摘要
GIS作为一种新兴的交叉学科在空间数据处理和解析方面具有强大的扩展功能,已经在众多领域得到了广泛的应用.本文针对开采沉陷地表移动变形计算问题,在GIS平台利用空间数据模型给出了预测计算中不同坐标系的转换公式及其空间数据库的构建,并讨论GIS与专业工程模型的耦合方法,提出了基于COM的模型耦合方法应用于系统的构架.实践证明,该方式下GIS与开采沉陷专业工程模型结合具有明显的优越性,对其他相关专业领域的耦合应用具有一定的借鉴意义.
As a new crossed technology, GIS （Geographic Information System） has a powerful extending function on the spatial data process and analysis,and it has been widely used in many fields. In this paper,the transformation equations between GIS and working face coordinates are given so as to calculate the ground deformation due to mining subsidence, and to create the spatial database with the spatial data model in the GIS platform. Also, the coupling methodologies between GIS and professional engineering model are discussed and put forward the construction by use of the general COM technology. It can be concluded that the proposed method in this paper can play an important role in integrating GIS with mining subsidence, and wiU help GIS as a powerful tool to be used in the other related fields for further applications.
