摘　　要：TIN作为数字高程模型的一种,由于能较好地顾及地貌特征点、线和表示复杂地形表面而得到广泛应用。结合公司业务和选用的软件平台,介绍了TIN模型制作的流程,对ArcGIS和Geopak软件平台建模技术进行比较,分析了各自的优势与不足,在数据的处理要求方面作了总结,为制作精细数字高程模型提供借鉴经验。TIN is one of digital elevation models. Since the geomorphological features such as points and lines can be taken into consideration to represent the complex terrain surface, it is widely used. The pa-per, combined with daily business and the software platforms used, introduces the TIN modeling process first. Then comparison between the modeling technique on ArcGIS and on Geopak software platform is carried out. As well, their advantages and disadvantages are analyzed. Finally the data processing re-quirements are summarized and the experience in producing fine digital elevation model is provided.
