数字地形模型在城乡建设用地增减挂钩项目中的应用

Application of Digital Terrain Model in Connection Project of Rural-Urban Construction Land

针对城乡增加挂钩项目点多面广,项目区零碎的情况,本文以福建省漳州市长泰县岩溪镇顶山村增加挂钩项目为例,采用mapgis模型软件平台,以现场采集的地形数据为基础,以2维地形软件cass为中介,详细介绍建立3维数字地形模型的方法和过程,运用该3维模型可为城乡建设用地增加挂钩项目的可行性分析、设计与施工提供直观的地形模型,从而减少外业踏勘的工作量,节省大量的人力物力。

Taking the connection project of Zhangzhou as an example, the paper introduces method and process of three - dimensional digital terrain model based on MapGIS platform and terrain data collected from the field, which provides the support for feasibility a- nalysis of connection project of rural - urban construction land and helps to reduce the workload and save the time and effort.
