系统,实现了对三维地理景观的多方位可视化与空间分析,在实际应用过程中取得了较好效果。In view of the three-dimensional visualization technology present application used in the geographical landscape expression, a kind of multi-direction visualization project of geographical landscape was designed based on the technologies of two-dimension, three-dimension and 360 degree panorama. The process and key technologies of the three-dimensional geographical landscape multi-direction expression system were intro- duced. Combined the technologies of cartography and three-dimensional modeling as well as 360 degree panora- ma, the multi-direction visualization system of three-dimensional geographical landscape was composed and multi-direction visualization and spatial analysis of three-dimensional landscape were achieved by real-time in- teraction of hill-shading map and three-dimensional scene as well as 360 degree panorama. The satisfactory effect was shown in the practice.
