【摘要】 论述了在进行工程勘察软件设计中实际存在的一些问题。针对这些问题在对钻孔采样数据管理时,通过进行科学的数据空间的划分和结构重组提出了一种新型的钻孔数据管理方案,并成功地利用了的维数据处理功能解决了实际存在的困难。文章就该方案实现MAPGIS2.5的数据模型以及模型中使用的关键性技术分别进行了阐述。最后讨论了该模型可能存在的问题以及相应的解决方法。更多还原

【Abstract】 In this paper, some practical problems are discussed when designing software about projection survey. In the process of managing drilling hole data, we aim at the problems to present a new way to manage the drilling hole data by dividing and reconstructing data space scientifically. Meanwhile, the practical difficulty is solved by using function of 2.5 dimensions data in MAPGIS. So, the method of how to realize the new data model and several critical techniques in the model are disserted. The probable problems in the model and counterparts of answers are discussed in final.更多还原
