摘要
通过阐述建立大型公共绿地数字地面模型的方法,提出了绿地地表曲面面积及土方计算的模型和算法,通过编程来加以实现,成功地解决了大型公共绿地的项目需求。同时对大型公共绿地实现了计算机自动成图及土方计算的内外业一体化。
This paper describes a method of establishing a digital terrain model for a large communal greenbelt and presents an algorithm for calculating the curved surface area and the earthwork of the greenbelt. It successfiAly meets the need of these large communal greenbelt projects through integrating computer automatic graphing and earthwork valure calculation into a uniform system.
