摘要
讨论了利用ArcEngine组件在.net环境下,设计并且编程实现云南省数字等震线快速绘制的方法。除了目前通用的椭圆模型之外,引入并实现了绘制线源模型等震线。同时采用二分查找思想实现快速查找最近活动断裂、绘制等震线的算法。对初次绘制完成的等震线文件提供了参数修正、余震修正和手动修正三种修正方法,分别用于不同数据和不同目的的修正。最后通过在洱源5.5级地震和洱源5.0级地震中的应用,检验和论证了快速绘制云南省数字等震线的可行性和实用性。
The use of ArcEngine components and orcal database to design and implementation of the fast drawing method of Yunnan Province digital isoseisms is discussed.In addition to current general elliptical source model besides,the line source model of isoseisms drawing is used and realized.At the same time using the binary search ideas in order to quickly find recently active faults and drawing digital isoseisms.For the existing isoseisms file that provides three correction methods：parameter correction,aftershocks correction and manual correction,respectively applied for the different data and different purpose of the correction.Finally,aplication of Eryuan 5.0 magnitude earthquake and Eryuan 5.5 magnitude earthquake,demonstration the method of fast drawing Yunnan digital isoseisms is feasible and practicable.
