摘要
土方量的计算是土地整治项目规划设计的重要内容之一,准确快速地计算土方量对开展规划设计、控制总投资及分配资金具有重要意义,直接关系到土地整治项目的科学性和投资预算的合理性。本文以新建县流湖乡新塘村屈家垄里土地开发项目为例,分别应用ArcGIS和南方CASS技术进行土方量的计算,并对这两种方法进行了分析比较。通过分析得出,虽然ArcGIS计算土方量的精度比CASS计算的结果高,但是对基础数据的要求也高,CASS软件尽管精度略低,但是运行简单、快速。
Earthwork calculation is one of the main tasks in the planning and design of land consolidation projects .Calculating earthwork accurately and efficiently is very important for land planning and design. Directly related to science of land improvement project and rationality of investment budget .In this paper,take a land consolidation project of xinjian liuhu Country of Jiang xi Province as example, ArcGIS and CASS7 were used,and two methods were compared .By analyzed,although ArcGIS is more acculate than CASS7, ArcGIS based data require higher demands,and CASS based data require lower demands, but it is so simple and quick .This paper carries on the simple analysis contrast on ArcGIS and the CASS equalization of earthwork＇s process and the precision.
