基于ArcGIS的土地整治项目土方量计算及三维可视化

Earthwork Volume Calculation and 3D Visualization of Land Remediation Project Based on ArcGIS

填挖土方量对于土地整治项目具有重要意义。传统计算土方量的方法有很多,但存在计算方法繁琐、工作量大、效率低下、精度不足等缺点。以某地美丽乡村建设项目局部区域为研究对象,应用ArcGIS软件平台建立数字高程模型的方法,并计算土方量,并与CASS软件计算结果进行对比分析。研究表明,ArcGIS方法计算土方量更快速、准确,且能够实现三维可视化。

Earthwork volume of filling and excavation is of great significance for the land consolidation project.There are many traditional methods of earthwork calculation,but they have disadvantages of complicated calculation,heavy workload,low efficiency,insufficient accuracy,etc.In this paper,taking the local area of Beautiful Rural Construction Project as the research object,the method of building digital elevation model with ArcGIS software platform was established to calculate the earthwork volume,and the calculation results were compared with CASS software.The results showed that ArcGIS method was faster,more accurate and it could realize 3D visualization.
