ArcGIS在土地整治项目前期土方计算中的应用

Application of ArcGIS in Earthwork Calculation at Early Stage of Land Remediation Project

基于ArcGIS平台,应用土地综合整治项目的基础数据,通过不规则三角网(TIN)对研究区建立了数字高程模型(DEM),探讨了ArcGIS在土方量计算中的应用,并对研究区的土方填挖量进行了计算。结果表明,应用ArcGIS计算土方量原理简单,速度快,能够实现三维可视化,具有可行性。

Based on ArcGIS platform and the basic data of comprehensive land remediation projects, the triangulated irregular network （TIN） of the studied area was used to establish a digital elevation model （DEM）. The application of AreGIS in earthwork calculation was explored, and the digging and filling amount of earthwork in the researched area was calculated. The results showed that applying ArcGIS to calculate earthwork had the advantages of simple principle, fast speed, good feasibility, and three - dimen- sional visualization.
