| 摘 要： | 随着传统GIS应用向三维立体方向发展,三维虚拟场景在信息认知、空间规划管理、时空挖掘与分析等方面的应用逐渐成为研究热点。本文基于Skyline平台集成遥感影像数据、地形数据、纹理特征数据、倾斜摄影测量数据、三维全景数据和三维模型数据,构建了集虚拟海岛海岸带模型、虚拟海底地形模型和虚拟水体模型于一体的虚拟海洋场景,并针对场景构建中涉及的多源影像数据集成技术、多尺度影像实时切片技术和基于OGC服务的数据集成技术开展了研究。构建形成的虚拟海洋场景在海洋应用服务系统中开展了实践应用。

| Abstract: | With the development of traditional GIS applications, the application of 3D virtual scenes in information cognition, spatial planning and management, spatial-temporal mining and analysis has gradually become a research hotspot. This paper integrated remote sensing image data, terrain data, texture feature data, oblique photogrammetry data, 3D panoramic data, and 3D model data to construct a virtual ocean scene that includes a virtual island coastal zone model, a virtual submarine terrain model, and a virtual water body model on the Skyline platform. The technology of multi-source image data integration, multi-scale image real-time slicing and OGC service-based data integration are studied. The virtual ocean scene constructed has been applied practically in the marine application service system. |
