基于GIS的多波束和浅地层剖面数据集成技术研究

Integration of Multibeam and Sub-bottom Profile Data Based on GIS

依据同一测区地球物理资料的空间地理坐标参照关系,利用ArcView对栅格、矢量等多种空间数据格式的支持及内置语言Avenue强大的二次开发功能,实现了多波束和浅地层剖面数据的集成。主要流程包括多波束测深数据的预处理和浅地层剖面的生成、元数据的获取;ArcView GIS中编程实现浅地层剖面测线的分段矢量化;运用两个Avenue程序实现多波束和浅地层剖面的关联展示等。在此基础上,对多源地球物理数据的集成前景作了进一步的展望。

According to the spatial reference relationship of the geophysical data gathered from the same survey area, the author uses the supporting function for multi-style data of ArcView and the powerful developing function of Avenue, the Inner language, to realize the integration ofmultibeam and sub-bottom data. The main procedures include, the preprocessing of multibeam and sub-bottom data, segmentation vectorization of the sub-bottom survey lines within the ArcView through programming, linking the multibeam with the sub-bottom profiles using two Avenue scripts and so on. On this basis, the author also gives further expectation of the Multisource Geophysic Data integration.
