国产卫星遥感数据的地形渲染技术

Technology of Terrain Rendering Based on Domestic Satellite Remote Sensing Data

在使用国产卫星遥感数据的基础上,利用DEM数据提取地形特征,根据数据获取时的光照条件,建立地形光照模型,总结出一套快速易行的地形渲染技术,能够实现可视化、立体感强的三维地形表达,提供更为直观准确的地形认知。

The study was based on domestic satellite remote sensing data.We built the terrain illumination model with terrain features extracted from DEM data and illumination condition of image acquisition,and summarized a technology of terrain rendering.The technology can realize stereoscopic 3-D terrain visualization,and give us more direct and precise terrain cognition.
