利用ArcGIS管理和分析海底探测数据

利用G IS可视化工具对海底探测数据进行管理,建立了剖面性数据和面状分布数据间的空间可视关系,为海底科学研究的可视化提供了一条捷径。通过对浅层剖面数据特征与海底地形地貌和沉积物分布之间关系的研究,可进一步挖掘沉积物分布的成因机制和沉积物的来源。采用标准的地理空间数据模型geodatabase对浅层剖面数据、海底地形地貌数据和海洋沉积分布图件进行存储管理,有利于海洋科学数据和研究成果的共享。

Manage and Analyze the Data of Seafloor Survey with ArcGIS

This work provides a GIS-based visualization tool for managing the data of seafloor survey(sub-bottom profiling,multibeam bathymetry and side-scan sonar).Combining these data with our increased ability to georeference spatially related datasets provides us with a powerful tool for establishing potential relationships between seafloor morphology and sub-surface processes.A detail analysis of sub-bottom profiles and bathymetry,sedimentary distribution can ulteriorly find the sedimentary process and origin.Geodatabase-based marine data model for managing sub-bottom profiles,bathymetry and sedimentary distribution can facilitate the share of marine scientific data and results.
