摘要
地理国情普查成果中面状数据需进行折刺检查,通过ArcGIS折线夹角计算工具完成折刺检查的方法存在操作复杂、局限性大、效率低下等问题,采用程序语言编程可实现折刺检查的精简化和效率化。本文通过建立面状数据的几何模型,利用向量夹角计算法来检查面状数据边线的夹角异常,形成完整面状数据折刺的检查方案,从而使面状数据折刺检查的方法更简单、高效。
In the survey of geographical national conditions,it's necessary to check the sharp of area data. Through the calculation tool of the included angle of fold line in the Arc GIS toolboxes could complete the checking.But it has complicated operation,limitation and inefficiency. The application of programming languages can solve this problem better.This paper through building a geometry model of the area data,using vector angle calculation method to check the angle anomaly of area data line,gets a programme to check sharp of area data and makes the method of checking the sharp of area data easier and more efficient.
