摘　　要：松原灌区项目初期获取了大量的测绘基础数据,在使用ArcGIS软件处理数据时,占用大量的电脑资源,会导致软件无响应,甚至电脑死机。这是由于数据量比较大和处理程序是单线程程序的缘故,如果使用多线程程序来处理海量数据,可以完全解决上面遇到的问题,而且由于数据处理算法是一样的,所以处理结果与单线程程序的处理结果保持一致,基于此方法可以扩展应用到其他海量数据的处理。Songyuan Irrigation District project had been gotten a lot of the basic data of Surveying and Mapping in early period： With ArcGIS software processing those data,it took up a lot of computer resources,led the software was not responding,or even the computer crashed.This is due to the greater amount of data and processing program is a single-threaded program,if a multithreaded program was used to process huge amounts of data,it can completely solve the above problems encountered,but also due to the data processing algorithm is the same,so the processing results consistent with the single-threaded processing,so the last program method can be extended to other massive data processing.
