面向地形可视化的多种投影方式研究

Research on Multiform Projections which are Facing the Terrain Visualization

为了获得形式多样的地形可视化效果,投影方式的选择至关重要,通过对正投影、透视投影、渐进式投影和平斜投影等多种投影方式的原理与方法进行研究,分析了各种投影方式的适用性及其获得的地形可视化效果,为应用实践提供了有益借鉴。

For achieving remarkable terrain visualization production,it is serious on choosing map projections. This paper studied the theory,method and applicability of progressive,plan oblique and other projections. The terrain visualization maps using these projections are displaying. The effort is beneficial for application of these projections.
