基于GIS的POM模型及其在渤海潮流模拟中的应用

地理信息系统(GIS)作为对蕴含空间位置信息的数据进行采集、存储、管理、分发、分析、显示和应用等的新兴技术,显示出在海洋领域研究的重要性.做为目前海洋研究比较流行的数值模拟技术,集成GIS在空间数据处理和解析等的强大功能,以此扩展和开发基于GIS的数值模型的工程耦合形式,成为海洋GIS发展的前沿领域.将GIS在POM潮流模型前处理和后处理中应用,进行了GIS的功能性扩展编程,以文件交换形式,形成GIS和POM模型的分散式结合,并用此方法在渤海潮流模拟中进行了测试,其中在前处理中自动剖分网格和数据的自动提取等技术极大地提高了建模、调试和后处理的效率,而后处理显示等技术的使用为以后的集成一体化开辟了途径.

GIS based POM model and its application in the Bohai Sea simulation

Geographical Information System (GIS) which contains information on the spatial location of the data collection, storage, management, distribution, analysis, display and application of emerging technologies, shows the importance in the field of Marine research. As a more popular numerical simulation technique in the marine research, integrated with CIS in spatial data processing and analytical function, et c., on this account we did the expansion and development of GIS-based numerical model in order for coupling the project form. This becomes the forefront of the development of the Marine GIS. The paper presents the application in the POM model with GIS pre-processing and post-processing, carries out to expand the functionality of GIS programming in the form of Document Exchange, forms POM model and GIS combined with the distributed, and we used this method in the Bohai Sea tide which has been tested in simulation. It greatly enhances the modeling, testing and post-processing efficiency that the pre-processing application which deals with the automatic mesh generation and the automatic extraction data technology. Then the use of GIS post-processing display technology opens the way to integration in the future.
