【摘要】 运用二维浓淡栅格的多维信息可视化表示方法,首次提出基于 CTDB 地形数据库的"开发—表征—寻的—校验"设计思想和多重复杂地貌综合寻的方案,将基于 CTDB 格式的高分辨率 CGF 地形数据库根据高程信息、土壤类型、地表特征、物理特征等进行多维信息可视化,并利用网格信息,根据特征自然或人文地貌对地形数据库进行地理位置寻的与校验;为 CGF 的路径规划、避障决策以及场景的三维可视化提供了直观依据.更多还原

【Abstract】 Proposed a method of rich and lean grid for visualization of multi-dimensional information."Development-Visualization -Marching-Verification"designing theory based on CTDB terrain database and multi-sophisticated-factors involved terrain marching method are all discussed for the first time,then mixed the information of altitude,agrotype,terrain skin and physical features provided in terrain database using CTDB criterion,a multi-dimensional information visualization system of CGF terrain database is presented.Furthermore,combining the information of grids,special natural or manmade physiognomy,an algorithm in finding and verifying global position according to high graphics is adopted.The application presents an intuitionistic aid for CGF route planning, decision-making,3D visualization and so on.更多还原
