公路工程中海量数字地面模型的实现及应用探析

Detailedly Analyzing the Realization and Application of Substantive Digital Topography Model in the Highway Engineering

本文针对当前应用的实际全面阐述了公路工程中数字地模涉及的各种技术,结合当前计算机辅助设计的发展现状就数字分区技术和构网前后的处理作了较为详尽的叙述,对公路设计人员有一定的借鉴意义。

A variety of technologies of digital topography model, which are involved in the highway engineering, are illustrated in the paper. Combining with the recent development status of CAD, the technologies of digital partition and the disposal methods about pre-constructing-net and post-constructing-net are detailedly discussed.
