Model of GIS data warehouse for "digital seabed
Yang Zuo-sheng · 2004
A model of GIS data warehouse for digital seabed is presented. The model is composed of six layers, which are specialized data (data source), core data (DW), data sharing, data digging, application and production. The problems, such as how to make data with different formats and expression assimilations, how to manage spatial data and attribute data in the same pattern, and how to dig data from DW in visual, are discussed in detail. Based on the model, a system is developed for analyzing and evaluating the data of laser single molecale for oil and gas geochemistry prospecting in ocean.
