# 基于规则格网DEM计算水库库容方法研究--《吉林水利》2013年11期

【摘要】：传统库容计算方法是在已有的地形图上量测闭合等高线包围的面积,用相关公式计算并绘制库容曲线。当精度要求较高时,需到现场实测更大比例尺的地形图。传统计算方法的缺点是工作量大、费时,且计算精度低。基于高精度DEM分析技术来计算库容,满足了快速、高精度计算库容的要求。

1引言传统库容计算方法是在已有的库区1:5000或更小比例尺地形图上量测闭合等高线包围的面积。以前是使用求积仪来计算等高线的包围面积,传统做法是每条等高线量测3次,取其平均值为该条等高线的包围面积。在计算机技术引入测绘行业以后,使用计算机程序可以精确计算等高线的包
