摘　　要：南方测绘公司开发的南方CASS提供了多种土石方计算方法,但其追踪出来的挖填方0界线是用直线在方格内模拟的,与实际特征不符,故降低了土石方计算的精度.主要探讨如何在南方CASS中进行2次开发,实现挖填方0界线的自动追踪,并以实验为依托分析追踪结果的精确性.The CASS （the software made by the Southern Survey Company, China） offers a variety of methods for earthwork calculation, but the precision is low because the dividing line of the earthwork is a straight line in any grid of CASS. The auto-tracing of the earthwork dividing line in CASS is therefore developed in this paper. The precision of this method is then analyzed based on an experiment.
