摘要
拆迁建筑物数量是评价线路方案的重要指标。对于尚未开展现场调查、但却有大比例尺电子地形图的线路方案,通常利用电子地形图估算拆迁量。设计人员传统的统计方法低效且不准确。本文基于AutoCAD二次开发,实现了电子地形图上线路方案拆迁建筑物数量统计的自动化。
The number of demolition buildings is an important indicator for evaluating the route plan scheme.For route plans for which surveys have not been carried out,but large-scale electronictopographic maps are available,maps are often used to calculate the number of demolition.However,traditional methods adopted by designers are inefficient and inaccurate.With the secondary development of AutoCAD,automatic calculation of the demolition numbers for route plan scheme on electronictopographic maps is realized.
