面向地形可视化的多种投影方式研究

摘要

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 projec-tions are displaying .The effort is beneficial for application of these projections .
